[@jasonlee1483]

Hi Peter, are you a scuba diver? I am sure that I recognise you.

[@jrosedds42]

When the situation allows, Hi-Res mode results in less noise as well. Also, using masking in the sharpening controls in LR to avoid sharpening noise in the out of focus areas. But as you said, ETTR and keeping ISO as low as possible are the real keys to minimizing noise, and both of those techniques are so easy with Olympus cameras. Also helps to come to the realization that a bit of noise doesn't ruin an otherwise good photograph. Excellent video, Peter.

[@ForsgardPeter]

Thank you. Yes, High res mode can also work in reducing noise.

[@markwagner1328]

Peter, one method I use a lot is exposing to the right without the histogram. In aperture priority mode I use the exposure Compensation dial and simply raise the exposure by 1/3 or 2/3 of a stop. This, I find, is much easier than having to constantly check the histogram. It's so much faster. Usually, just over exposing by only 1/3 stop dramatically lowers noise without making the image looking too overexposed.

[@alpcns]

Learn to appreciate noise which sometimes creates a nice artistic foundation.

[@ForsgardPeter]

Sometimes noise can be really good, as you say it is not the amount, but the caracter of the noise.

[@GLBProductions]

I do live music photography so my pictures always contain a lot of pleasing noise :D

[@grantmedical]

Thanks Peter! Very useful! I have embraced some the "noise" or "digital grain" of the high ISO (>10,000) by converting my photos to black & white and treating the noise as "film grain"... 😆... Sometimes by playing with the shadows and actually deliberately underexposing them I can create moody images and lessen the appearance of noise that way... Anyhow those are two things I do in addition to what you have mentioned... Thanks again!

[@rickbear7249]

Another very useful video, Peter. Just worth mentioning that, in Focus Stacking mode, the stacked image is a single composite jpeg, BUT if you're set to save LSF+RAW, then you'll also have 8 RAW image files that can be merged using third-party post processing software. So, while it's true to say that the output of in-camera Focus Stacking is that one jpeg, Use of LSF+RAW doesn't totally limit you to jpeg. This is how we professionals work in product photography. Rick

[@ForsgardPeter]

That is true. If you want to use raw then using only focus bracketing might me a good idea. Then stack the images in post.

[@rayjenkins2754]

Well expressed tips & thanks for doing this. I have a Panasonic Fz2500 1 in. sensor bridge camera which has a SCENE mode on the dial. Within this mode is a selection called ' Handheld Night Shot ' which is used in handheld lower light situations. It takes 5 rapid exposures, using higher ISO & shutter levels, which helps with noise as well as ' freezing ' motion , then - in camera - they are combined into one composite image. The results are very sharp & detailed. Regrettably Panasonic chose to leave this feature ' off ' of the higher end G9 camera, although it still resides in the G9's intelligent Auto + mode but here it's use is applied only at the ' desecration ' of the camera.

[@borderlands6606]

I have a Panasonic GX80 with this feature, and it works very well. However I *think* it produces a jpeg image like the Olympus version.

[@LeoSavantt]

Great tips, many thanks. Would you consider doing a video on using the bundled flash that comes with OMD and Pen F cameras?

[@ForsgardPeter]

Thanks. I could. I am not really user of the flash, but that is a good idea.

[@LeoSavantt]

@@ForsgardPeter The reason I ask is that I have failed to produce good results with the bundled flash, both as a light fill in for outdoor portraits and also indoors at family gatherings. Either my technique is wrong or I need to upgrade to a more expensive Olympus flash, or perhaps both.

[@meredithpottery]

That would be so useful! I haven't a clue how to use mine!

[@ookiemand]

Tip1: use a wide fast lens to let in more light! Tip2: use a fill flash to lift the shadows, as well as the subject. Tip3: use a curve to darken the darkest part of the shadows, flattening out the noise. Tip4: use the zebra's a 100% to quickly set the perfect exposure to the (b)right of the histogram.

[@ookiemand]

5b, a modern camera with a larger pixel pitch/size. GH5S 12MP does level the noise playing field producing about 2 stops less noise then the 20MP. In terms of noise you can approximate a 20MP M4/3 sensor with a 80MP 35mm sensor. The GH5s you can compare to a 48MP 35mm sensor like the S1R has. Tip6: Use fast glass and a speedbooster. Sigma 18-35 F 1,8 + Metabones speedbooster yields about a F1,2 amount of light.

I am used to keep the ISO as low as possible and I tend to slightly keep my shots underexposed, all these in fear of noise. A slight overexposure and lowering the exposure in post is a new method for me to try. Thank you for the tips (hopefully got it right..) !!

[@ForsgardPeter]

It is better to make the image as bright as possible and then lower the exposure in post. The image looks first a bit dull, but once you lower the exposure it will a lot better with less noise.

[@guyjordan8201]

Good ideas clearly presented; this is why I like your videos. Others have offered but so will I, adding light. At some point, using flash and other controlled lighting is an important option.

[@southernshutterbug1436]

Greetings to you Peter and your viewers from the other end of the globe! Another good video sir, however, one key aspect I feel you could have included more directly (although in many ways you touched on it indirectly) is Shot Noise. This affects any camera no matter the sensor size in use. Shot Noise is though, happily, something over which we have direct control from the start at any ISO setting. Simply explained, if we imagine each pixel as a bucket for "light drops", the longer we leave the tray of buckets (the sensor) in the rain (light), the more drops will be in each bucket and the more even the signal (number of drops in each bucket) will be over the sensor. The shorter the period of time we leave the tray in the rain (i.e. the faster we open and close the shutter) the fewer and more scattered the drops will be in the buckets - and the gaps in-between where there are no drops at all are what we see as noise - especially in shadows. When there is a light drizzle (low light) as opposed to a steady downpour (good lighting) you will need to have the tray in the rain for longer to get a good number of drops in each bucket to ensure an even signal. So, practically: Using a fast shutter speed in low light (which is what you get if you simply rack up the ISO value) ADDS shot noise where a longer shutter speed - in the same conditions with the same elevated ISO - will tend to have less noise for the processor to handle from the start in downstream processing. You can test this by using the same ISO on a static scene and using different shutter speed/aperture combinations to expose it. Extremely fast shutter speed exposures (on any camera) will exhibit areas of visible noise in the shadows, even in good daylight, where a longer speed in those very same conditions will tend to smooth those areas out. Summary: If noise really bothers you or needs to be minimised as much as possible, start by using the slowest practical shutter speed in the particular conditions in which you are shooting (which by implication will mean the lowest practical ISO as well) wherever possible - even when using all the other tips in the video. It's always a balancing act between ISO, shot noise and required depth of field - but then, that's what makes our profession such a challenging one and keeps us on our toes every day. In my view noise, per-se, is not always a fault in an image anymore than grain was a fault with film. Sometimes noise can help form part of the soul of the image and add to its mood and message.

[@rickbear7249]

SouthernShutterbug. I love your buckets analogy. A very good clear explanation. And, once again, it's important to remember that our sensors only ever work at ISO 200, therefore, balancing exposure aperture and shutter speed around ISO 200 will always yield the least noise. Higher ISOs are actually a deceit. You get an underexposed image that the camera's software attempts to boost back to the sensor's native ISO 200 light exposure, which is where the noise comes from.

Hi Peter, thank you for your interesting report(s). I take a small exposure bracketing (-1 / 0 / +1) on non (or less) moving subjects and than combine them into a single image in Lightroom CC (only one click!). So I have a good dynamic range and also a low noise - everything in RAW.

[@ForsgardPeter]

[@alexandrejosedeazevedoribe8892]

Hi Peter; Stacking does not force you to abandon raw format as the Olympus cameras store the raw files that were used to produce the in-camera jpeg file. As such you can stack these raw files in post processing in photoshop or a similar program. Besides that Olympus cameras have also bracketing that can be used as a technique to reduce noise in post processing.

[@ForsgardPeter]

Yes, you can. In this case the camera does the stacking.

[@GeirBakkenVestfold]

Hi Peter Interesting topic. I have an E-M5 II and I use DXO Photolab for raw convertion and noice reduction. And it is very capable of cleaning up noice without ruining detail. Lately I have experimented on creating "bokeh panorama" where I take 6to 130 pictures with a tele zoom and do the raw convertion of each of them with noice reduction, and then stitch them together in Image composite. Then I edit and reduce the size and the result is crisp sharp images where the remaining digital artifacts and noise is reduced many times by size in the process.

[@ForsgardPeter]

That is great way of making cool looking images.

[@montxsuz]

Thanks for that. My extra tip? DxO PhotoLab Prime or DeepPrime. :)

[@ForsgardPeter]

DxO Photolab 4 DeepPrime is the best at the moment.

[@joerf9351]

As you have said it, M4/3 has a worst performance in low light when compared to full frame, but even in dim light and up to F4.0, I'm confident that my good old Em-1 Mk I can handle it and produce great results. Never have I been bothered by the noise in my images...

[@HarleyPebley]

I'd not heard of the multiple exposure method. Cool for when you don't have any movement in your image. Thanks!

[@davidblack2632]

Great methods for reducing noise. I never thought of using the 60 fps for getting images to stack for reducing noise. I have used Live ND in the E-M1X and also HiRes to get lower image noise.

[@ForsgardPeter]

Yes, high res is also a good method.

[@metamurph]

To me, many of the in camera options are there for people that either don't want to or don't have the software to post process and you can still post process a jpg, crop, whitebalance, etc. just not as much room but if they "camera" gets it right and then you just want to apply your color curve...that is really the learn from the cel phone for the mainstream audience. That is part of why I say, partner with Google, run android on the camera (then you get the nice UI, apps run on it etc) the advantage of the "camera" is the glass, the battery, and the memory + plus larger sensor and IBIS -- but lots of good tips here.

Hello Your tips are really good I just would like to ask one question. How is the image stack and done in photoshop to reduce the noise? Can you please elaborate on that? Thank you.

[@ForsgardPeter]

You need to make several images. Then you open all the images and have then as layers as a one image. If I remember correctly you then lower the opacity of the images from top top bottom. The amount of opacity depends on how many layers you have. There must be a few tutorials in KZbin.

[@miquelgilcaballe]

Thank you very much for your contribution as always perfect and very helpful. Noise reduction with focus-on stacking is spectacular. It works very well. One question, if I leave Noise Reduction (Auto) + Noise Filter (High) + Process enabled. Permanently low ISO (Detail Priority) for all photographs do you think that's not right? Can it affect the quality of my images?

Solid info, Peter. Will try image stacking. My go-to method is proper exposure combined with low ISO. I hear that more cameras have become “ISO invariant” as a way to reduce noise. Would appreciate your perspectives on this topic, perhaps in a follow-up vid. BTW, excellent thumbnail for this post - illustrates subject perfectly.

The most obvious one you missed is using a speedlight, if the situation allows it. In combination with ETTR, that becomes the most powerful noise reduction technique. I obviously realize, you won't be able to do that for landscape or architectural photography, but when the situation allows it is the best way to reduce noise. Hence carrying a flashgun with you. All the techniques you have mentioned are valid too, some more than others. But this is my number one tip. Flashgun use in conjunction with ETTR are, may be take several shots, to ensure highlights are protected, whilst using the ETTR method in conjunction with a speedlight. And if you really want to go in the direction of overkill, the methods I mentioned in conjunction with exposure blending in Photoshop. Followed then by processing the image to your intent or artistic interpretation.

[@ForsgardPeter]

[@jonerikrolf2029]

Peter - Very good video on noise issues, but you didn’t mention using the in-camera “curve” adjustment of contrast for high, low and mid bands of exposure. One can suppress blowouts (orange) and crushed shadows (blue in EVF). Some reports state that this method only effects the jpg image and not the raw image file. I see subtle differences in the raw image histograms for exposures with and without the use of the in-camera curve tool. What do you say re the impact on the raw file? Note that in video log LUTS, suppressing contrast and saturation work similarly, but do they work on video RAW files?

[@ForsgardPeter]

I does not affect the raw files, but it might give a better info and help you to get more accurate exposure.

[@davidponce1901]

Thank you for the good tips Peter👍

[@tizio54]

Question: Instead of multiple exposures (with a tripod I assume, and only for static objects) couldn't I just use a long (multiple second) exposure at a lower ISO setting, to get less noise? What would be de advantage of using multiple exposures (at high ISO) over a (long) time exposure at low ISO?

[@ForsgardPeter]

It is not always possible to use long exposures. If you are able to use LowISO tehn you should use it. Most likely the noise that comes from long exposures is less than the one that comes from high ISO.

[@photaudiotech5550]

“Noise” (actually signal to noise ratio) is not caused by iso. It is mainly cause by the quantity of light you gather to make the photograph. The lower, the lower the snr. Image stacking is just adding more light. Thinking that iso amplification is the cause of the noise is a mis conception. You can shoot at iso 1600 and iso 100 with (same shutter speed and aperture brighten in post) you we get similar snr, a bit better with iso1600 for other reason. The real advice is get the maximum of light as possible and you can get rid of advice 1, 4 and 5.

[@ForsgardPeter]

That depends on if you have an invariant sensor or not. I have not tested if Olympus has an invariant sensor.

[@photaudiotech5550]

Peter Forsgård wasn’t my purpose, if you have an invariant sensor you will get the same SNR with iso 100 and 1600. If you don’t have one you will get a better snr at 1600 than 100 (for same quantity of light gathered). Meaning that in low light condition it is better to increase iso than brightening in post. This is due to the fact that when you brighten in post you are increasing signal and all type of noise. When you amplify with analog iso you are amplifying signal and all noises except one : the read out noise of your sensor. Which in most photographic situation you do not see because dominated by other type of noise (the photon noise).

[@photaudiotech5550]

Peter Forsgård all that to say that the advice 1) use lowest iso as possible is kind of twisted. The advice I would say is : - get the maximum quantity of light When you cannot get more think about what you want to prioritize: * dynamic range: better to shoot low iso and apply the right curve in post. * noise (specially in shadows) better to increase the iso. Cheers.

[@ron5935]

Even base iso has noise. Compose and make proper exposure, Make another exposure at base iso 4 stops under. You should have done NR on each RGB layer and saved saved results . Apply saved NR to 4 stop under, then boost to proper exposure. This works because we are not boosting noise from base for high iso like what the camera does, but raising a "clean" image without noise. I can do this with my M8 which has really poor high iso image quality.

[@WMedl]

Dear Peter, very interesting methods and I will examine stacking though the disadvantage is abandoning the RAW! But all your images have been shot in more or less bright daylight, thus the noise seen is due to mere signal amplification reducing SNR and maybe some camera flaws... In unfavorable light conditions most of the noise is due to light noise because of underexposure - the higher the ISO the higher the underexposure and thus the noise due to the stochastic nature of photons. The bigger the pixel area the less variance and thus the less noise. While the E-M1 Mii has a pixel pitch of ca 3,3 micrometer, that of e.g. the Sony A7iii is near to 6! And noise reduction in the camera does not correct that sort of noise correcting only hot pixels. Sometimes I convert noisy images to black and white and even enhance the graininess to mimic images of the old grand days of film!

[@borderlands6606]

Yes, it is counterintuitive but if you use high ISOs in good light, noise levels are well controlled. I also agree that converting to black and white loses the worst effects of noise. The two best options are intelligent use of flash, or learn not to worry about noise!

It is a better camera. It has 20MP sensor and a better processor. How much is the image quality better is more a less a personal opinion. E-M1 MKII also has the high res mode for 80MP photos. If you have chance a borrow one, you should try it out.

@@ForsgardPeter I would love to try one but its not that easy. A leap of faith is the only option I have

Stoic Student you should check out Joe Edelman's 46feet billboard print. My biggest do far is 27 inches and no problems with it.

and finally.....which are the tips?

Noise? DXO photolab 2 prime..done

[@ForsgardPeter]

That is also a way.

[@blackdarkghost1212]

The word noise in 'long exposure noise reduction' has nothing to do with noise that's traditionally associated with high ISO. Two completely different concepts, but one vocab item

[@ianbrowne9304]

BUGGA!!! That's what I had wrong --- I just turned the volume down to get less noise . Ok; I'm leaving :lol: But before I go --- I have recently learnt digital noise is just that; digital; and does not show on a printed photo . I haven't print a photo for years so have no idea . I often think ''sharpness'' and ''noise'' are rather over rated; or over worried about with modern digital cameras.

[@ForsgardPeter]

i agree that nose and sharpness are over rated. Where did the idea that noise does not show prints comes from?

Yes it is. Please do.

No Peter you didn't miss anything in your presentation. As a matter of fact it was really good. Thank you for educating me. Good Job.

Thank you very much.

ETTR might be good for cloudy countries, but for the southern hemisphere BEWARE, any Hint of sunlight wont be recoverable (even from RAW)

[@ForsgardPeter]

ETTR is good for any situation. The key is not to blow the highlights no matter if there is clouds or not.

[@wanneske1969]

Unfortunately exposing to the right is not Always possible, for instance during a dark concert, a wedding etc...

[@ForsgardPeter]

It actually is. The exposure can always be taken down. The results will be better. With the highlight/shadow flag colors you can control where the highlights are. Anyways it is always wise to exposure as right as possible.

[@andreika6681]

@@ForsgardPeter just show him a couple of your images of a dark concert with your oly to prove it...

[@imnewtothistuff]

I didn't know Olympus still made cameras! That being said, ISO on digital cameras is nothing more then a noise reduction circuit, It shouldn't even be called ISO! Additionally at 6:09 The menu shows a noise filter that can be toggled on and off as well as many iso features. That means there's a noise filter for the noise filter! Now I understand why people are confused! And probably why I haven't heard the name olympus cameras mentioned in years!

[@zardosspinosa6944]

I think most of us use RAW these days

[@andreika6681]

@Good Day i'd say, most of Photographers today have cameras without raw :-) 90% of phones don't output raw

[@jalakanen]

I have one simply method. I don´t care about noise.

[@ForsgardPeter]

Easy solution!

[@andreika6681]

chances are after a while you'll evolve into making your pix noisy intentionally :-)

[@SergiMedina]

Number one isn't so easy. ISO is what is it is (and it's not simple)... Lowering the ISO in fact implies getting more light to the subject/scene (as ISO doesn't change the amount of light reaching the sensor), but on most occasions you can't. So it's not about lowering the ISO per se and underexpose (which can be even worse in some cases). It's about trying not be forced to raise the ISO. So ISO has in actuality little to do with noise. Also, be careful when exposing to the right. It's not always good (in fact, rarely is).

[@ForsgardPeter]

Why ETTR is not good?

[@SergiMedina]

@@ForsgardPeter Hi, Peter! Exposing to the right may be beneficial in some cases, but it's a bit risky since if not done correctly and in the right situation, could lead to lost highlight details and maybe other problems. Not to talk about the need to correct the picture further in post. The issue is worse in digital, where highlights clip relatively easily and they are hard to impossible to recover, unlike film, which it's said to be the opposite. Also, remember there's nothing like a properly exposed image.

[@ForsgardPeter]

The point is not to clip the highlights. That is were the flag colors come in handy. If you set the red/orange to turn on when the when the value hits 254 highlights wont be blown out. There is still a bit room if needed. Actually the 254 is for the jpg and there is still a bit room in the raw file. ETTR is risky if you do not have all the info in the EVF. That is exactly what I was saying about DSLRs.

[@speedohugo8646]

Quit blaming the iso....the more light coming in thru the lens the less noise....simple as that.....

[@ForsgardPeter]

Yes true, but since every camera produces more noise when using higher ISO, I think the video has a point.

best tips is ...buy a FF camera with low resolution
