I totally disagree. Saying that you have to use a certain setting (whatever it is) forever, is like saying that you must eat spaghetti for the rest of your life, no matter if you have celiac disease, you are at your wedding reception, etc. It makes no sense to remove ISO from the equation by fixing it at a certain value. ISO is analog gain and therefore amplifies the effects of SNR, so whenever possible, if you can afford it, whether for lighting conditions, exposure time or aperture, it is best to minimize it. There is no point in adding gain for free

I've used a polarizer to dial between reflections and seeing through the glass in street photography. I imagine you could use it to boost the reflection when there's too much light coming from inside. It also seems like your images could be stacked in interesting ways to bring out the reflections even more.

I have heard that you can take 2 shots at about the human eye width of 2.5~3", having them completely facing straight and on the same level. So long as you do that, you can adjust what part of the image remains in "focus" in post. Is this true? I heard that a distance of 6" or so is good for longer shots according to this video, but just out of curiosity, what's the science behind it?

comparing the 70D to an R6 i miss the dedicated buttons like iso, focus mode and Slow-/ Hispeed shooting modes. Everything takes more button presses except video where i now can just press record instead of needing to switch to video mode - although being with automatic settings in non-fancy log. The video on Canons DSLRs always felt like upscaled to 1080p @ 30fps and now i get downsampled 4K 60 fps that is sooo crisp and feels like a huge technical leap for a canon camera in my price range. I just feel like the L lenses lost their glory. Being now made out of easily scratchable plastic and often having lost internal focus + zoom. Even worse that now everything is focus by wire which is not at the point where it feels natural and snappy enough for the times the much improved autofocus has troubles. The whole Lens design department seems to have lost their pride with RF and now you have prime lenses that wont work until extended and start at f/11, Lens elements out of plastic polymers where they previously boasted about being able to grow huge fluorite elements themselves. all while prices have shot up where it does not make sense for a hobbyist like me. But EF is fine for me, the EF lens adapter even allows for a single drop-in polarizer instead of buying different filter sizes or adapter rings for all my lenses.
@FilNennaАй бұрын
GREAT POINTS! I overlooked those top-plate buttons and I miss them, too. I've not got into RF lenses yet as I don't feel limited by using EF versions. Sad to hear they are more expensive but lower build quality. Hopefully the optical quality makes up for it?

@@FilNenna Thanks, a compliment that i'd like to give back. Megapixels and specs are important but everyone covers that. Your approach on the handling requires actual use and observation that i appreciate a lot. i did not realize that the tripod mount is shifted so far forward because of the mirrorless design. but i saw that my QR-Plate sticks out more than before. Same with the lens retraction. i did notice that upon shutdown it would focus to infinity but did not make the connection to lens retraction because i mostly own internally focusing ones.

Really interesting video, thanks. I've been using linear polarisers for a long while (they seemed to be much cheaper) and I had not noticed any problems on mirrorless cameras (older Sony and Fujifilm). My understanding was that the problem was with DSLRs where the the light is measured from the mirror reflection (and so messed up by linear but not circular). Looks like I'm maybe only half right?
@FilNennaАй бұрын
I noticed I had no problems when filming through the linear polarisers with my R5 or an old 40d. I was using short lenses with still subjects, so I wondered if it might be worse with telephotos and faster subjects. Perhaps linear polarizers aren't as tricky as they are made out to be?

Interesting yet complex subject. I've seen macro photographer's put polarising filters on their flashes along with one on their lens to control things like glare and reflections. Certainly it can solve problems that no amount of post processing in the likes of Photoshop could fix. I've personally only used circular polarisers on my lens to reduce reflections on water, windows and motor vehicles but clearly I've barely touched the surface of their capability 🙂

One small trick. You can go down to 1/13 handheld and still shoot sharp, if you set the shutter mode to timer and set it to 2 seconds. Most of the camerashake came from the pressing of the shutter button. With a timer set, you press the shutter, and after the movement when the camera still again, it will make the image. Not 100%, but approx 30-40% of the images will be sharp with this, if you practice.
@phenanritheАй бұрын
What the graph tells us is the amount of noise added after exposure, for each setting. Now, you have to balance that against the signal you're getting at each setting, i.e. would you benefit from the gain of brightening your picture with the ISO setting vs the noise it adds. It all boils down to SNR ration. Because of that, I don't think you'll find one unique ISO setting that fits all the situations.

Great video. Fil. Thanks. I've heard the R5 has no documented base ISO, though 800 and 3200 are often cited. Neither is especially supported by your results or the chart. The chart suggests 100 and 400 would be closer to base ISOs. Is base ISO even a thing, at least on the R5?
@FilNennaАй бұрын
The R5 has two stages; from 100 to 300-ish, and from 400 to maximum. In each stage, changing the ISO is similar to adjusting brightness in post. e.g if you brighten a shot at 400 by 5 stops in post it will have similar noise as a shot taken at 12800. Either way you look at it, we under exposed by 5 stops and have a similar noise penalty. I'm not sure how to word it, but the invariance means that there isn't a real base, though 100 is cleanest, and 400 is cleaner than 300. However one of the points in the video is that all of this is really in the weeds because the images are acceptably clean up to 1600 (or 2 stops of under exposure at 400) anyway.

This test lacks everything needed to call it a "test": the influence of the white balance of the light sources, the uniformity of their emitted light spectrum, the amount of light present in the scene. No reference to the operation of the conversion of the linear response curve of the sensor into the logarithmic one perceived by the human eye, the density of the shadows and the dynamic range, nor of the AI software for reducing the noise of the RAW file.

@@etniel7 I would love to see a world where only those who have truly committed to learning are teachers. And you would love to see a video with the correct information, whether it is mine or not, without having to navigate a sea of imprecise information. Or maybe a text instead of the video, like the following: Only those who have a specific purpose, such as large prints to be viewed up close or delivering a particular type of work with precise parameters to be respected as in astrophotography or art reproduction, really need correct information (or the enthusiasts of knowledge). The others can rely on more user-friendly tools, such as AI software for reducing noise on RAW files, and enjoy the passion for photography without wasting time looking for technical details without learning the basics. In the case of ISO, for example, what is called White Balance is actually the imbalance of the amplification of the individual RGB channels: in an environment illuminated by a "warm" light in which the exposure meter suggests an ISO value of 1600, the Blue ISO could be 3200, but also 6400 or higher, up to problematic cases such as for sodium vapor light sources in which the emitted spectrum does not include the "cold" frequencies. The "perceived noise" will always be that of the most underexposed and over-amplified channel. And the noise will always be higher in the shadows rather than in the highlights, because the signal recorded by the RGB sensors must be amplified (in greater quantities in the shadows and less in the highlights) to correspond to human perception which is much brighter in dark areas (perhaps for evolutionary reasons of need to see prey and predators in that shadows, but I am not an evolutionary biologist). This "perceptual difference" results in noise in Low-Key scenes that is 1 or 2 Stops higher than in High-Key scenes. I'll stop here for now, without talking about Baked In Noise Reduction, thermal noise and Black Frame or anything else, but I think that to invalidate the test in the video, it would have been enough to have had the good sense to consider "tests" only the verifications of a theory carried out in many more scenarios than just one. 4397 Views at this time

Wow, I'm shocked, to be honest. The curve looked absolutely reasonable to me, reflecting the old "1 / focal length" minimum shutter speed to hand-hold. Bang-on. And then it turns out that is with IBIS on??? If that is the case, then either the R5 IBIS is crap or something went wrong IMHO.

In essence your findings correlate with the standard reciprocal rule. Your 85mm lens was giving 60% hit rate at 1/60th but once you upped it one more stop to bring it over 1/85th ( in this case 1/125th ) you achieved 100% 🙂. I still apply the reciprocal rule irrespective of now having IBIS/Lens stabilization at my disposal. I'm aware that IBIS/Stabilization are good to have and will certainly yield sharp photos at what would have been impossible to hand hold but in the main I don't lean on its capabilities too much. I shoot mostly events so to be honest I'm usually shooting moving subjects which require shutter speeds that exceed my focal length anyway so I'm often well above the reciprocal rule during shooting. I just up my ISO to compensate in situations where a noisy sharp image is easier to fix in post than a blurry image. For all but the fastest motion photography ( sports, wildlife, BIF, etc ) you could essentially just leave your shutter permanently at 1/200th sec and use ISO/aperture to set exposure and almost never get a blurry photo! 😉
