The Secret to High Detailed Photography

[@hallenw]

Years ago, I founded a photo group through a local art center. At one of the meetings, I challenged the group to do true black and white, as close as possible. I heard a lot of groans. So, I offered a 16x20 gallery wrap print paid from my own wallet to the winner as judged by me. When I reviewed all of the entrances, one really stunned me. The submission was done by an inexperienced lady who was just learning photography. When I brought the print to present the winner… a collective gasp followed by silence and then standing applause. The moral of this story is to go beyond what you think you can do and stretch your imagination. And that’s how I view your work and your commitment to DO and stretch your abilities.

Thanks for the informative video! Part of this process is to have a computer and monitor that supports 10 bit per channel colour output, and wide colour gamet. Not all monitors are created equal. You need a graphics card that supports 10 bit output over display port. And a monitor that can output nearly 100% or at least 97% Adobe RGB - Eizo, Dell, NEC and Ben Q all have options. No monitor, from the last time I researched can output ProPhoto RGB colour space. A classic example of this as you said is “ pushing” greys or skies too much and producing banding (loosing file information). This can be clearly seen on this type of system. I too agree, forgetting to reset Photoshop working colour space after an update has caught me a few times also.

[@stevepower9570]

joel, good stuff, i have shot hdr for more than ten years and like you nearly all that i do is hdr or suedo hdr. yes, hdr has been given a bad wrap until the viewer sees the light, and the light is the bit depth, and the detail in the shadows. great topic, StevePower

[@barryashenhurst2071]

Ah sorry Joel. What I actually meant to ask was which metering mode do you use in your Canon: evaluative, partial, or do you spot meter with a handheld? I'd also be interested to know how you sharpen.

[@CarmineGroe]

Thanks for the presentation Joel! Important information for maximizing the technical quality of digital capture. The sRGB colour space has a "reduced colour gamut" compared to Adobe RGB or ProPhoto RGB, as you mention. Important for all to know: colour information is compressed and lost or thrown away, not only by the bit depth option but also by the colour space selection when generating an image from a Camera RAW file (14bit or true 16bit MF capture ). sRGB is best for digital presentation; monitors, the web etc. Adobe or ProPhoto RGB is best for print purposes. With my 25+ years of pre-press and imaging experience, I've learned a couple things about maximizing images and processing and was fortunate enough to study under Dan Margulis, the ultimate master of colour and imaging quality who I'm sure you're familiar with :)

[@drte.alisson]

tks to explanation shared! I had thinking about if sRGB or Adobe RGB is the best colour space to use when I was watching another tutorial about it.

[@mondujar279]

I’m very interested in getting the highest quality possible. I am no professional but I enjoy my photography. Thanks for the advice here, I was aware of 32bit depth but now I will use it more.

[@Luigi13]

This is very good? As you explain the bit depth on this video I have been thinking on some of the prints I made and I only have two of them of a cityscape and they where printed after I requested to use my TIFF files at 16bit and not a JPG. Each time I look at the Tiff file prints I notice a richness in colors and a clear definition on the lines of buildings and smoothness of sky and, light and shadows. Definitely your last comment about printing it at a higher bits. I see the difference and it is also noticeable when I look at a Tiff file on the screen vs a JPG file. Very good information and definitely important to pay close attention to these. Thank you.

There are so many comments here that I did not check whether somebody already pointed this out: with 32 bit you get 4 294 967 295 color values per channel! 16.7 million values/channel is with 24 bit processing. Furthermore I don't remember if you mentioned that posting anything on social media or on the web in general it is usually converted to an 8bit jpg. Still when processed from 16 (14) bit bracketed raw files in Lightroom the final image will look better. Apart from these minor deficiencies I loved your presentation. And your photos are fantastic.

Excellent video and beautifully images. The way I see it is that the key is exposure. Each time you overexpose each time you make low values come out of the noise. Each time you under expose each time you allow high values to come under saturation. Though having 18 or more stops-dynamic range and compressing it in 8 bits is a pity given our monitors and prints outputs 😕

Thank you for the well-explained information. Question about bit-depth and dynamic range. I have an older Leica monochrom with a bit-depth of 14 but the dynamic range is only 8.5. So if I bracket 3 exposures +/- 2 and combine them in Photoshop with 14/16 bit will I have more information than say a newer M246 with its 12-bit?

[@dotdigital]

Joel, excellent tutorial. I have one question for you. In working /adjusting in the 32 bit environment within LR, Is the final saved image as 16 bit or 32 bit ? My reason for asking is this, I make large prints on an Epson SC P-8000 44" printer, similar to your own Canon ipf4000. These printers can work with 16 bit files but not 32 bit. As such I believe once you send a file to the printer the very best output you ll get is 16 bit. Are you then diminishing any of the 32 bit quality you worked in on the software? I was hoping you might explain this out for me. Thanks! -Paul.

[@garykanston]

Thank you for the information Joel. I have the same question as some of the other folks here - I do not see the video you mention about processing 32 bit.

[@gordonneedham7014]

One more Question ref HDR Panorama ... When you take 3 groups of 3 frames (9 Images) do you recommend using all 9 photos in Lightroom using "HDR Panorama" or do the groups individually and then take the 3 HDR images and merge them next?

[@joelgrimes]

there is no one-size-fits-all. I've developed my own process but whatever gets you the result you want in the least amount of time!

[@drewwenger4195]

I've done HDRs on landscapes or still life... What I don't understand is how you do make multiple exposures for an HDR on a portrait like the Harley dude... Do you tell him to stay absolutely still? how do you achieve 32 bits when your subject is animate.

[@TracyHoexter]

I wondered the same...

[@gregostudio]

Yes. Stay still, also photoshop will realign sutle misalingments between shots

[@joelgrimes]

I bracket with my ISO. To do that, I use the CamRanger, a device that connects to my camera. It fires the flash and camera fast enough to capture most subjects. Yes, they have to stay fairly still. I photographed around 100 Harley Davidson rider portraits and only one had some issues, which i fixed in Photoshop. This system works for me.

[@blackice5649]

Joel - Awesome video! I can honestly say that I learned something new about HDR. So question for you - to acheive the same effect as taking 3 pictures with different exposures - could I go back to an old photo and create virtual copies in Lightroom, assign different exposure to those copies, and then process in Photoshop like you describe?

[@joelgrimes]

I've not thought about this, I don't know if you can get that extra dynamic range without it being captured in the first place. I'll have to give it a try

[@simonvanderheijden432]

I'm a bit (no pun intended) new at this and there's something I don't understand. I understand the HDR process when you take 3 photo's set at different exposures (underexposed, normal exposure and overexposed) and you merge them in Photoshop to get an HDR image. This is relatively easy to do with architecture and landscape photography when the subject isn't moving. But how do I achieve this in portret photography? Do I tell my model to keep still while I adjust the exposure time or do I use bracketing? 'Cause when the model moves you're screwed, right? Any help and/or tips would be greatly appreciated.

[@joelgrimes]

Most cameras can fire these off pretty quickly these days. A bit of movement can be handled in Photoshop later. Sometimes obviously it's just not possible. But I love the restuls!

Where was your vid that showed how you used a grey backdrop with blend modes to change background. I mean I already know a little about using overlay with grey, but I think you can even use blend ifs to refine. I just wanted to rewatch that segment of yours to refresh memory on your method.

[@bkc1965]

Very informative video. I like to think about bit depth in terms of sculpting a statue out of marble...or even carving a figure out of a piece of wood. You need a very large chunk of marble (32 bit depth) in order to be able to chip away (process) at it until you are left with your desired final product. If the starting piece (capture file) is too small (8 bit) then after chipping away at it you might end up with a statue that doesn't have a nose.....clipped in a way.

[@elusivelens1744]

So, when you make prints after you've processed the RAW files, do you print from PNGs, for higher quality, or JPGs, for size?

[@joelgrimes]

It depends on the size of the print. a jpeg is fine for something small but the bigger prints would need tiffs of PSBs. testing or chatting with the lab is 100% recommended

I also had the chance to test the GFX models of Fuji. The GFX has 16 bit RAF raw files (Bayer layer) and is awesome in keeping details in the shadows. Nikon next best. My OM-D EM1 Mk III is the opposite, I can easily overexpose by 1 to 1.7 stops and the detail recovery pushing the highlight slider to the left side is awesome, but I get noisy results trying to recover more than 1.3..1.7 stops underexposed.

@@joelgrimes I've tested many HDR options too, I shoot a lot of HDR panos, you may perceive some advantage due to averaging of the composite frames but in essence it won't provide the advantage that actually varying the EV does between source frames.

[@youms237]

@@joelgrimes could you please share which ISO value represents under, normal and over exposed? Never heard of ISO bracketing before.

[@380stroker]

If you bracket the ISO what you are doing is adjusting your analog to digital converter's "gain". The more gain, the more noise. Just like music recording. Just trying to put things into perspective. Many modern cameras have good analog to digital converters which work well when the gain (iso) is pushed so that noise is virtually non existent.

Thanks Wesley, Keep in mind, it's not some much the viewing experience that we are effecting, but the ability to increase our detail in the highlights and Shadows.

Have a question about capture. Most of today's high end cameras are ISO invariant, so would you need to actually open up the aperture or use a slower shutter speed to capture your brackets? It seems that simply adjusting the ISO would not work.

I use both the Shutter Speed and ISO for my HDR bracketing. For me, ISO has been working amazing.

[@stevenk3699]

@@joelgrimes Ok, thanks, what camera do you use, I know using a Nikon D850 raw files, ISO changes just diminish dynamic range as you increase ISO, so I guess the reason it works is that allows you to fill up the 32 bit intermediate file from top to bottom, and preserving the data during level changes rather than increasing the captured dynamic range.
