Interesting. Going to have to watch this again then experiment.
That’s really great learning, but does this work for printing an image too or only to view it on digital monitors
See gregbenzphotography.com/hdr/#printing
An excellent article as always Greg. Thank you!!!
Excellent as always, Sir!. Do you have any recommendations for HDR monitors, or can you point me in the right direction towards a good resource for such? I currently work on an M1 MBPro, but connect a monitor for desktop use.
I don’t have a list of specific models, but some general advice in my e-book (gregbenzphotography.com/hdr/), aim for 1000+ nits. Your MBP is 1600 and you’ll notice it’s much better than a 400-600 nit display. The quality of what Apple put into the latest MBP is unreal and there isn’t much like it at less than $2500 for an external monitor (ASUS ProArt worth a good look).
@@gregbenzphotography Thank you kindly! I've been a Lumenzia fan for some years now (v6 !!) and have gone through all of your online course material. The quality of everything is top notch, and it has really helped uncover some of the more nuance details of Photoshop. Thank you!
Thank you!
Can you recommend a 4K thirty-ish inch (30-32) monitor that’s suitable for photo editing (reasonably large gamut) and is HDR capable? My older NEC PA302W has a large gamut, but miserably fails your HDR test. My 14” MBP and 12.9” iPad pass your HDR test, but are simply too small. Any suggestions would be most appreciated. Thanks, Stephen
I just created a page with my thoughts on various HDR monitor options: gregbenzphotography.com/review-best-hdr-monitor-for-photography/
Please let me know if you have any more questions or feedback.
This is probably a dumb question, but when you process in 32bit when you print, do you get 32bit? Second question, what printer would print 32bit?
Great question, please see gregbenzphotography.com/hdr/#printing
I have a question, how can I convert a 8bit 360 image to a 32 bit HDRI map that I can use for lighting 3D models? Can you please guide me?
Please email me to discuss in greater detail. gregbenzphotography.com/contact/
Excellent but you can't print these so whats the point ?
Same as sharing any image online. The print is never identical and it’s easy to manage both HDR and print: gregbenzphotography.com/hdr#printing
Hmm?? Is YT's Tonemapig like contrast biased or better than PS? I mean as you said and shown you maxed out (or close to maxed out with 254) the max brightness of 16 bit SDR. Yet when you made the adjustments I could clearly see the sun getting brighter.. on an SDR (or not even that) Display... Unless my brain made a wrong turn somewhere I can only assume that this Tonemapping in the vid is tricking me by making the surrounding darker instead of the target brighter... which it shouldn't be able to do... should it. Though it didnt looked like that.
Never the less... Thank you for the Update!
P.S. That reminds me...need to check if HDR Pro (Merge) in PS can now FINALLY export to 32-bit... instead of having to tonemap in ACR and end up with a 16-bit.
Yeah, the tone mapping is quite good in YT and Chrome.
You can open those HDR images as 32-bit now
Greg, now that we can re-process our photos into 32bit HDR photos - how can we best go about showcasing them in a slideshow on an Apple TV hooked up to say a 65" LG OLED? I use that setup for watching stunning HDR movies all the time in HDR10+, DV, etc. I have no idea what format, app or system to use to get these beautiful 32bit HDR photos running in a slideshow on a HDR TV. Do you have any suggestions or tips? Love the video.
See my e-book for lots of detail gregbenzphotography.com/hdr/
Use an HDMI cable, enable HDR in the display settings on both computer and TV, and make sure to use the best input as not all TV ports support best quality.
I’m not aware of a way to use the ATV itself for this yet, but haven’t looked. AirPlay2 does not work.
@@gregbenzphotography Thank you again! I hope someone makes an Apple TV Photo slideshow app that will support this in the future. Or maybe Apple add support to these files so we can use the default slideshow to get HDR viewing.
I am sure there are a lot of people out there now with huge libraries of photos in RAW or TIFF like Lightroom or folders - who after this video started using Lumenzia v11 and finally got some amazing display results from their photos. But manually doing this one by one is very time consuming. Do you think its possible in the future that there will options with Lumenzia to batch develop large quantities of raw or Tiffs and/or lightroom integration/export to do this? I have thousands of “exported” photos that I would now like to “redo” from Lightroom. I know I could potentially clip some without the finer granular control you do, but with a slightly less strong effect one might avoid that altogether? This video your knowledge and Lumenzia v11 is opening a new dimension of Photography/display. Incredibly amazing work, so thank you again!
HEIC might work, that’s supported as HDR in Photos on the desktop now. I haven’t tried converted and showing on ATV. Given that’s a hassle, surely most would wait for more broad support, but there’s a good chance your phone images work there now (as they support HDR HEIC now).
Web Sharp Pro can batch process 32-but images to TIF, which you can then batch convert to JXL via ACR. If PS adds native support for these file types (AVIF / JXL), I would add direct support in Web Sharp Pro gregbenzphotography.com/web-sharp-pro-panel
The “Map” feature in Lumenzia would help avoid clipping. You could go beyond that even. When you open an HDR image in PS, it might clip if processed too bright. But a web browser will tone map and so the limit for clipping is higher than where you’d see clipping in PS. It’s pretty forgiving.
So my question as I am a print guy. Does this have any relevance in print? Or only for HDR monitor displays?
Please see gregbenzphotography.com/hdr/#printing
With the M1 Chip, i am having issue installing Lumenzia, is there another way around or is apple going to fix this issue?
No issue, works natively on M1. Email me for support.
after it goes back to Lightroom, what happen to the display and then the print ( as a JEPG)

LR will show the image, so you can manage the assets normally. But the preview is not correct as this tech preview is only in ACR at this time. I’ve got notes about it in my e-book on my site. It’s not ideal, but totally fine.
JPG is not the right file format for HDR, FYI. AVIF or JXL is the key.
What is happening if you were to view this image in a non HDR monitor, or export the image into a JPEG for web ? Would the sun be clipped like in the layers ? Thanks!
It will render fine on an SDR monitor, it just doesn’t look as good. See gregbenzphotography.com/hdr/ on different monitors and it will be clear.
You need to export as a new file type, AVIF.
@@gregbenzphotography thanks a lot :-)
I was interested about exporting a 32 Bit image for internet use. Trying to do this from the 32 file caused banding and a loss of brightness. Merging the 32 and returning it to 16 bit allow a much 'brighter' and band free .jpg conversion. Of course it will only register 255 so it is only an impression but it does allow pushing the whites much more without burnout/banding...though how it looks to others and their devices is another question! 😁 [edit: The original was only an 8 bit .tif from an iPhone so this may have effected the original's manipulation problems]
Export as JXL or AVIF and there is no loss.
Try using ACR for conversation from 32 to 16-bits.
I’m not sure what you mean by banding. Compressing tonal range (HDR to SDR) should not cause banding. I’d wonder about false banding or other issues. Would need to see the before and after image.
@@gregbenzphotography Perhaps it was the wrong choice of words. The original 8 bit image was over exposed around a very intense light source (like shooting in to the sun). The gradient of decreasing light values were apparent in banded steps. These started smooth in 16 and disappear in 32 bit. It was probably a poor example to discuss given it's low bit rate origin!
Could be. Certainly banding is a risk with an 8-bit image getting expanded into HDR, I just haven’t seen it yet.
