Thanks (as always) for your helpful advice--this is an area where I've been experimenting but I prefer a systematic approach to things over which I have at least some control. I also edit on a Benq (PD3200U, which is supposedly factory-calibrated, and I hope that's sufficient) but its brightness control is expressed in percentage, which is currently set to 50, and I can't find any reference in the manual for adjusting color temperature in °K. I use sRGB mode for editing (I avoid Darkroom and certainly Low Blue Light). I don't have a hood, but I keep the shades closed. Although the blades are thick/opaque, there's always some light leakage as there are small gaps even when they're closed, so even with north-facing windows, the ambient level changes. I always have all of the room lights off when editing but there's obviously going to be some inconsistency with the perceived brightness of the image depending on the ambient light, but I don't want to keep adjusting the monitor based on that (especially on a partly cloudy day where the levels frequently change)! I also hadn't thought about changing settings based on what program(s) I'm using and hope that doesn't make a huge difference, as I often bounce back-and-forth between DxO PhotoLab 6 Elite (which offers their new Wide Gamut color space), Topaz (Photo AI or any of its individual components), various Nik plug-ins, and occasionally other programs (such as FlmPack or PaintShop Pro). I always use as close to a neutral grey background as the program supports (although Topaz seems to only offer a rather dark gray and I can't find any way to change that). In any case, it would obviously be impractical to keep changing the monitor to optimize it for each program. Every time I think I've got things reasonably figured out, you keep reminding me how many variables there are and how "haphazard" (lazy?) my process apparently is compared to yours! The learning curve never ends... I'd prefer to have a "scientifically accurate" set-up, but my prints generally appear very close to what I see on screen, so I'm inclined to adopt an "if it ain't broke, don't fix it" attitude, as long as the prints look good. In the interest of consistent results, the last step in my process is to always print from Epson Print Layout (and the curiously-named "Darker" default setting where applicable).

Astrophotography is mostly what I do. I use dedicated astrophotography cameras. I have not in 3 years of KZread videos and in the two paid for how to process astrophotography images in Pixinsight no one ever mentions you prints come back from the printer too dark or slightly different color because your screen is too bright and you need to calibrate your monitor. I wonder why but finding your channel is huge . Another great video.

Thanks. Astro images are very different from a colour management POV, since they are essentially synthetic (albeit based on 'real' photons!) My experience is not as large as I'd like [mainly doe to living in a big city] but astro software gives the impression of being much more 'engineering' driven and not looking at the same issues as when dealing with earth based photography in good light. That said the printing issues are very similar, so all the steps to take to get better prints should be applicable.

Hi Keith, I respect your knowledge and appreciate all you have said here. So here is my one follow up question. I really do not see a strong similarity between the Macro Print that appears on the right side of your computer and the same shot shown on your large computer screen. This all comes near the end of the video where you conclude how much alike these two shots appear. So for me I approve of all the work you did to set up such a reliable editing process. But I'm not seeing it on my computer. Thanks for your channel. je

But... From where I'm sitting, they actually do look rather closer in tonality than on the video. I suspect the lighting on the big print could be raised a bit. That said, I'm always astounded anything looks good on YT videos - I still personally dislike the medium ;-) However, even this match is vastly more than I'd normally expect between an image on a screen (not soft proofed) and a print, given the differences in tonal ranges.

Soft proofing is massively oversold as a fix it simply isn't.

I have the advantage of being able to black out my room. The windows have solid shutters on them [as usual in France] so I guess I must start blacked out and work out a small lamp that gives me a sight of my keyboard etc.without influencing the view of the screen. Would you recommend total darkness in a room for editing?

@KeithCooper

In general I'd recommend low light levels in the room, but not fully dark, due to glare issues. I'd light the room so that when facing the screen, it's the brightest thing I can see, and if I turn round and walk round the room, it's light enough not to walk into furniture... ;-)

Keith, thank you for the informative video. I have an inexpensive Eizo sRGB screen with shade, Colormunki Smile and attempted some calibration/profiling with DisplayCal. I work on scanned color negatives. I have found that editing for web (verification on phone, iPad etc) is indeed nicer at 6500K. If I want to order prints, based on your information, I should calibrate the warmed up monitor to 80-90cd brightness, 5500-6000K temperature, minimize ambient light and adapt eyes for a while before editing? I'm asking because I edited a few photos last night at D50 and today, with daytime D65 profile they look pretty dim and yellow, so I'm getting confused. Appreciate your insight.

@KeithCooper

Жыл бұрын

Personally I find editing at D50 quite tricky - it also depends on the colour management of your system and editing software. Anything connected with phones/tablets is a complete lottery from a colour management process so 6500/sRGB is a good way to go ;-) For print 6000K seems a good compromise, but... However, I also don't have any significant experience of print labs, so it's not something I've investigated in detail.

Great video, as always, Keith. One little question, somewhere recently, I was told to use a white background for editing . I was using medium gray, so I guess I'll I'll switch back to gray. I edit mostly B&W, but color too. Thanks, Ken.

Yes I get asked about white - it will encourage you to edit differently, which might help with some poorly set up systems.

@@KeithCooper Thanks for the video. As a consequence, I did some test prints to check out your points. To get them to match, I had to turn down my monitor even further than it was already turned down (to level 5 out of possible 100, previously 19, not a high end monitor). I also compared it the the photos I've mounted in frames with standard white mattings. For me, the on-screen image looks closer to the mounted image if I also use a white background rather than a grey background. Presumably it helps to match the mattings. Really thanks for the tips as I was previously using the standard black background and was often disappointed when compared to the print. On my little testing the new system works much better. 👍

Great explanation! I have one question though: would it be a good idea to have a separate monitor profile set to around 5000-5500K and use that profile when preparing files for print? That way one could use the standard 6500K profile for everyday things and not have to compromise.

@KeithCooper

Yes, a good suggestion... However, in practice I've found switching more trouble than it was worth, and that in fact I was able to print just fine from a 6500K monitor Ideally you need a monitor with two calibrations - I can do this with the BenQ monitors I use, but [currently] I still have to manually switch display profiles on my Mac as well.

@KeithCooper

Paper doesn't have a colour temperature as such... The colour of the paper [as found in the specs] can definitely influence how a print looks, but taking care in viewing lighting is a good step. Relying on soft proofing to get a feel for this can be problematic since it is very dependent on the quality of the profile creation process. In general this is one of those aspects where a good test print of a test image can help characterise a paper - actual measurements don't come into it for my own print making

Another reason for the popularity of dark mode and black backgrounds on mobile devices/laptops is to increase battery life.

Thanks - absolutely never occurred to me! Guess you can tell how much I use such devices ;-) Then again none of them could ever be seen as optimal for colour critical editing ;-)

I calibrated my monitor (acer B227U) with my Spyder x Elite, in a pitch dark room. It doesn't really make sense to do so, because when i did the test print, its impossible to compare the printout to the monitor. since you have to turn the light on and that skews the photo and makes the screen look very warm. I might have to run it again.

Hi I read somewhere that files types also have an impact on the print. Something about banding. But before spending money printing different files types and paper types using the same photo let me ask this. Is there a preferred file type to use when saving photos from Photohop? Also does color or black/white photos benefit from being saved in different files types. I saved the same photo, landscape picture during a medium sunny day with hills and trees as well as fields and sky, sky is about 20% of the picture. Using Epson SC-P900 printer and printed one copy on fine art paper with the corresponding ICC profile from a PNG file type and like the out come if this print. Anyway, I saved the same picture in four files as stated below but cannot see any difference what so ever on my monitor, calibrated Benq SW321C using in Epson print software.

As with most such things - the true answer is 'it depends' I save files with layers as.psd [or .psb] files - the key is to work in 16bit if you want to do anything much with the files. Some people use tiffs, but I rarely bother unless I'm using some other software which needs them. I don't use png files for anything but graphics in my web articles Saving as a full/high quality jpeg and printing it is usually OK, as long as you don't do any more editing before printing it.
