Re: [darktable-user] Dark photos when printed
Good suggestion. Another thing I do is during my edit, make sure I am really pushing the histogram, and I push the brightness a little more agressively with the tone curve than I would otherwise. Just to make sure a good amount of the brightest tones are really bright. Usually it works quite well that way. Jason On 2021-03-06 4:55 p.m., Terry Pinfold wrote: > issue with Lightroom.

Re: [darktable-user] Dark photos when printed
The problem of printed photographs being darker than what we see on the computer screen is a problem shared by all editing programs. The issue lies in the fact that our screens are artificially bright because we like them that way. Others have made good suggestions here including calibrating the monitor and installing printer profiles. I just wanted to reinforce that Darktable is not the problem here. I have had the same issue with Lightroom. The answer is calibration and also checking the look of the image on the printing labs monitors if possible. Many consumer labs have printing kiosks. Professional labs will usually provide printing profiles and provide excellent advice to give you great prints going forward. Personally, I print at home and use the printer's software to tweak my prints to match my computer screen as close as is reasonable. I also like to toggle on the ISO 12646 color assessment conditions option in the darkroom view when doing my critical exposure adjustments such as filmic. This colour assessment condition places a white border around the image and helps the user a lot with getting correct adjustments of the highlights so they are not too bright. Another great Darktable feature that ensures I get good edits.

As to the original printing problem: you can put printer profiles in your output colour profile directory, and soft-proof against them (https://www.darktable.org/usermanual/en/module-reference/utility-modules/darkroom/soft-proof/). Some profiles are here: https://www.fujifilm.eu/eu/support/photofinishing/color-management. Maybe you can compare if one of them, used in soft-proof mode, matches relatively well what you see on the print. Professional labs will also provide you with their profile, I think (I don't print). A search on https://discuss.pixls.us/ may bring relevant hits as well (and it's probably a good idea to register there, as sharing files and screenshots is much easier than on this list).

When you develop your photos, if you use a dark darktable theme, they will appear brighter than when printed (or shown on a lighter background). Plus, now we have an option to provide a more consistent viewing experience.

Re: [darktable-user] Dark photos when printed
Hi, Niranjan! 1. Without calibrating of your workflow is hard, almost impossible, to help. 2. Calibrating your monitor is a "must do". Some monitors come pretty close to sRGB (at least I don't see HUGE improvement after calibrating them), professional have wider gamut and most laptops are shipped with some sort of display profile of unknown quality (which is lost after OS reinstallation). 3. Printers are even trickier. They are to be calibrated for every paper type you use. My own personal preference - turboprint commercial driver. It comes with good quality profiles (at least I didn't manage to get anything substantially better) but equipment support is limited. 4. Color proofing workflow is something many users forget and I don't remember any darktable specific videos about it. If you don't proof your edits against your printer's profile then you will get gamut mapping of some sorts which translates into problems like uniform dark blobs or lack of details in lights (but darkening is the most common).

[darktable-user] Dark photos when printed
Greetings, darktable 2.4.1, Ubuntu 20.04 I am just a beginner and first time I tried printing some of photos I had. Commercial service from typical drug store on the corner where you can upload photos for printing was used. No calibration of my monitor or anything except tinkering with few styles until preview and exported image was acceptable. After printing, photos look little dark - not too dark, but not as bright as they show up on my monitor. Most of the photos were captured on sunny day outside. I am trying to learn why this can be happening. It could be my laptop monitor which is showing brighter than it should be or printing service could be processing uploaded jpeg image. Any thoughts or hints? Should I be tinkering with any other settings such as color profiles so that photos don't look dark.
