Photolab is good, except for these few things

Hi all, I’m brand new to DXO. I’m looking at it because like many others am a bit tired of Adobe subs. So far the trial has been decent, but coming from Lightroom I’ve found my Canon 5D images to be quite dark in comparison. Fuji files seem fine, but trying to get the exposure up on portraits has the skin tones washing out badly. Has anyone else seen this, and found a solid workflow to keep the skintones intact? I think I’ve somewhat handled it, but just wondering.

Also, sharpening on output is terrible. Things are either far too soft or far too sharp. Lightroom kills Photolab in this respect. It doesn’t matter what I do - if I export an image out at something like 1024 for the longest edge, Lightroom runs rings around Photolab. Anything I’m missing?

Which sharpening tool are you using?

In this forum, there’s a fairly long history of reported problems with Canon color rendering in PhotoLab. See here, for example:

It might help you to try different options for the Color Rendering adjustment palette, to see what produces the best results for portraits made with a Canon 5D. The default renderings you’re using are, as you say, too dark and not protecting the flesh tones properly. Fortunately or unfortunately, the options you have for color rendering are vast.

If you’re not already doing so, try experimenting with Smart Lighting adjustments, too.

Output sharpening complaints also go back a long way. You might want to look at the following feature request from 2020, which to date has accumulated 71 votes and many comments which might be helpful to you:

Hi Mark… (no The Room reference here :joy:) I’m not using a sharpening tool. It’s just the default screen sharpening in Lightroom. Are extra tools what people use in the DXO world?

Thanks for the link, Egregius. It took a while but using the colour profile for the camera I have, and using curves instead of the exposure slider or tone controls got me a better result than the result I quickly whipped up in Lightroom. So, that’s good! It’ll just be a longer process than a few clicks in Lightroom.

I tend to shoot Fuji these days so most of the time I shouldn’t have a problem.

Now if they can get a proper output sharpening algorithm, I’d be all set.

You can speed things up by creating a preset that can then be applied automatically on PL’s discovery of the image file. Read more about presets in the user guide that you can access through support.dxo.com.

Welcome to the DxO USER forum, @r10k

Note that it’s a new-PL-user misunderstanding to assume that you need to select the colour profile for the camera used to capture the image (referring here to the Type & Rendering options within the Color/B&W Rendering palette) …

  • PL will do this for you automatically when you select “Type” = Generic Rendering and “Rendering” = DxO Camera Profile

  • The purpose of the ability to select a specific Camera body is to allow you to override the “natural” rendering for the camera used to capture the image with the rendering typical for a different camera … such as when you have 2 different camera bodies and you wish to render all images the same way, regardless of the camera used.

Also try bilinear? Bicubic may softer, bicubic sharpen may too sharp.

Take a look at Topaz Photo. Sharpening, which includes several AI models to cater for different types of blur/softness…

Yep. PL bicubic sharp more ‘sharp’, may ‘oversharped’.


Left to right: PL bilinear, PL cubic, PL cubic sharp, Lr nosharp, Lr low screen sharp, Lr standard screen sharp.
For me, seems the main difference not really in Lr screen sharpening, but the resize itself. Note: Lr don’t have a control over that, but use bilinear, with auto settings - and not standard bilinear (but some tweaked)
Anyhow, a bit control over PL Bicubic sharp (sharp amount) can be nice. And Lanczos method, yep, its just do a balanced nice.

Thanks, yes… I should’ve mentioned I was aware you could do that. What I meant was more that LR has a number of automatic exposure options, and those speed up my workflow a lot. Tweaking from there is very fast, while I suspect in PL things will be slower going, even after applying a preset.

Ah, thankyou for confirming that! I had my suspicions, but good to know :blush:

As for sharpening, whatever option you choose in PL just can’t compare to LR. For now I’ll just use Affinity to batch resize using Lanczos.

Actually after a test I think LR is using lanczos for output screen sharpening…

Autoexposure is mostly managed by “Smart Lighting”.
The default value is a bit too much for my taste though.

There’s actually an even faster way to accomplish this:

Under Settings → General
Select the checkbox for “Automatically use camera rendering if supported”
