Auto levels feature

[vedobel680]

Hello,

I'm using Affinity Photo for some time now and it's a great software but I noticed something strange in the behavior of the auto levels feature.
When applying auto levels on the picture below the results compared to Photoshop are completely different (the first is auto levels from Affinity, the second is the original and the last one is auto levels from Photoshop).
I started to experiment on other photos that I have and noticed that in ~80% of the cases the auto levels in Photoshop produce better result.
Obviously I don't except the results to be the same as the algorithms are probably different, but in this case the difference is too drastic (and possibly even worse).

For the last few months I'm using Affinity Photo only and I think that it replaced Photoshop for me, but this one feature is really missing.

Is there is some way to tweak the auto levels behavior to be more like in Photoshop? maybe some plugin?

Thanks.

Welcome to the forum @vedobel680

There is no way to edit auto levels, it appears to function differently than Adobe Photoshop CC version, or, Photoshop has some restraint over that of Affinity Photos Auto levels.

Affinity Photos auto levels appears to work on each of the RGB curves and trying to correct the compressed ranges but Photoshops auto levels seems, in this instance, to work on the master option only by nudging black levels in by roughly 10% and white levels in by 10% as it relates to Affinity Photos auto levels.
