SavagePT Posted September 21, 2020 Share Posted September 21, 2020 (edited) I believe i encontered a bug in Affinity Photo. It happens both with Stable 1.8.5.703 and Beta 1.9.0.734. I can't find any logical explanation, so i'm assuming it's a bug. It always happens. I tried with various old photos and the results are always the same. The steps are as follow: 1- I scan an old photo with my scanner software, open the resulting jpeg file in Affinity Photo, crop it and covert the colorspace to ProPhoto RGB. 2- I click the auto-levels button on the top of the toolbar. I get a bad correction. 3- I undo the auto-levels and export to tiff. I reopen the image and click the auto-levels button on the top of the toolbar. I get a good correction. Also: 1- I scan an old photo with my scanner software. 2- Covert the photo to tiff and ProPhoto RGB using a Bath Job 3- Open the Photo, crop it and click the auto-levels button on the top of the toolbar. I get a bad correction. 3- I undo the auto-levels and export to tiff. I reopen the image and click the auto-levels button on the top of the toolbar. I get a good correction. I'm attaching a couple of examples. and 2 screenshots of my export tiff settings and my batch job tiff settings. I didn't change the resolution and i didn't do anything else to the files i attached. I'm also attaching one of the originals, directly from the scanner, if anyone wants to try.

Staff Gabe Posted September 25, 2020 Staff Share Posted September 25, 2020 Hi @SavagePT, Sorry for the delayed reply. This is not really a bug. Our crop tool is not destructive by default, so the cropped area is still accessible, unless you right click on the layer > rasterise and trim. So, if you don't trim it, it will auto-level the entire image, not just the cropped area. Quote Link to comment Share on other sites More sharing options...
