bbartlomiej Posted December 7, 2020 Share Posted December 7, 2020 Hi, in line with other editing software I'd like to have a way to import and export curves. I have some computed curves for digital negatives reversal and would like to import them into Affinity photo. Trying to match the shape of the curve does not provide proper results.

SantaFeCam Posted December 7, 2020 Share Posted December 7, 2020 I second this request. In order for a switch to Affinity Photo to be useful to me, I need the ability to import Photoshop .acv files that I've used for many years, as presets to be used in Affinity Photo.

PatrickMarq Posted January 10, 2021 Share Posted January 10, 2021 I support this also, as I need this also for my digital negatives SantaFeCam 1 Quote Link to comment Share on other sites More sharing options...
Ruzeen Posted January 10, 2021 Share Posted January 10, 2021 I would like this also. There's a few curve presets I use for astrophotography which I would like to poll over to Affinity Photo since I've finished my transition from Photoshop to Affinity.

John Rostron Posted January 11, 2021 Share Posted January 11, 2021 You can record a macro which will add a new Curves Layer, then adjust the parameters to you requirements.

John Thanks, but that's not what this is about. We want to be able to specify the curve manually in a text editor using numbers (as for PhotoShop, GIMP) and import this file in Affinity curves. I have computational curves I'd like to use. Others would also like to backup and restore curves. This feature is available in almost all editing software so would be nice to have it in Affinity as well.

Agreed...though for me, it wouldn’t just be nice, it’s necessary. I was supplied .acv curves for my work that took someone else hours to develop through printing trials. Much as I’d like to, it doesn’t make sense for me to switch to a software that requires all that work to be redone. Digital negatives require curves that aren’t based on the visual appearance of the image, but rather the amount of UV light blocked by the pigment printed at each pixel on the negative. So the curves must be specified using coordinates, and as bbartlomiej said, it doesn’t appear Affinity provides for that. bbartlomiej and antimattr 2 Quote Link to comment Share on other sites More sharing options...

I am working on a cyanotype process and need to import ACV curves and was really disappointed that it wasn't an option in Affinity. I am not sure what to do right now. I can delay my project for a while I guess, but if this isn't going to be added I need to find an alternative. Quote Link to comment Share on other sites More sharing options...
bbartlomiej Posted November 14, 2022 Author Share Posted November 14, 2022 Unfortunately v2 haven't brought any changes in this area. Affinity - kindly add this simple enhancement to the curves tool. Quote Link to comment Share on other sites More sharing options...
