I would love to be able to edit color channels

[npaust]

I use desktop design software mostly for my astronomical work creating color images of objects.  The standard astronomical format is a .fits file which typically contains a 16-bit greyscale image.  To create a color image, you take pictures with three different filters and then paste the greyscale images into the RGB channels in your colorized image.  After that, you typically have to offset the different channels by a few pixels relative to each other to get the objects aligned.

 

If Affinity could do that, I'd buy it immediately!

npaust, this is a feature for a pixel-based app. While Affinity is vector-based. I did not think about your idea but think this could be perfectly realized with photoshop or another imageeditor. And automated by a small script or action.

Hi,

 

Sounds like you would be better served with Affinity Photo - which is going into beta as soon as Affinity Designer is released - allowing channel-based raster editing.

 

I will investigate these ".fits" files - we pride ourselves on comprehensive import capability and if importing these files would be of use to people, I will consider implementing it.

 

Thanks,

As a workaround for now, if you use the "Place" capability of Affinity designer to place your individual greyscale images, you will be able to recolour each image (as Red, Green, Blue) using the colour page - then use the transform page to align your images.

 

Thanks,
