These files can be included in Lightroom or Photoshop after downloading.
Right-click on the file and select "Install Profile" from the drop-down menu. Then you can select this profile in Photoshop and Lightroom.
With ICC profiles it is therefore possible to see what the printed image looks like later. It's called "softproof".
In addition, a color perimeter warning can be activated. In this mode, Photoshop identifies all gray colors that cannot be printed. When printing, simply take the next similar color. Normally, these differences should be so small that they will not be recognized at all. If only very few parts of the picture are affected, you can ignore this. Nevertheless, it is advisable to switch on this "color perimeter warning" to get an overview. Printers sometimes have problems with very intense, bright colours.
For large areas in the picture you should try to reduce the colors a little bit with the "dodger tool" or to reduce the contrast a little bit.
After editing both photos are now identical again. So we "compensated" the difference. When hiding the ICC profile (using the CTRL+Y key combination), the softproof image now looks more saturated and more contrasting.
Now saves the image as "DSC_7474_Softproof. jpg". Now you can upload this file to "Saal Digital" and have it printed as "Photo print on acrylic glass". It will then look exactly like the unprocessed original.
If you want to have a different creation, you will have to repeat the whole procedure with the softproof from the beginning.
This procedure must be repeated for each picture, because each photo is individual. There are no ready-made settings or actions for Photoshop that can be repeated with every photo.
This all looks very much at first glance, but once you get the hang of it, it doesn't take long. In any case you will have a work on your wall, which corresponds exactly to your ideas.
Of course you can also use this procedure for other works and photo books. I hope I was able to shed some light on the different ICC profiles and color spaces.
