I need all my tiffs. I use tif files because they are uncompressed. I can have them to be default open on Sketchbook Pro for markups. Without messing with other formats.
From a quality point of view png is also fine for my needs. The problem is that PNG is an unlayered format. And tiff supports layers. Let me explain the workflow:
I take screen captures to file to a temporary folder. So I have screenshot01.tif, screenshot 02.tif, etc.
I have a master Indesign document, let’s call it Indesign_screenshots.indd. This document is multi-page and already has links to screenshot01.tif… all the way to #18.
After making news screenshots that overwrote the old ones in the folder, when I open the Indesign document my links will update. I change title blocks in the master and a few call-outs, text and I can export that entire thing as a package (Indesign file + all screenshots used in it)
When these screenshots are .tif I can open them in Sketchbook Pro and add sketched details, hand drawn notes, extra shading, even fake nice blends with the airbrush tool. I can keep those edits in separate layers in Sketchbook Pro. I can also do the same in Photoshop. Saving the file maintains the layers for later editing.
I close my tif files with layered updates and the links in my Indesign file update. I can continue to do this without ever having to relink a new screenshot. I can go back and replace a sketch note. Or paste a new screenshot from Rhino>clipboard as a layer and close again. Document updates.
In summary I need an image format that supports layers. And that both Sketchbook Pro and Photoshop can understand.
