Huge TIF photos when using Lightroom & Photoshop to edit RAWs?
I have a glitch in my workflow that slows me down a little. I am certain that I just need to change the setting in LR. I'm looking for advice on the best settings for what i'm trying to do.
I post a lot of my work in Instagram. I have steps in my Lightroom workflow to ID the photos I want to use there. I open them in PS from LR to crop them into square prints the way I want them. I take a RAW image, open in PS, crop it, then save it back to my LR catalog. Issue: PS creates a 200+ MB file every time i do this! What's worse, is that I then need to use my preset to export it for IG (watermark, sizing, etc) and it creates a 500-800k file that I can easily post. So i have this temporary giant file that slows everything down. I go back and remove the mega-files from my catalog, because i don't need them - but damn, they take up room and it seems silly.
My question: How can I have PS create a more reasonably sized photo automatically. I could resize them in PS, but it's just a prep file and I don't want to do it for every photo I plan to share. Currently, LRs external file handling is: TIF, 16bit, 240 resolution...
I just don't see how a 50MB RAW file becomes a 250MB behemoth...
Any advice would be appreciated. Thanks.
PS I know that IG allows for non-square prints and also that LR crops. Neither of those work for what I like to do.
