Thanks for the replies. Lightroom is only relevant to very superficial retouching, but let's say you bring several JPEGs into a Photoshop document, convert them to smart objects, duplicate, flip, rotate, and warp them? If you save this as a Photoshop file, the file is huge. But if all the original JPEGs were retained as JPEGs, the file size would only be a little larger than the original files. It's a much more efficient way of storing the images. You suggested saving it as a zipped TIFF. Not only is this slow, but it only brings the size down from 66 megs to 50. Not very efficient, and you're needlessly converting a lossy file to raster data, then re-compressing it losslessly. If all the original images stayed as JPEGs, there's no wasted file space! Which version do I use? CC 2015. To explain why... I don't believe "newer" is necessarily better. New versions bring whole new bugs and troubles, and lately Adobe has been tending toward making its products uglier and darker, with light text on dark backgrounds, hideous splash screens, and horrors like the new "New Document" dialog. It really puts me off. There's also the ever-increasing sense of "bloat". 2015 opens really fast. But I have actually tried CC 2018 and it took way longer to open. 2015 just works great for me and does all I need it to do. I will update if a feature gets added that I think may be useful. But that hasn't happened for a long time now. The 10 Photoshop improvements I'm still waiting for are... Smart Masks Proper custom shortcuts (like with all Adobe's other applications) Ability to launch the program quickly without it spinning up every hard drive on the machine
Small tool to show the current foreground/background color (ideally on the control panel)
Way better scrolling while dragging (scrolling should speed up the nearer you go to the edge)
Fractal-based upsampling tool (similar to Photozoom Pro) Custom interpolation mode for smart objects Much lighter interface colors, like classic Photoshop (new versions are so gloomy!)
Custom splash screens Fix the bug which shows 16-bit documents in only 8-bit when zoomed out beyond 66.67%. (This.)
