. I edit all the time with a TIFF file. Specifically I either edit in LR on the TIFF after I receive it from Silver Efex (or Color Efex) or even more often I take the TIFF file from Color Efex into Silver Efex...via LR, over and over...hence my wonderful file that say Edit-Edit-Edit 3...,etc. I am rather obsessive about trying slight changes before I decide on anything... So anyhow that is not an issue for me. Neither is size.And once you've worked on it in Silver Efex and then hit "save", its fully cooked. You can't really go back in and edit what you've done except in VERY limited ways.
I just downloaded it and have played around a little. There are a LOT of controls with this version - its gonna take a while to get to know all of the little sub-sliders and what they do and when (and when NOT) to use them. They also don't have any IR presets, which is a drag because I found the IR presets in the last version good starting points for some shots. I'll have to try to recreate the settings and save them as my own presets. The funny thing is they warn you to back up all of your custom presets before uninstalling the old version. Which I did, including re-saved versions of the IR ones. But you CAN'T import them into the new version! Which makes sense given how many controls the new one has that the first didn't. But what was the point of saving them in the first place if you can't use them?
Should be fun once I get used to it...
