Working Questions

[ArtistBob]

Dear Key Shot members;
I would like to know a couple of things about typical procedures. When making changes on any images and while waiting for 'screen builds' (pixel adjustment placements) do you have to wait for it to finish before asking for a screen capture or starting a render process? I think of a screen capture as getting a 'snapshot' at the time of what you see on the monitor which would not be at its full clarity and resolution. I'm curious what is the ballpark percentage (visual difference) between a Screen Capture and a full Render?, say for instance when you zoom in (looking at the "jaggies") on an image after it's done?
Is there a way you can render just JPEG, PNG, PSD, TIF's etc. and if so how? Since it seems that KeyShot is a very good render program, it seems a shame that you couldn't be able to enhance previous file images.
Thank you for your time and insight on these subjects,
