# Keeping old renders open [duplicate]

I'm trying to learn materials, and there are so many options! I'd like to be able to compare side by side the effect of changing certain values.

Is it possible to keep old renders open?

• What do you mean by old renders, the last rendered image and so forth etc? Possible duplicate of Logging Renders – iKlsR Jul 13 '13 at 2:53
• That's what I mean, yes. There doesn't seem to be a way to view two different slots at the same time, however. – ajwood Jul 13 '13 at 2:55
• Cant you create more views? Closing as a dupe. – iKlsR Jul 13 '13 at 2:55
• Changing the slot on one view updates all of the other views to the same slot! – ajwood Jul 13 '13 at 2:57
• possibly.. :) I usually just cycle through these quickly using shortcuts, Alt + J and J.. – iKlsR Jul 13 '13 at 3:09
