Hi everyone, my D5100 finally come and I've been having a play around with it getting used to digital SLR's as this is the first time I've used one, I hope this is the right section for my question. I'll explain what I'd like to do and hopefully you guys will know the best way to go about it. I want to take two exposures of a waterfall one around 2 seconds with just the waterfall and surrounding scenery and one with a person in of a faster exposure (so I get the foamy look of the waterfall combined with a sharp image of a person). Is there a way to do this in camera (image overlay leaves as ghost of the person which isn't what I was after). Or would this have to be done with editing afterwards? How would you guys recommend going about this? Having great fun, annoying my family as for five days now I haven't put the camera down!! Thanks in advance
