No this isn't a troll, however it is a serious post. Like many photographers, or it may just be me, the image I sometimes see in the viewfinder/screen is not quite what I remember the scene to be. My wife has a Canon A310 - a digital equivalent of an instamatic which I have started carrying to "proof" sites prior to photographing them on film. The advantages I have found are as follows.  Quick walk around the area -- just shoot anything that is interesting.  Quick transfer into the GIMP and reduction to greyscale with a preset black and white filter to approximate the film paper look I have. The reduction to greyscale is very handy as it helps understand the scene in a B&W way. and  the ability to crop and examine image alternatives within things that have caught my eye. Something else that I have found useful is the fact I can look at the image on the computer devoid of the distractions of ambient noise, smells and other sensory input. I have often been dissappointed with an image because it failed to convey all the emotions of the location. I don't get this naturally when viewing another photographers work of course and "proofing" in this manner away from the location I can look more at the image for what it is not what I felt at the time. My wife has had this camera for quite awhile now and it has had little use -- until now.
