The idea is to shoot one camera/one lens and show the best 1/3rd of your shots. Typically, when I have done it elsewhere, its been implied that you would be shooting 1 film in that time, so 1/3rd of a 36 roll film is 12 frames. For a forum such as this, it might not be fair to impose a 1 roll limit, so maybe your 12 best shots.
The whole idea of such a challenge, is to get people out there regularly shooting and having fun.
Look, I might be being a prick here, but if you don't want to view so many shots and don't want to feel like you are being a point and spray shooter by showing maybe some average images, simple, say thanks, but no thanks. It does appear that this doesn't have a wide appeal to this community, hence my comment two posts above, but if we get a handful of members who do want to give it a crack (say 5 members), then we can draw up some guidelines (based on 1 prime/1 camera/1 month/12 posted images) and go for it.
