Originally posted by swanlefitte Found objects as in isolation or as where they are found? If objects tend to be square or round a square frame is good. If objects tend to be more rectangular then a square will squeeze the framing. If you need environment in the frame to show where found, a wider frame is more helpful. That said, if the collection is going to be like a book, I would probably use 4x5 or 5x4 depending on if the short or long side would be the binding.
For this project, I am going into antique shops and thrift stores to find something out of the norm, so I am "finding them" and bringing them home or to an interesting location to photograph. My finds in the last week were:
A General Electric PR-1 Exposure Meter with tan case in mint condition for $10 CAD *introduced in 1948)
An old metal canteen with patterned wool covering for $5 CAD.
A Canon TX film camera with 50 mm 1.8 lens for $20 CAD
With this project, the photos will probably be done in B & W. I have tried cropping previous images to 1:1 and liked what resulted in many cases. The problem is, using a 1:1 ratio places equal weighting on every part of the image. Composition becomes quite important, if using a 1:1 ratio in the camera itself, but if you keep the default 3:2 setting and crop it later in post-production things often work out okay. The potential problem is that by discarding at least 1/3 of my digital image, I am cutting the usable pixels down to just over 10 MP. That's okay for an 8" square print, but you can't push things too much further without losing details.
I will say this much: If you really want to focus on image composition, cropping to a 1:1 ratio will really help...
