  1. Re: Is it a linear progression between 90mm and 150mm?

    This is incorrect. Perspective is only changed by positioning of the camera. This misconception comes from the inherent moving of the camera when switching lenses to match framing/composition of the...

    Re: Looking for feedback on images...

    I only have one suggestion: GET CLOSER!

    "If your pictures aren't good enough, you aren't close enough” - Robert Capa

    This is the single most important tip when shooting with a 90mm lens IMO.

    Re: Pinhole Technique and ULF

    Looks good Randy! What was the pinhole size?

    I've been wanting to try pinhole for extreme wide-angle on ULF. My one try resulted in underexposure because I calculated something wrong. I would want...

    I also shot this on Efke which retained highlight detail, but I'm not sure that is really a necessary thing for this image. Thoughts? Here's the Efke shot, and a slightly tighter crop:

    Yeah it was interesting, the line of cypress was in about an inch of water, with some high spots of sand and bivalve shells. Exposure was about 1/4 second IIRC and I waited till a wave broke over the...

    Yes that is what I said Drew. I believe the confusion comes from the fact that most people have experience with 35mm (or 120) SLRs or modern DSLRs and there are not center filters for those lenses...

    No they don't, if we are talking about modern retrofocus designs. Sure, the 21mm Biogon for Contax 35mm rangefinder has the same basic fall-off characteristics of the 75mm Biogon on 4x5, but the...

    Dan, don't most modern wide-angles use the tilting pupil design? Glancing at a couple of my lenses, they all seem to have it to an extent (compared to my actual 75mm Biogon).

    Of course they exist for a reason. And of course one should use them if they are really, really worried about even illumination.
