    Re: pinhole sharpness

    I haven't looked into it personally, but I'm sure there's also some way of knowing the image circle if you wanted to build a 6x6 roll film camera vs. 4x5 camera.

    Re: pinhole sharpness

    Not so sure about that. At f/45, f/64, f/90, there's a trade-off between depth of field increasing & sharpness decreasing due to the convergence of light waves. Pinholes aren't known for their...
  3. Re: A quick comparison of three 135mm 4x5 lenses

    Hi Howard. I've followed you for some time on Flickr, you're awesome.

    All I can add is that the Graflex Optar 135mm to me was a big let-down. I always hung around 35mm and 6x6 people in the late...

    I live in Dallas. I prefer to use filtered water instead of tap, especially for the developer. I just put my bottles in the fridge for 15 or 20 minutes and check the temperature. You will get finer...

    Re: pinhole sharpness

    Just to add my 2 cents. Finding a really slow film helps cut down on all the filters. Think copy film or inter-negative film, maybe even microfilm (but use a low contrast developer with the latter)....

    I wish Arista would better define their offerings. They've had hit & miss films over the years. A test run with a step wedge & densitometer never lies, but that doesn't help during the ordering...

    I don't think you should look for any one single development time. You are missing the point of large format. Roll film, you have to develop all shots on a roll the same way, but even then, I'll...

    Re: Fomapan 4x5 sheet film and Xtol

    You ought to use a step wedge, develop at different times then use a densitometer. I don't shoot any emulsion until I've tested it. After that, I know exactly how I want it exposed & developed.
