    Re: Need densitometer reading

    Do you have a spot meter. Place the negative in question over your spotmeter's lens. Every 1/3 of a stop the spotmeter reading drops represents 0.1 log d. Or every stop represents 0.3 log d.

  4. Re: Should I get a center filter for my 65mm Nikon-SW f/4 & 90mm Sinaron-W f/6.8?

    I don't think you need complexity and expense of photoshop, during printing just burn the center with some cardboard.

    Re: Need Guidance on Getting a Sensitometer

    To plot the results from the sensitometer, you will need to know the values of the step wedge. Is it built-in to the 383? If so you will need to remove it to measure it with your densitometer. I had...

    Re: 8x10 Wide Angle Lenses for Still Life

    Less bellows draw can lead to less shake and it can be easier to work. In that case, just about any 210mm lens should work on 8x10 in close range. As you know the image circle increases with...

    Re: Need Guidance on Getting a Sensitometer

    LED sensitometers work fine for comparative testing most black and white panchromatic films. Analogy is a 'balance' where you have to place objects on both dishes to compare things.
