  1. Re: How do you see and appreciate a large format Portrait?

    I don't follow portraiture, I think the 20x24 Polaroid stuff is all I can recall off hand seeing in person. On the internet, everything looks to be digitally manipulated so I usually think 'what is...

  4. Re: How to make a sports viewfinder or wire viewfinder?

    Just looking at your numbers without the exact calculation, it appears you horizontal angle of view is just a little wider than some normal lens, so a viewfinder for a 35mm lens on a 35mm camera...

    People have been putting iDevices in enlargers for years. I'm not sure this is better to us a camera in stead of an enlarger. I may be missing something of what the device does. Either way, where...

    Re: 20х24" enlarger

    Rolleiflex Hy6 I just got will do that. It is called "Focus Trap" and it can be used with a non-autofocus lens or an autofocus lens set on manual. It monitors focus and when the subject comes into...
  9. Re: X-Rite's Patented Sensitometer Electroluminescent Light Panel

    I found both devices easy to make process control strips. I do remove the attached step wedge for each device and measure the steps on my own densitometer. They are not exactly spaced at 0.15logD....

    Re: Suggestions For Wide Angle Lens on 8x10

    210mm is nice as 190 might be too close to your 150mm and 250mm might be too close to your 300mm.

    Re: What size 8x10 lens to match..

    Maybe somewhere around 150mm. No exact answer because the formats are different aspect ratios.

  24. Re: Daydark Street Postcard/Tintype Camera Repair, Safelight Filter Replacement

    Re: F Stops For Portraits Questions

    f11 on a 300mm lens is a bout 27mm
    f2.8 on a 50mm lens is about 17mm

    So, to answer the question; No. You would need to stop the 8x10 lens down to about f16 to get a similar aperture size.
