    Speaking Of Leica Film Bodies ...

    I agree, but I am happier with the very capable and lighter F100. Before someone posts about the F100 door latch, note that I do not use any of my cameras as hammers. I love the way Leica M series cameras feel when advancing the film and firing the lens but the rangefinder drawbacks have kept...

    Correct, to understand the measured value in situ one would need to derive the Thévenin equivalent circuit. https://en.wikipedia.org/wiki/Th%C3%A9venin's_theorem

    Quirks!

    I was told to do that by a coworker amateur photographer decades ago. I found that that worked better for me and I still do it when I work with a changing bag. Part of the reason it works with a changing bag is that nothing in the room can distract me.

    Would you ask your friend to pay for your servicing?

    My long time girl friend was the first non-engineer woman I met that called screwdrivers, flathead and Phillips instead of '+' and '-'. Also when we go off roading and a vehicle gets in a precarious position she pulls out a large pad a paper and sketches a free body diagram and proceeds to...

    Digital back options for Hasselblad 500

    I plan on using the 28mm to 300mm zoom, no vibration control or the 150mm to 600mm zoom with or without the 2X extender and vibration control. Both lenses are F lenses so I will not be able to use the in body vibration control :mad:. I am planning to use one lens or the other with minimum or no...

    What was your last digital photography related purchase?

    So I have to learn to activate the camera early. That will mean that I have to spend more time over target to become one with the camera.

    Would you ask your friend to pay for your servicing?

    I think that you should be compensated in some form for your time and work. You will have to have a conversation with your friends to see how people feel and what can be worked out for mutual satisfaction.

    35mm and MF Camera Chest Harness Suggestions and Recommendations

    Since the weight of the lens can dominate the weight of 35mm or MF bodies the concept of chest harnesses to carry the camera and lens with the lens pointing down and yet allowing the camera to be raised to ones eye in either landscape or portrait position is appealing. One example can be found...

    Adapted Telephoto Lenses for Eclipse Shooting (GX680)

    Unfortunately to get photographs of sunspots, flares and the corona one needs a telescope with the appropriate camera adapter and filters.

    Lens hoods: To each his own foolishness!

    I agree and I have used Skylight 1A filters since the 1960's to slightly warm Kodachrome and Etkachrome film and protection. More recently I have switched to KR 1.5 Skylight filters.

    List of Infrared (NIR) films

    I never prewash the film while it is in storage. I do prewash most films when developing because I have found, following others' advice, that prewashing improves the development consistency and has never, for me, increased fog.

    Ilford Delta 400 pushed to 800 / Not happy, advice?

    I shoot at box speed and when appropriate I adjust the exposure for shadow detail using the Zone System and for any filter corrections. I eschew the automatic ISO reduction.

    Nikon F3: Ending 2023 With A Comeback To Analog Photography.

    I agree. If the camera has problems then have it CLA'd. I was pointing out that a used camera that has an unknown provenance may need to be CLA'd and so I always account for that when buying one unless it comes from KEH because if needed they will provide it.

    The point was that solutions that are basic react with the lipids in the finger skin and turn into soap yielding the "soapy" or slippery feeling. Biochemistry, not Photochemistry.
