  1. Re: Which Camera is Thomas Struth using here - please advice

    I'm not sure how much the Philips cameras cost, I couldn't find any recent sales. An equivalent Chamonix camera would cost around $4,000 new. I don't have a chamonix, but a friend of mine has one of...
  2. Re: Jeff Wall : Please help to identify the camera

    Definitely Linhof. possibly a Master Technika 4x5, though linhof made a lot of variations, so I'm not certain
  3. Re: Which Camera is Thomas Struth using here - please advice

    I'd also say its a Philips Compact 8x10, rather than the explorer. Based on the images I've seen of the explorer (https://www.largeformatphotography.info/phillips.html) It had the corners chamfered...
  4. Re: Which Camera is Thomas Struth using here - please advice

    based on the bellows extension, and that its an 8x10 camera, I'd say its one of the super wide 150s. The two most common of those are the Schneider Super Symmar XL 150 f/5.6 and the Nikkor SW 150...
  5. Re: Does a Photograph's medium change your opinion of it?

    Analog photography and printing is definitely seeing a resurgence, one that I am a part of; I hadn't done any analog photography until around 4 years ago. I think part of the reason for it is...

    Re: 2013 5X7 LED Enlarger Head Test 2

    Have you started your enlarger / timer design yet? I'm working on one myself (8x10 as well) and it would be great to compare notes if you want to.

    How fast can an enlarger shutter be fired?

    Hey,

    I was recently given some pieces from an HK 877 enlarger, including the behind the lens shutter. I don't have a need for the shutter, because I'm using LEDs for my enlarger build, but the...
