  1. <p>There are rules of thumb too that vary with the meter. Generally if there's lots of light you want to close up a little bit, if there's very little light most of the time you'll be more trusting of your meter. You'll correct the underexposure by increasing development. -If you find an old Pop Photo magazine from 1960-1998 there will probably be some great info on this subject. A large portion of there articles seemed to be about this alone.<br>

    <br /> The other option is to use a digital SLR as a meter and take the shot with it first. If the image looks good there then it will probably look good on film. There's two issues there however. The main one is that digital cameras are arbitrary with the concept of ISO. What's 100 on one could be 50 on film or 400 on another. The other issue is that the dynamic range is very high. So getting something to look good on a DSLR is a lot easier than on a roll of Ortho.</p>

    <p>I hope that helps, although it may not make things easier.</p>

  2. <p>Indexing is when you set up your film and camera/meter to a chemistry, usually at a certain speed. I used my L-398 with the bubble on when I was indexing my film (Arista ) and I have a speed and development routine that works well for me.</p>

    <p>In the past you would index your film to labs as well. As one mini lab might be + a stop while the grocery store was slow. -When you have 3 color films and 5 black and whites to manage it was a head ache! It was the main reason I started to develop my own stuff. </p>

  3. <p>I recently picked up an M2 for about 380 US. The chrome could use some polish, and, side from replacing the leatherette it was a great deal. I've tried 99% alcohol and an eraser. Is there anything else that could shine up the chrome on this bargain? <br>

    Thanks in advance<br>

  4. <p>I know that for medical imaging in Ontario (particularly X-Rays) they have an on site dark room at the hospital/dentist. <br>

    I think the title is "medical imaging technician". This may not sound great but at least its proof that its out there.</p>

  5. <p>Don't rule out lighting or temperature. In bad light, AF can take longer to line up and cold can cause electronics to lag depending on the camera. If the entire roll is shot in one location or time period, it could be an overlap to location or weather.</p>
  6. <p>I have a few questions about the CL. <br>

    I know that you can put a M3 lever on a M4-p with the right tools and parts, is it also possible to do that on a CL?<br>

    I know there were a number of improvements made to the CL over its production. Should I go for a late body to get the most improvements? I would prefer a Leica body.<br>

    Has anyone had their CL recovered in a different texture from a company like camera leather?</p>

  7. <p>Thanks Greg, are the 50mm lines view able with the 1.4x magnifier?<br>

    Also I've looked at that link, but I've also read on other sites that all Leica base lengths (not effective base lengths) are the same, thus the question.</p>

    <p> </p>

  8. <p>I'm looking at buying a M4-P and I've read some mixed information.<br>

    Does the M4-P finder show 28mm frame lines or does it only go to 35mm?<br>

    Does the M4-P have the same base length as a M3? I'm going to put a magnifier on it and i would like to get as close to (or better than) M3 EBL as possible.<br>

    On the models with a brass top are the gears steel or brass?<br>

    Lastly would it make sense to go with a 1.25X magnifier for use with a 50mm or could I look at a 1.4x? </p>
