I am definitely not a pro, and just perform basic fixes (broken doors, lens cleaning, stuck diaphragms, minor shutter repairs, general electrical repairs as this one here). My utmost priority is on functionality, so the goal is to have the equipment up and working with as durable a fix as I can...

I usually develop in D-76 (1+1), too, and the developing times are usually over 8 minutes for most combinations of Film/ASA rating I can think of. From this table, I use a slightly modified Steve Anchell agitation method (this really is my dad's agitation method, just stuck with it :tongue: ): I...

I do agree with this analysis as I fail to spot a density difference in the foreground tarmac. Is it possible the enlarger is still mounting the 35mm (narrower) condenser (if a condenser enlarger)?

Talking about 135 format: I am fairly positive that RPX100/400 and Kentmere 100/400 aren't exactly the same. I mean, the emulsion looks remarkably similar and, personally, I wouldn't be able to tell 'em apart, if subject to test. I personally also like them both a lot and had shot some of my...

Now I can start dreaming my next Pentax SLR :)

For Zinc-Air: https://en.wikipedia.org/wiki/Zinc%E2%80%93air_battery#Discharge_properties https://www.microbattery.com/pub/media/tech-specs/pdfs/A675MF.pdf (the plot is for hearing aids: they drain way more current than an exposure meter and, indeed, measuring the voltage at the cell's poles...

The forward voltage drop of a small signal shottky like the BAT85 is around 0.21V at the very low current drain of an exposure metre, and a silver oxide cell yields 1.55V, thus the resulting voltage of the concoction is 1.34V. I compared the readings with that of my minolta spotmeter F and they...

Because pecunia non olet: more film being burnt means more shutters firing and, consequently, more cameras failing and, hence, more replacements. True if it meant new product development, but we're talking about equipment sharing a lot of electromechanical components with the digital reflex...

you can quite easily adapt your mercury meter to accept silver oxide batteries and then drop their voltage with a shottky BAT85 diode for each cell if you like the meter, or just buy a bunch of zinc-air hearing aid cells (675 format for the usual px625 mercury cell): they are short lived but...

This is just so true. I am having an hard time accepting that Canon and Nikon phased out their line of film cameras when it was plainly clear that film was experiencing a definite comeback. It looks almost like a challenge: we have photosensitive materials manufacturers having an hard time...

I guess that basically all the criticisms push processing magnetize ultimately boil down to the misconception inexperienced photographers have about the ASA dial on film cameras, ie: that it magically makes their film behave like the digital sensor with increased gain LNAs (albeit "low noise...

This Toyokaflex I never heard of, but it indeed looks like a most interesting camera. I have both a Seagull 4 f3.5 and a bunch of Lubitels I got from poland (lubitel 2 and 166u), some quite old. The Lubitel 2 is made from a very nice material but finding 27mm push on filters can be a real pain...

thx! Excellent Italian :P

Reviving a bit of an old thread but was wondering about contact sheets myself a few days ago. I definitely don't enjoy making them, it's what I found to be the most tedious darkroom work, but for me they are next to necessary, and a good activity when I am too tired to delve into some more...
