If the bottle has not decomposed, the developer should be fine. YMMV regarding the fixer, as by their MSDS all Lauder fixers contain acetic acid, which makes them somewhat unstable - all acidic...

Depending on the storage conditions and grade of depletion, I have experienced one to four weeks without visible degradation, with the preceding Tetenal C-41 "Press Kit". The current Colourtec is a...

Initially, pushed to the cheap fringe (or made so oversize that they did not compare favourably to 60mm) by being not big enough to be beautiful. When the US shoppers discovered, via GI Leica imports...

That would be Topcon. Mamiya also had one Exakta mount camera, the Mamiya Prismat, their first SLR. Which only had a Exakta mount in its Mamiya branded version - other variants were (more...

That is entirely a matter of budget - there are affordable wax (or thermoplastics) jet deposit printers that create soft models for purely visual prototyping. The mainstream of current laser exposure...

Nope, that was designed by Zoomar (of Rochester) and made by Kilfitt (of Munich). Voigtländer licensed the right to market it first, re-branded as Voigtländer Zoomar, but they were made by Kilfitt,...

YMMV as to local distribution - that pretty much depends on the ups and downs of the local importer and the popularity he can generate through advertisements and promotion. On the large scale, their...

Zeiss Jena kept separate from Pentacon until 1985 (when Pentacon was merged to Zeiss Jena, not vice versa), and did not suffer the same degradation to the bottom end of the Western photography market...

The UK will have been different, as they had steep import taxes directed against anything outside the Commonwealth and were only reachable by ship, so that Japanese and European/German makers had...

Voigtländer never made a Exakta mount lens. They doubtlessly shot themselves in the foot, and deservedly were the first to fail (and be gobbled up by Zeiss). For some reason they seem to have...

Was it so in the US? It certainly was not in Europe. Japanese brands did not even appear on the European market until the early sixties - the rapid swing from a German dominated to a Japanese...

Not at all - the Exakta had its peak in the fifties and carried on into the late sixties. The company, Ihagee, was Dutch-founded and -owned so that they, as a foreign company, escaped the immediate...

Well, the absorption into Pentacon was relatively late, the real issue was that the GDR believed in industrial scale production - which is a matter of numbers, and hence most feasible for small (and...

It world not be the first product with a flaw - nor the first invention with a inherent flaw. Besides, people have made (sometimes odd) compromises - is the lens unusually (for the period) wide,...

Tenths of a millimetre can already be critical - 4mm is very significant. If you cannot shift the plates forward in the holder (perhaps not, if you need some depth for a drip receptacle), you will...

The last I saw of Ultrablitz was as part of (Frankfurt based electronics, not Nuremberg camera) Braun. They continued to use the name Braun Ultrablitz for part of their flashes into the SCA age.

I suspect that these flash heads might actually have been made by Osram (who held the flash tube patent at the time) - they are typically unbranded and I've run across them with quite a variety of...

No - that is the other way around. Pre WWI nickel platings can be glossy, but they were deposited dull and had to be polished (and to be thick enough that the polishing did not wear them through),...

Zoll/Inch/Pouce all are derived from the Roman uncia (1/12 foot), roughly a thumbs width - but with plenty of variations that crept in over the course of time (in this case, slightly longer than the...

These questionnaires are randomly sprung on you if you don't un-check some option during registration. They probably end up at some third party consultant and get mangled into customer satisfaction...

Heico Perma Wash seems to be a mixture of soap and ammonium sulfite (and perhaps some stabilizers). You could mix something similar on your own. But there is not really any reason to believe it to be...

Yep - but that, along with the Siemens generators needed for large scale plating, came a few years too late to affect a French 1867 lens in its production. That lens was either plated later on in...

You mean solid German Silver? It looks a little too blue for that (the alloys from that period are yellowish), but that might of course be a issue of the picture. Solid German Silver would be more in...

In 1867 it would have been quite exclusive - probably not out of reach for a maker of optical/scientific instruments, but not yet a everyday technology. If the lens were a decade younger, it might...

Perhaps. Or as part of the corrosion proof "tropical" finish of these years. Or as a modernization effort in later years, maybe to add some more glamour, or to hide the fact that some restored part...

Yep. That is, I use the 64bit version. The GUI is rather Windows XP/PS7 age, but the software works well.

Yep, the non-Sinar way of doing things was that meter probe holder ("Meßkassette") - these sometimes show up on ebay. Rebuilding the TTL probe wand so that it works as a behind-the-glass meter...

Nothing large format, hence off topic. That is a fifties to sixties Exakta (35mm SLR) tele from a venerable West German maker. Not bad, but, unless collectors grade, no treasure either. Going rate in...

I've quit using MS Office for good - between nauseating perpetual interface changes and Openoffice and Google Docs growing good enough to replace it, there was no point in keeping it even for legacy...

That is only an option if you are a hobbyist that does not publish. There is barely a niche left where you can work with photography without at least samples of your best stuff leaking onto the...

Or a side product of standardisation - most makers offered some lenses in both barrel and shutter mount, and used barrels prefabricated in standard shutter sizes for that purpose. Economy dictates...

Well, work with exposure times notably below 1/50s might benefit from DC powering. But contact printing? You would not even see a difference if you exposed the contacts with flashes in ten-second...

True. Except for the odd few exceptions - which might not even exist in the US. German films are usually produced by some subsidiary or contractor of a TV station (some big enough that a rental...

Overpriced, but not quite as interstellar as it might sound - the five digit "items" he has around are extensive kits kits of still desirable 35mm cine primes. He is obviously after the rich, but...

That may be true for the largest models. The 4x5" and smaller colour heads made do without asbestos. All Durst heads I have owned were all-metal, with no heat resistant non-metal boards anywhere in...

Sure your problem is not in the printing or scanning? Or some handling error? It certainly is no matter of film, speed, developer or development times. Tri-X at nominal speed developed to spec sheet...

Right you are - I did not see the second line of images with the Symmar. That is a Aristophot. The same components and stand, with a field lens and adapter tube instead of that Symmar, also went on...

That is a microscope attachment camera - Linhof provided the Leitz microscope division with medium and large format recording cameras at least into the eighties.

Wood monorails have been attempted frequently, but all I've ever seen were very wobbly - try to change the design to a base plate or dual rail construction. Or make the U frames solid metal.

The protective sheet tab should protrude by about half an inch, and the tips of the white tabs should be visible underneath it. Most people try to be too complex - the pack is simply placed in the...
