Cold mounting is now routine for color prints on smooth substrates like aluminum. As I already noted on an ancient post somewhere back on this thread, I did used to make custom laminates of aluminum...

Just call Formulary for advice. I happen to use TF4 in combination with weak acetic acid stop bath. No problem. There's enough alkaline reserve to handle a bit of acid carryover. But it's mixed per...

What was that all about ? Somebody had to think about it for two and a half years? First time I've ever heard the word, chutzpah. Some kind of insult, I guess. In any event, museum display...

Hmmm ... There are still some Raiders fans in this area. They tend to drink solvents outlawed anywhere except at the racing pumps at the Bonneville Salt Flats.

Another problem will be if the glue outgasses between the elements when curing. You'll want to do a preliminary test on something else analogous first. Regarding solvents, ordinary hardware or paint...

I prefer to use an ordinary 125 Fujinon W (or NW) to something like a 120 Super Angulon for general use on 4x5, not only because it's a much lighter lens, but because there's way less falloff and...

Just be aware that ordinary pool supply or hardware store muriatic acid is still plenty strong enough (around 18% hydrochloric solution) to destroy your lungs if you spill it in an unventilated...

Retrofocus would apply mainly to SLR's. But if the lens design is similar, apples to apples, the format size won't make much difference relative to angle of view unless image circle movements are in...

It gets even worse. When I was researching heavy-metal dye mordants, I was surprised at all the nitpicky paperwork potentially involved, and learned that it was because idiots had begun smoking...

Lenses are easy. What about multiple sheets of big enlarger glass? Q-tip is of no value there.

I didn't know about the Woodbury types, but that is one of the processes I discussed with them about reviving in some more modernized fashion, specifically by laser-etching epoxy blocks. But there...

35mm wide angle lenses do have equivalent falloff, Alan. I personally hate that Natl Geographicky look. Falloff is more noticeable with chrome film simply because chrome film has more native contrast...

A densitometer with actual film works better for checking, unless one has a film plane probe meter that will get clear to the corners. But what I do first, just to detect for falloff, is overdevelop...

That's why I don't use a cloth! (lenses and filters being the exception)

Hmmm. During my wife's previously biotech career, she had access to lots of nearly pure methyl alcohol. It was an incredible cleaner, which not even any kind of 90% alcohol solution would be, but way...

He's been seriously physically handicapped for quite awhile now, and that factors into his ability to still paint or not. But I tend to get bored with just one self-portrait after another. Many of...

Well, I guess we're all still all looking for that silver bullet. I made out pretty good yesterday. Just one tiny speck on all of my 8x10 contact separations, which will easily spot out. Got quite a...

I go through this hell multiple times a day. The worst is when making multiple registered sheet film color separations and masks involving meticulous cleaning of both glass and film over and over...

Some of those get selected for huge scale reproduction by various novel means, done in this area. I was marginally or peripherally involved in a couple of those projects in terms of how-to...

You need to get all the dust off in the same cleaning step. The harder you try afterwards, the more you'll just get back on. A few inevitable bits can be blown off; but basically, you don't want to...

I miss the hills. While everyone was going crazy looking for Snow Park spots up the road, I'd be exploring the lower Kings with nobody in sight for miles. At the moment, I'm too miserable with...

If you want to pay for it, Edmund Scientific can source you the same kinds of products lens manufacturers use. It's a paint-on peel-away product, obviously not for routine glass use, but for that get...

Does it come with free Mickey Mouse ears?

You need to be more specific about exactly which 300's you're comparing. Just because something has a smaller shutter does not necessarily mean it has less coverage.

Color shift in the corners is inevitable with a film of that high a contrast. Whether that looks attractive or doesn't all depends. It might be better to just let the falloff go toward black if a CF...

It's no dog. But it certainly wasn't engineered for full aperture usage. Nor were any of these. I'm not a tele user myself, but do know people who have had exceptional outdoor photography careers...

Bernice - those old chrome Tele Xenars weren't fully color corrected, so not the best idea if someone has color film shooting in mind as well as b&w. My brother used em.

So it was not a recording of an actual event, but by an ethnographer later. I spent a lot of time searching for where the Ghost Dance transpired in my own neighborhood in the 1870's, and tentatively...

The places I've seen RV's broken down all over the West, oh my, my, my ... There's nothing quite like being towed down a desert highway and spending most of your vacation in a Motel Six in miserable...

Read the "fine print" on that particular Schneider lens, Bob. I was following official specifications!!! The rest was completely tested, no guesswork. So I can most certainly tell people what I know...

Well, as a potentially extreme condition, I'd point out just how fast salt water or ocean spray can corrode materials and electrical contacts in a manner ordinary water cannot.
Anyone who owns a...

I knew you'd contradict that, Bob. But not only did I do a lot of expensive commercial shoots that way, but have made extremely detailed 30X40 inch Cibachrome enlargements of such shots - a far...

You don't need 105 mm filters. Circular 82mm contrast filters between the CF and the lens work just fine.

Any basic HVAC repairman knows not to leave batteries in a piece of test equipment over time. Just a year or two ago a multi-billion dollar satellite under construction was burned to pieces, along...

Alan, that big 90 sits close in, unlike a heavy long lens at full bellows extension, so is relatively easy to stabilize despite the weight. If it were something like a big 300/f 5.6 plastmat in big...

Asymmetrical controls are wonderful in production tabletop studio applications, including cuisine photography. I once did a bit of tabletop, and learned how these things work, but promptly forgot it...

All kinds of studio monorail cameras had it once certain Sinar patents expired. Having shot a variety of Sinar cameras for decades, I don't pay any attention to that feature.

It's instructive to watch reruns of the Beverly Hillbillies. My style. Helps to bring your own goats along.

Varta is one of the better brands. But some of these brands have a new numbering system. Somewhere in the fine print PX28 will be mentioned.

Sal, please don't take this personally and start another useless argument. Multiply any of your anecdotal personal experience about this topic and multiply it by about 100,000 times. We were not only...
