There are slight differences in curve structure and grain due to different developers and how much they are diluted, agitation, time, etc. But all ordinary developers work well with all these films,...

Find me a torpedo level that is actually level. Yes, I have a couple of them, truly precision machined. But you can't walk into Cheapo Depot and find something like that. No big deal. Film almost...

Glad you got the shot, cause not many will be standing for much longer. You still sometimes see old schools like that out in Mormon sagebrush too.

The bullseye levels I see on camera store and studio shop leveling devices are a joke. Do y'all know how expensive a true machinist grade one is, or how difficult it is to attach truly flat unless...

Nice video. Don't see how it has much relation to far bulkier view camera applications, unless maybe ultralight 4x5. Even that flick setup for 35mm panos, plus bowl adapter and quick releases, would...

I use several options, often depending on what's leftover from lab usage. But for shooting in the field, my current favorite 8x10 product is unquestionably TMY400. Very long scale that will resolve...

From a practical standpoint, the lens manufacturers already plotted this for us in terms of their given focal length selections in any given series. They mainly made what was in demand, and the...

One warning about going too light. It makes the whole setup rather top heavy, and more susceptible to wind tipover, and to having difficulty with stabiiity on mossy spongey ground. There's simply no...

Maybe I'm just really jealous of his custom made camera.

'Goodbye Cibachrome"... more like, "goodbye common sense". Bare handed, no respirator, fooling around with sulfuric acid bleach.

Magnolia is an Alt process lab which did a lot of special experimentation, especially involving scanning and laser etching, which has nothing in common with this particular thread. In recent years,...

How low a ceiling do you actually have? The Durst 138 enlarger chassis is highly desirable, even if it takes awhile to assemble all the needed extra accessories. If you're not doing color printing,...

90 + 150 = 240. Divide that in two or average it, and you get 120 as the midpoint. Like I already noted, there are a number of lenses available in the 120-125 range to choose from. With 115, just a...

It all depends. There are many brands of carbon fiber tripods and they're all over the map in terms of price and quality of build. For large format work you want something solid. For routine usage I...

Yes, E6 and C41 are film processes. RA4 is a print process, and can be achieved either via optical enlargement or scanning and laser printers. One generally has to do a little more in depth...

Ditto. My recent enlarger bellows from Custom Bellows UK certainly resembles the same bellows material on my own Phillips 8x10.

In real world usage, and in terms of commonly available lenses, a 120 to 125 focal length would be the most obvious halfway house between 90 and 150. I can't think of any 110 except the very...

Huh? The Darkroom still does C41 and E6 in the LA area, clear up to 8x10 film size, that is, in San Clemente nearby, and offers printing too. There are labs still going here in Norcal too.

The unopened box of Ciba paper left in my freezer has probably developed too much crossover for reliable results; but someone wants it anyway for fun experimenting nonetheless. My P3 chemistry might...

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...
