If I may ask, where did you get this done? I have an old Dagor in need of this service.

Very comprehensive reports on the lamps' spectra. Impressive.

This may have been asked (and possibly answered ...) before: Is there information on the spectral sensitivity of the individual...

A very common problem, I understand.

(Cough)

My experience with 10 year old film (that's still pretty young in my book) is to expose and develop normally. You might lose a bit of shadow speed and so Rodinal would be the worst choice of the...

Ditto Mr. Racer. Cheap enlargers are crap when it comes to producing even light. Hang a bulb from the ceiling - good enough for Edward Weston.

If you want to go full luxe look for a nuArc...

A good rule of thumb for doubling a linear dimension (10" -> 20") is that the weight will increase by a factor of 8. As will the price.

If it is an 11x14 with a 16x20 back then the increase may...

I try for a wash temperature of ~75F. The warmer the water the faster the wash, within limits. Warm wash water has been said/rumored to increase grain. Very warm water may loosen or flush away the...

The old peel-apart style would fade to a very pale brown if they weren't coated. I don't know if these films are still made.

Well, the usual photographic fading is 'fade to black' - easily done by eliminating the fixing step.

Anthotypes - made using plant pigments - will fade away with exposure to light. Heck, fading...

It is a specialist sub-genre specializing in atmospheric views of trees and coastlines. Popular along the northern Pacific coast. Often referred to as the "f-who-gives-a-damn-in-this-fog" school of...

Expect very slow developing times - 10 minutes or so. I tried this in my youth when I ran out of paper developer and gave it up as a bad idea.

There are "universal" developers, with these you are...

Very, very, very, good - can you tell that I like it?

If it were me I would Dremel the screw heads down to nothing and then pry the wood apart. That should leave a stub of a screw remaining and that I could unscrew with visegrips.

In a Vonnegut book an Indiana senator was feted for defining pornography - any image with pubic hair.

Jon Oman posted the really squiggly thing.

OK, Jon - what is it?

Rodenstock made many of the nuArc branded lenses.

If the purchase is under $800 there are no customs fees. Even over, there are often no fees.

You like "Crazy complicated"? - why you are just the man for f-stop printing with all of its accoutrements.

Well, maybe not, it does have the danger of simplifying things for some people. They...

Windex is entirely appropriate. Windex won't attack glass or plastic. Lots of rubbing and scrubbing will scratch things up - so a cleaner that really works and minimizes cleaning abrasion is the...

Fixer has a high markup. The cheapest is to buy 50lb/25kg bags of S. Thiosulfate crystals. Cost from China is ~$0.25/kg for small orders. $0.10/kg if you buy by the tonne. Shipping extra, suggest...

How about a Speed/Crown graphic. It appears to tick all your boxes.

I would advise sticking with RC until you can get prints you like. Note that RC paper is available in warm-tone.

When starting out most of the prints you make will go in the trash. Not using...

My experience with digital proofs is that it is a PITA compared to the traditional darkroom method.

It doesn't take much of a darkroom to make proof sheets: a few trays, a red led Christmas light...

There is also the financial side: 250 sheets @ $4/sheet = $1,000. Worth salvaging, if you can.

Try a few sheets and see what happens. Only you can be the judge. 15 minutes of your time and you will have the definitive answer.

Now, get thee an enlarger and a wet darkroom.

With a high-end scanner and a high-end printer it is possible get good-to-passable results. But the meanest of darkroom gear, taking less time and...

I'm going to be in the back yard, Cleveland is right in the path. Problem is, the chance of overcast skies is ~50%, Cleveland is no sunshine capitol.

If I were to take pictures it would be of...

The Ohio population of 17yr cicadas came out a few years ago. It was underwhelming, nothing like the past emergences.

Insects in general have vanished. When I was young (50's & early 60's) if...

I had a Star-D Tiltall that served for some years. Then the aluminum castings making up the tilt-head cracked in several places and it was retired.

I have several Gitzos, a Benbo and a Reis (from...

I was 8 and my camera was an "Empire Baby." I read A Boy's First Book of Photography, or something of that ilk, taken out from the children's section of the library. I bought a Tri-Chem pack at the...

I find isopropanol (isopropyl alcohol) helps with sheeting the water off the film.

I make up a stock solution of 13ml PhotoFlo 600 (40ml of PhotoFlo 200) in 1 liter of isopropanol. This gets...

If the meter is the problem in cold weather then fresh batteries may fix things - just like an old car battery can't crank the engine when it is cold. Ditto cold lubricants in the camera can stiffen...

Interesting result. Normally light output increases with lamp temperature - viz the time it takes a fluorescent or cfl lamp to come up to full light output as it warms up.

Having had an Aristo...

Paper exhibits no intrinsic intermittency effects -

Compensating for lamp warm-up time (I'm sure there is...

Well, an f-stop timer will do all the calculations for you.

Base time can be determined with an f-stop enlarging meter - some are separate and some are integrated with the timer.

Enlarging meters work the same with RC or FB - there is no difference.

Well.... I have to differ.

Both emulsions have the same contrast. Each emulsion contributes to half of the print's density. By controlling the relative exposure of the blue and green sensitive...

Border staining can be due to active developer in the print emulsion reacting with the dissolved silver in the fixing bath.

If this is indeed the cause of the staining then using acid stop bath...

A very impressive body of work.

I'm as much of a sharpness geek as anyone. I make 20x24's from 35mm negatives and examine the corners of the prints with a 10x jeweler's loupe. APO lenses for 4x5 and the enlarger. Even as I argue...
