Thanks for mentioning this. I've never seen anything about any Fujinon lenses in #2 shutters. It makes me wonder if these were made for a specific market (possible?) -- or simply replaced shutters...

Most importantly, for macro work, you should get a lens designed for high magnification. The Schneider 210mm isn't. And, as mentioned, shorter focal length MACRO lenses can cover LF film if given...

Your statement -- "WS : S = Seiko." -- is too broad, as I pointed out. Only the short W S lenses were sold with Seiko shutters. The longer length W S lenses were sold with Copal shutters -- and...

There doesn't appear to be a hard line. The "middle" focal lengths have shown up with both Seiko and Copal shutters -- probably a gradual shift over time for each focal length. The part that I'm...

Good guess, but the longer focal length W S lenses only came in Copal shutters -- just like the W lenses. The shorter focal length W and W S lenses were the ones that were provided with Seiko...

The NW 180mm lens is a different lens design from the W & W S 180mm lenses (6/6 vs 6/4), that explains the difference in !C (76° vs 80°) between them.

But the question is the difference in the IC...

This is interesting because there was the 180mm W f5.6 and the 180mm W S f5.6. There's lots of literature about the W series, but not about the W S series, but they appeared at the same time. The...

Yet another photographic opportunity.

Urine normally has very low levels of bacteria, and a PH close to 7. It's not as bad as many assume.

Urine is usually very close to PH 7 -- unless this mouse has a kidney disease. Why do you assume it is acidic? Coincidentally, I tested mine last week and it was 6.8. You probably don't have to...

I'd worry less about the brand name, and find a lens that meets your needs -- that will be hard enough to figure out. Even then you'll have choices to make. Fuji alone made almost a dozen 150mm...

Most of my metal frames are 5/16" -- just over 1/4". I don't consider either of those "thin". Someone probably makes a 1/8" frame -- maybe even thinner. That's what I'd call thin.

A Seal 500T would do it, but they don't grow on trees. To avoid the inevitable seams, is a single 34" print out of the question?

Fujinon made lots of 250mm and 300mm lenses -- old style (barrel) or new (Copal) -- some inexpensive:

So the only "ventilation" into the darkroom is when the "window" air conditioner is ON? If so, that needs some explanation. That's not going to get air in -- or fumes out.

You need to tell us what this means. Is the "ventilation" filtered or not? That will make a big difference. How much "ventilation" / air flow is there. We aren't there. What, if anything, can...

Even though some enlarging lenses are multi-coated, it's more of a sales gimmick than anything else -- but sometimes enlarging lenses are used outside the darkroom, so why not?

I don't see any transposition.

Does it look like this monster?
...

I appreciate the sentiment -- what my soul wants to create in a photograph is what I saw -- a marvelous panoramic sunset. But getting it to be a 3x8-foot print on my wall means cropping and...

Welcome to the FORUM.

If you plan on a lot of close-up and macro photography as a professional, you might find digital cameras to be more useful than large format.

Not even for blackening the blacks? If it weren't for that, I'd just use Sistan.

Thanks for mentioning this. Gold toners appear to have a certain reputation, but not all are cold or bluiish -- as I pointed out in Post #3.

Do you currently have any lenses?

The 63mm f2.8N had a list price that was 65% higher than the 50mm f2.8N.

Since all the Fujinon EX lenses are 6/6 design, I assume that is the case. I know the 50mm f2.8 is.

One point that is often not considered is the position of the camera before any tilting is applied. In many cases, instead of placing the camera in a perfectly flat/level position on the tripod, if...

You can always use RC paper to test your archival process -- even if RC paper is not archival enough for your standards -- and then move to a fiber-based paper once you've settle on a method.

Maybe it varies with different papers, but selenium toner on the Ilford RC paper that I use creates no change in the tone (if dilute) or a change toward purple -- not warm. Gold toners can create a...

I have no complaints with mine, but I'll admit that the 53mm x 0.75mm thread is not common -- but it has a very convenient front thread of 55mm to make up for that. I found mine, used, at a great...

Yes, you may have used too much tilt -- or not enough. I would think that f22 would be good enough. The best approach is not to use your eyeballs, but to use a magnifier -- called a loupe. These...

All my older black and chrome Componons have 14/15 blades, and the new ones have five -- as pictured. I've never run a comparison, but my old ones (all under 50mm) are great.

The short answer is that both Linear and Circular Polarizers do the same thing. The actual polarization effects such as reducing reflections on glass surfaces, increasing color saturation in foliage,...

or used a grain texture screen in the enlarger -- extensively discussed in a similar, recent thread.

Another option is to use use smaller format, such as the half-frame Pen F.

Royal-X Pan -- not to be confused with Kodak Royal Pan.

ASA 1250. Comparable to Kodak 2475 Recording film in grain.

At the Oscars last night, Christopher Nolan started his acceptance of the Best Director Award with a tip for other Directors -- especially budding Directors -- "Consider celluloid".

He made...

Nikon, Rodenstock, Schneider, and Dyotar (Fuji) all sold 180mm enlarging lenses intended for 5x7" so they all thought the focal length was adequate.

'nough said.
