Pinholes have virtually infinite depth of field due to the physics of light diffusion. Pinholes don't focus light like lenses do, and therefore their images appear softer than images captured through...

X-ray film base is blue because it is a transparency, looked at on an illuminated light box along with hundreds more over the course of a long day. The blue tint enhances contrast and soothes eye...

Some Foma films had a blue base until recently; I never had issues re: contrast using VC papers with them or with double-sided x-ray film.

Latitude film is designed to have the lesser contrast of the two films Alan9940 mentioned. In x-ray terminology, "ortho" means green-sensitive, as opposed to "regular" which is blue-sensitive. The...

Kodak GBX2 filters were used in x-ray darkrooms with ortho (green sensitive) film. "Ortho" was the term applied to green-flashing phosphor screens and green-sensitive film. The blue stuff was termed...

Luka, do you mean Silicic Acid?

FWIW I've found "thin" pyrocat negs print remarkable well on silver-gelatin.

My Navy fleet hospital (500 beds in a tent with expandable ISO containers) was initially supplied with green-flashing intensifying screens and blue sensitive film. The two are entirely incompatible,...

It's not unusual for a Christian church to display items from Jewish tradition. On the retable in my Lutheran church the candle holders are shaped to form the Hebrew words chesed and shalom.

I believe the 100 and 400 speed refers to system speed: The imaging system consisting of the film and the proper intensifying screens that fluoresce under x-rays to expose the film. Place the wrong...

I use picture frame glass on the bottom of a tray. I develop for 6 or 7 minutes sloshing the tray, and turn the negative over maybe 4 or 6 times. I have no trouble manipulating the film (There's just...

This place offers the 14x36 straight film in blue and green sensitive, 25 sheet boxes for $60US. I've seen radiographs made with the trifold and the images were certainly of diagnostic quality,...

I tray process my 8x10 xray film with a glass plate covering the ribbed bottom of the trays. Works fine. No scratches. I don't strip the film, either. Plenty sharp for me.

I shoot Fuji HR-S (green latitude) @ 100 ISO, but I don't strip either side. I use a rotary paper cutter with mat board strips taped to the cutter's table for my guides to cut 8x10 down to 4x5....

I like the abstract quality of that lovely image, JoeV. A dulcimer doesn't lend itself to the type of shadings stradibarrius photographed so well with his fiddles-- Flat vs rounded. But I like the...

Thanks, stradibarrius. She's got a complex voice for a dulcimer, but retains the frailty that's the charm of the instrument. The redwood, I think, darkens its tone. I wish I still lived close enough...

First time using BT2B developer.

Thanks, Vaughn and Preston. I did print it darker, and it did have a more ominous look.

I like the texture and colors the low-incident sun gives your picture, Preston.

The Kodak Wratten 1A will fog ortho x-ray film. You need a GBX filter.
