So, here's a weird thing. These are two adjacent images from the same roll of film - the old, old roll of Kodak 124 film that I shot in the No. 3 Brownie. The picture with the tape residue was the very first image on the roll, and the picture looking straight on at the signs was the next. They were shot within about a minute of each other. The only thing I did differently was set the Brownie on the ground for the first picture and took either an extended exposure or just flicked the shutter lever a few times (I can't remember which), whereas with the other photo, I held the camera in front of me and took an instant exposure.
I scanned these in as color negatives, since my scanner seems to pick up more detail on fogged film that way. They were both scanned in as a negative, which means that, theoretically, the image produced by the scanner should be a positive image.
So, why do I wind up with one positive and one negative image from two adjacent images on the same roll of film? Hell if I know, but that's what happened. Actually looking at the film, the image on top is a negative - like it should be. But the second image actually somehow reversed itself so, that on the actual film, it's a low contrast positive image. WTF?!

IShot at ISO 3, then developed in paRodinal 1+25 for 5 minutes.
This is so much brighter than the Caltar or the Apo-Artar images (both f/11) for a very simple reason - this lens is mounted with a Packard shutter, so I have to manually sync the flash - my guess is that I sync at 1/2 second! The ambient light level at 1/25th was f/2 according to the flash meter.
Negative Space was created to place two images in a single composition occupying each others negative space much like Rubin’s Vase.
The P.O.I of this photo are the two oyster catchers. The rest of the image is just white cloud. This brings attention to the oyster catchers as there is nothing else interesting to look at in the image.

Filter Comparison 3: Orange Filter, Ilford FP4 Plus B&W Negative Film, Zuiko 24mm F3.5 Shift Lens @ F11, 1/30 sec, Olympus OM-4T
This comparison sequence of photos was taken during late afternoon, so the light was rather warm. The biggest change in darkening of the sky is going from no filter to the yellow filter. The orange and red filters have slightly darker skies than the yellow filter, but the change is not much.
Also see my midday filter comparison sequence, where the relative effect of Orange and Red filters on the sky is much stronger.
Calotype whole plate negative Clearprint 1000H paper. Exposed 6 min on a bright day, midday at f/9.
Paper sized in 0.5% potato starch for 5 min in a warm bath, air dried.
Iodised (Greens iodiser no1, Iodide only) with 0.5% potato starch for 5 min. Air dried
Sensitised for 3 min by floating on a slab of glass on replenished solution (Green sensitizer no3 ) with reduced acitic acid for shorter exposure times. Exposed immediately in room temp through a window.
Developed in 0.8% gallic acid by floating, added a few drops Silver Nitrate 8% after 5 min developement, total 13 min floating
Washed 2 x 5 min
Hypo 2 x 10 min
Washing ca 1 hour
This test should provide higher contrast compared to test 1. The loss of speed may be due to separate sizing procedure, change in iodising solution, or less sensitizer absorbed (least probable). Shadows seem to be clear except for stains on the right side.
I've just found the negative to these photos www.flickr.com/photos/mildlydiverting/9028033/in/set-7215... in an old photographic paper box in my parents' cupboard. The strip is folded, and one frame is badly torn.
I'd really like to scan these to get better quality images, but written along the side of the negative is a fatal phrase - NITRATE FILM
Does anyone know anything about how to handle this stuff safely? What are my options?
More photos from the pinhole camera I made in 5th grade. On the right is the negative, on the left the positive. Both on photographic paper. You know, I actually can't remember how I exposed the negative onto the other piece of paper to reverse it. This is taken behind my dad's photo lab-- I must have used one of the many enlargers that he had.
