I'm participating in a group exhibit by the Signature Artist Cooperative has a group exhibit at the Arts Council of Greater Kalamazoo, 359 S. Kalamazoo Mall, Suite 203 , Kalamazoo, MI 49007. August 28 - September 25, 2015. The opening reception is Friday, September 11, 2015 from 5 - 8 PM. If you are in Kalamazoo stop on by!
I found several rolls of long expired Pro Max 100 film in my freezer a few days ago. These rolls are very old and when I last used film from this batch it showed severe signs of aging and spoilage. So I figured I'd run some tests to determine the best development time and strategy. If possible, I also wanted to push it a couple of stops to make it more suited for hand held work.
This image is Pro Max 100 pushed to ISO 400, stand processed in HC110, 1:75, 20C, for 90 minutes. The original film is soft, low contrast, and low grain. I boosted contrast in Photoshop and blended in a high pass layer to boost the grain a bit. (I like grain.) I think I have a passable exposure and development strategy for this film - now to burn it up and get rid of it!
One sign of the spoilage in this film is notable staining once developed. It appears in both stand processed and standard processed rolls - basically the stains are faint brown bands that are distinct in color from the developed emulsion and can cover half a frame to a couple frames on the film. So - not a film to be used with critical work, for sure. On the bright side - the canisters this film is packed in are reusable so once it's used up that's more canisters for bulk loading plus more plastic cans.
Green Bottle Fly, a common fly of the genus Lucilia:
I usually learn something new with each of these super-macro sessions. The lesson in this case was that specimens do not last forever in the freezer! I have collected a green bottle fly some months ago and finally got around to preparing it for photographing a few days ago. When I got it in the camera's sights I found a dent in one of the eyes plus the cells in the compound eyes looked very irregular. Looking very closely I realized that some fo the cells int he eye had collapsed - they no longer bulged slightly outward, but rather some cells now sank back into the eye. Some cells had gone from convex to concave, and so reflected light differently and created an irregular aspect to the celll pattern of the eye. Snatching a fresh bottle fly off a leaf and photographing it a few hours after collection revealed a very regular pattern to the eyes.
So - at lease some insects must be fresh to get good results when photographed, or perhaps I need to find an alternative method of storing them.
This photo was made from 154 stacked images at approximately 5x lifesized.
I'd tentatively identify this as a Treehopper, Membracis, ssp.
Eighty four stacked exposures (two separate stacks combined) taken at about 4x lifesized. Pentax K3 with reverse mounted K 24mm f3.5. No extension other than the adapter rings used to reverse mount the lens.
