Semi Stand Development in HC-110

The use of Rodinal is most common with Semistand Development. I've been playing with Semistand development on and off for a while with the more common Rodinol.

Yesterday I gave HC110 a try. And I liked it.

Dilution: (from syrup): 1:120
Temperature: unmeasured
Prewash: time unrecorded (maybe 5 minutes)
Time: 40 minutes
Inversion: first 30 seconds or so, then one more time roughly 20 minutes (half way) into development

Equipment used: My old trusty JOBO 4x5 drum, Kodak HC-110 (duh!), Lauder fix, lots of water
Film(s): these show only Fomapan (Arista.edu) 4x5 samples, but the exact same shots were done with outdated Agfapan 100, Kodak Plus-X Pan, and Tri-X professional (320)

Camera: Toyo (Omega) 45d with Fuji Fujinon 250mm f6.3 and Caltar IIn (Rodenstock Sironar N) 150mm f5.6

Scanner: Epson V700

All in all, I was quite happy with the results. Density of negatives was pretty good. I actually shot two of each motif on four different types of films and processed the other stand in Rodinal. In some of the negs there was reduced density near where the neg touched the reel. But far enough out to print- I wish it were not there at all. Very little unevenness to be seen away from areas that touched the reel.

Grain was fairly heavy, but I think less so than with Rodinal. The unexposed areas had notably less density (fog) than Rodinal.

Linhof Serial Year List - Salomon Says

Recently I've acquired a few Linhof cameras. I got a 5x7 view camera from Oakland Museum's White Elephant Sale. Later I stumbled upon a Color Kardan 90 Jahre Jubalaeum edition on Craigslist. And more recently, I found a "baby Technika" 2x3 (6x9) at Oakland's East Bay Depot for Creative Re-use. Not knowing much about Linhof large format cameras, I tried getting more info online, and came across a strange thread on the Large Format Photography Forum . Basically on this thread various Linhof owners ask a guy named Bob Salomon what year their Linhof was made. And the thread is over 100 pages long! Sifting through that thread is mindnumbing. Why Bob doesn't just publish the list of serial numbers is beyond me. Maybe it's just nice to feel needed. So I started compiling a spreadsheet of the serial numbers and the answer Bob gives. If you don't feel like spending a couple days reading this thread to get a hint as to the age of your Lin

Lossy DNG File Sizes by ISO.

Fairly recently I discovered the magic of lossy DNG's. My stock photo library is ever growing. Though JPG's might really be enough for my archive, I've been keeping my raw files. RAW files take up lots of space. And RAW files can't typically keep user generated EXIF data in the file. RAW files keep their keywords and other metadata in a sidecar, that is if you regularly save the EXIF data to file. So recently I've been converting all my RAW files to lossy DNG's. After testing the highest ISO setting on the new-to-me A7R IV, I converted the files to lossy DNG's only to find a surprise. The very high ISO lossy DNG's were much larger than the original Sony RAW files! Lossy ARW vs Lossy DNG full image sample So I thought it would be a good test to shoot from the lowest to highest ISO, convert to lossy DNG and see where the file size savings invert. Here's the data as seen in the above screen shot: ISO Lossy Sony ARW Raw file size (MB) Lossy DNG file siz

From the Archive: Obsolete Film Data Sheet Scans - ORWO Information

Here's a sheet I got from writing ORWO Technischer Kundendienst back in the 1980's. It lists development times for all the ORWO Black and White films sold for export at the time (NP15, NP22, NP 27) combined with western developers Microphen, Atomal, Rodinal, Refinal, D-76, & ID-11. A little bit of ORWO history- Germany's big photo film/paper manufacturer up until Germany's losing WWII was AGFA (short for  A ktien G esellschaft F ür A nilinfabrikation - or corporation for some sort of plastic manufacture.) Germany was occupied by the winning powers USSR/USA/GB/FR and the rift between the USSR led to some complications for industries. Depending on your view of history the US and western allies were much friendlier to the land they occupied (remember the USSR lost many millions of their citizens to the NAZIs which made them much less tolerant.) In any case, some factories in the east moved to the west with many key employees. Most photo enthusiasts know of the t
