The Miracles of Analog Photography

I'm 50 years old at the time of writing this. I grew up with analog photography being the only option.

In the mid 1980's when and where I attended Independence High School in San Jose California I had a fantastic photo teacher: Mr Bernucci. At some point he just gave me a couple of way outdated boxes of Kodak Medalist single weight photo paper. The paper expired in 1972, so obviously it was made a few years earlier. Funny thing is that this paper was likely made about when I was born.

The big yellow boxes once held 500 sheets each. One box was grade 2, the other grade 3. At some point my dad Hans was looking for a photo paper box to store my grandfather Milton (Hal) Halberstadt's ashes. Al Weber was doing a memorial workshop to honor my grandfather. So I consolodated the two boxes of Medalist paper into the same box face-to-face so I could know one stack is different than the other and gave a box to my dad. My dad would set up a folding chair and put the medalist box

Fast forward to today. I work as the "Photo Tech" at Mills College and often help out in the darkroom. Alice Shaw is teaching the darkroom photo class and often points students to me for unusual requests. One student was looking to crumple photo paper for some reason and that doesn't work well with RC. I offered to bring in my box of old paper (in a huge stack of old photo paper I've bought and/or collected over the last decades.

I came in and gave it a quick test. To my surprise the paper still behaved normally! There was real black and true white. The tonality looked good. The paper and I are the same age, but I'm wrinkly and gray, and the paper is fine!

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
