Haven't maxed out the possibilities of my K-3 yet so I will be a while before I am ready for something else. (Had the unit since introduction and have been shooting Pentax since 1963)

Actually, Asahi optical started in 1919 so it did not start after WW2. That was when it designed one of the first successful 35 mm SLR's.

Tri X and Tmax 400, depending on clear skies or overcast and rain.

For more contrast, try extending your developer time about 30%.

Exacta made a fully lefthanded camera in the '50's, Left shutter, left wind lever. Heavier than a brick and very clumsy to use. Not because of the lefthandedness. Konica had an optional left side shutter release on the FT-1 model. Had a built-in motor drive as well. Easy to load with one hand. I set up several veterans with right side disabilities with that unit.

You only need releases for commercial work. News is exempted from the need to get a release. Imagine trying to get a bank robber to release on a security camera image for the 5 o'clock news.

Rechargeables are not a good idea. They generally are only 1.25 volts per cell and that leaves the camera at the edge of no power. .

Ken Marcus was known for shooting Pentax 6x7 for Playboy in the '80', as I recall.

I did some shooting along the Southern California beaches years ago. Three cheap Frisbees worked great to keep the tribod stable on sand and on iceplant.

Also keep in mind that commercial Hyperfocal charts are calculated on a 4x enlargement; ie, 35mm film to 4x6, 4x5 to 8x10. The larger the print, the more critical the DOF.

Even older color neg film had more DR than could be reproduced on the papers of the time. Some time about 1990 a young lady brought me a negative on Kodak Ektar 100(?) that her photographer friend shot. It was of her engagement portrait including her fiance. Sunset shot, backlit, no fill on the Southern California coast in August. With a substantial amount of Pan Masking film and several days in the darkroom, I gave her back 11x14's that showed detail from his dark slacks to the sunset clouds in the background (about 14 zones.) So, in my experience, it's not that film doesn't have the ability to record a large range but that ther is usually no easy way to reproduce that range.

Four and a half stops might be reachable, but I doubt it in everyday situations. I am not a big lens shooter, so take my views with a grain or two of salt. I find in most situations with wide to short tele lenses, in-body stabilization gives me consistently two stops, sometimes more. In non-scientific tests, I got slightly better results with in-lens stabilization, not noticeable in most circumstances.

Actually, inverse square law is simple. If the surface is twice as far away, it gets one fourth the light. So, 4 feet is f/11, 8 feet is f/5.6, 16 feet drops to f/2.8. The problem arises when the photographer starts using light modifiers, (umbrellas, softboxes, etc.) as the inverse square law applies only to point light sources. As a rough rule of thumb, you can expect that twice as far equals four times the power.

This was with an orange filter (O2.) The overcast was so heavy that pretty much all the light was blue, not a lot to differentiate. The boat was moving fairly fast so I only got three shots. This was my first foll of Acros, so I probably will have to change delveloper dilutions or times or agitation.

The apparent grain in the sky area is probably due to the PP to get the clouds to appear as ominous in the shot as thy did to the eye. This was my first time scanning Acros so I probably have some tinkering to do to my workflow.

Took my 645n/75A for a walk along the lake. Found this beautiful classic yacht under the Freeway Bridge. Acros, Rodinal 1/100, 18 min. Just scanned, be a few days before I get into the dark with and see how it prints.

Summer has truly ended, not that it was that great this year. At least when Seattle is doing the Seattle thing, the K20/kit lens are up to a walk thru Volunteer Park.
