Actually Artificial Intelligence existed way before that. Alan Turing conceived of a test to determine whether Artificial Intelligence had been achieved in the 1940's.

I prefer the acronym Operator Assisted Failure ==> OAF Usage: The oaf poured in the fixer, emptied the tank and then the oaf poured in the developer.

Welcome back and please stick around this time.

I have found that developer first produces much better than fixer first. I too have made that mistake once but not in such a specular fashion nor with such flair.

Rob thank you. I look forward to seeing more of your work.

Well done with a clean & elegant design.

My Hasselblad repair man loads a spare roll of 120 film in the back with the dark slide removed. He advances the film to the first frame, takes a ball point pen and traces the outline of the frame on the paper. He advances the frame and repeats the process for each frame. Then he unloads the...

It all comes down to the lens prescription and how it was filled. I preferred contact lenses to eye glasses. I have had excellent progressive eye glass lenses that worked well with all types of eye glasses. The same with single vision and bifocal lenses. I have one implanted lens from a...

Correct. I used several of them as spacers for mounting a lens in the enlarger.

I get a pleasurable feeling every time a package gets delivered. If I go long enough between receiving packages, I start chasing USPS, UPS, FedEx and DHL trucks that do not stop at my building up the street. I do not know what I will ever do if and when I actually catch a truck. :P

Thank you. I was able to read the article directly. I have had similar concerns since the doctored photograph of the shark jumping out of the water attacking a rescue helicopter appeared on the internet years ago.

Best color saturation for a color negative film: Kodak UltraColor 400 [no longer made]

I like the Induro carbon fiber tripods. It is important to select a tripod that is "rated" for more than the weight equipment that you plan to use on it. I use a factor of two heavier. When I use a lower rated weight I have had shaking and wind vibration problems.

Please note that is not the same "white gas" as the unleaded gas of the mid twentieth century, so do not swap the usage.

"White gas" is the name used in the mid twentieth century in the US as unleaded gasoline.

I have found hard to source screws at industrial hardware stores. Sourcing small machine screws such as the JIS type are still hard to locate. Work bench practices such as putting all small parts in glass bowls or jars helps prevent loss of those parts.

I really need to take my Pacemaker Speed Graphic with a 135mm lens out for more exercise. And then there are all the flash bulbs I bought for it and never used.

I suggest that you cover the original hood with thin pieces of cloth on both side glued on with a very thin layer of Gorilla Glue which is flexible. Let that dry for 24 hours and then put something like the product below on it.

Personally I like the cuddy bears in Australia much better.

I hope and wish that he has a speedy and full recovery.

Yes Shutterfinger has stopped making Graphic and Graflex repairs and has become inactive on Photrio. He did some high class work for me but I do not know anyone to take his place.

The people that I will offer a print to are honest enough tell me whether or not they want it. Generally though they will ask me for a copy first.

The tie makes all the difference! Without a tie what will you drag through the trays.

I have an insulated backpack with slots for chemical blue "ice" blocks.

Are the import duties and VAT on owned equipment that has been repaired? I would expect that on new or used equipment purchased. If so, fly out to Los Angeles, take it to Hasselblad and you can stay at my place while you wait for the repair.

That is my experience. For some reason the brain is wired to "see" better in a darkroom or with a changing bag then with the eyes open. It works and I use it.

Welcome to Photrio! I love to see old cameras being actively used today.

My decision was between the Nikon D850 and the Nikon Z7 ii and using my Nikon F AF lenses. I was advised by my friend, a retired Kodak employee and recently returned from a trip to Antarctica to buy the Z7 ii because it has vibration control. Then after I ordered the Z7 ii and before it...
