I am currently working on two Luna Pro (the original).
One has factory battery conversion and came to life after I repaired the obvious battery chamber issue (Corrosion ruined the tip of the...
You can get apps for your phone that listen to the microphone and graph the click bzzzz clack and the time between can easily indicate 1 second to 1/10 second accuracy.
In case you want to find...
Regarding the idea to "mount the step wedge to the translucent sheet and focus at 1:1"...
Some people do it that way.
But the image of a step-wedge starting with 1000:1 contrast, after...
I agree with Mark Sampson it is the best light source I have found for Omega DII / D2. It's very useful.
So far my luck has been good. Of all the Galerie paper I have bought online, only one box had any significant fog. And it was a box the seller threw in for free.
If it has fog, I'll use it for...
In a panic, I just snapped some up off eBay. 11x14 little less than a dollar a sheet.
For better or worse at this rate I'll take my chances.
Then there was the time my son held the back of my belt as I leaned over the cliff.
I was using a rangefinder so all I had to do was compose and shoot. The focus, f/stop and shutter speed were...
I'm guessing Minor White drew the hand/lens logo. It's his style.
I saw him at Caltech. I think it was a high school field trip.
Looks like it works!
Can you show us your tiny space? Maybe there's a dry space option you haven't considered.
I can't imagine not having enough room for at least two 11x14 trays... Dev and Fix. Then take out to the...
I like the thought in what Paula Chamlee said about looking at the groundglass... "see the world for how it looks versus how it is."
Maybe this is where I have gone wrong by shooting a...
It's definitely the one to get if you don't already have it.
That would be sweet! Can it refocus... say if you aim at subject's eye, recompose but they move slightly back, you'll re-focus on their eye because the focus aim followed?
Here's some of the HAER photos of the radio stations...

I was thinking going inside, getting close-ups of the gear. Didn't one of us do that?
Please make sure you have enough water.
Also take the keys to your car. We had a friend leave them in his friend's car glove compartment thinking it would be fine. It was but his friend's car was...
I don't know if a brighter bulb would hurt!
Thanks! Got the data from your spreadsheet! I like to remove B+F when graphing, but BTZS wants you to include it. Ralph Lambrecht also has a spreadsheet to accompany Way Beyond Monochrome which is...
It took about 10 minutes to get the image density built-up by normal developing... how much additional do you think happens in a few seconds? Not enough to measure.
Alkaline fixer is the...
mpålsson,
You say you saw: "ISO triangle came out to be very close to the 13’30” curve"
That's the developing time I get when I meet the ISO triangle for TMAX 100, TMY2 and TRI-X in D-76 1:1....
I've joined the discussion from time to time... There are lots of complaints about the light, I know.
Be sure to judge the bulb in light levels so low that the spot you are reading has a scale...
One day you will be facing a deadline (like a friend's birthday and you want to give them a portrait), on your last batch of chemicals, and all the camera stores are closed...
If you have a sensitometer and densitometer, you can figure it out. Practically everyone has said it's not worth it and I agree.
But I have done a similar test and know how to do what you are...
It is the reciprocal, and you want the square root of the arithmetic film speed. And right Weston meters indicate candela per square foot. Shutters mostly leave off the 1/ . If there is time the...
Right. Since a Weston Master indicates that:
Take the square root of the film speed and use that for your f/stop.
When you have taken an average reading with a Weston Master light meter...
Set...
There is an ugly one on eBay for under $100 - worth the experiment!
I got a Bausch & Lomb 4x5 Protar V 3 1/2 IN f/18 for the purpose of experimenting in the style of Bill Brandt
Think he used 5x7 film in his old detective camera though - which would take in more...
Ansel Adams tells how to convert foot candles to f/stops and shutter speeds in your head.
Use the square root of the film speed for the f/stop and use the footcandles for the shutter speed.
Haa exactly! Used to have a reverse osmosis filter and this served well for the final rinse. But after a couple leaks I decided I didn't want to take any more swim tests and I shut the thing off and...
@jp I like the precision/accuracy scale. The one with no precision and no accuracy should have fewer marks on the target though (because some will miss the entire dartboard).
I see I fall into the...
Tape the Stouffer strip to a 4x5 piece of black construction paper with a stripe cut out of it to let the light through the strip.
Just don't use those orange capacitors that Nakamichi used in their cassette decks. Use the capacitors that EG&G used in their sensitometers.
I recommend Yes! A Stick Flat glue. I keep this paste in my finishing box.
Takes a bit of practice but is quite good fo an occasional mounting
Are you sure the bulb is not in there? If it is not there you will see a hole where the bulb would go. You could aim a bright flashlight in there. If the ammeter needle moves, even just a little, you...
Nice - box too! I've been watching for one of these, didn't think further into what would happen if I lit it.
I made the same mistake Stearman. Anyway develop it more than 9 but less than 13:30 (I develop all my film too long compared to most other people) and you'll be fine.
The LEAH telescope at Chabot Observatory has Graflok back.
OK I see 9 minutes in massive dev. They don't track aim contrasts so it's hard to tell. I use tray with several sheets shuffled. That extends the developing time because each sheet only sees fresh...
