The TLR on the left could be 100-700 - can't really tell from the photo.
10 film holders at 5-10 each
One of the other holders goes for 50-80, the other is worthless.
Case 20-100

I think that you are incorrect about vapor chamber cooling. Nvidia adopted it rather than invented it. GM, RCA and NASA all contributed to the development of the technology, long before the PC...
Certainly looks DIY with those cabinet pulls as handles and that focusing knob. I'd guess it is also fiberglass rather than carbon fiber. Sorry not to be able to figure out more. How do you work the...
What are you talking about 100K file limit? I just tested out uploading a 30MB file - no problem.
Microsoft's skydrive gives me 25GB for free...
Ready now.
Effective f stop as you calculated is based on extension so it is the same as bellows extension. Using both would be double counting.
Did you mean quota?
Leigh,
Surely you are aware that the geometry of any given lens design scales with focal length. Because the angular coverage is similar across different focal lengths of a similar design,...
It does happen on 35mm, but generally there is enough coverage that you don't notice it except for light falloff in the corners when wide open. Lenses are lenses no matter what the format.
In my opinion a crown is good for environmental portraits as you can handhold it and use the rangefinder + wire frame and get away from need for a tripod.
As others have mentioned, the...
Anyone seen one of these on ebay or surplus shed?
The problem is probably going to be finding the film loader.
More details here:...
Correct, but the making of those miniature-looking shots is using that principle to minimize the intersection of the image plane with the subject plane. Or more precisely, to select an image plane...
I'd hardly say it "clearly surpasses" as both lenses produce excellent images. The one thing the f/8 has overwhelmingly in it's favor is the smaller size and weight.
I've personally found that good engineers are quite aware of the fact that the models they use are quite approximate and abstract and that there are limits to their use. They realize that things like...
If they got there from any amazon link on your blog, anything that they purchase during that session will be credited to you. You can see them in the orders report in the "All other items ordered"...
Great! Thanks to you I'm back on.
Unfortunately I lost about $100 of ad revenue in the meantime :-(

You might try sticking a center-finding ruler on a parallel rule (mayline). They are easier to deal with than t-squares.

Well, those are...
Darin,
How are you getting those Amazon links working for you? They recently cut off the affiliate program for people living in California. If you have a work-around, please let me know.
It appears to be more about words than anything else so I'll base my commentary on that. For example:
"From time to time I would like to share books that I am reading, want to read, or which have...
I fail to see how changing the material on which the image is captured makes an impact on the understanding of how to compose a well framed shot. Painters work with composition all the time, and they...
It could very well be true. Try it and see.
Just because someone points out that there are major advantages to digital for commercial photography (and there are advantages elsewhere) does not mean they are driving nails into the coffin of...
Celluloid film anyone?

Film stock is lost and tossed every day. Almost all of the color...
Wrong in so many ways.
The argument that because digital is common it will become worthless has no basis. Photographers earn money because of what they do, not what technology they use to do it....
6 1/2" Ilex Paragon on an Anniversary Speed Graphic + 4 film holders. The whole thing cost me $35 in the early 80's.
With one piece of brass you can turn out a dozen different sizes in about half an hour.
For a 55mm focal length, extend the bellows 55mm from the focal plane.
The commercially made pinholes are pretty expensive. I've built my own using the following process.
Get a sheet of brass...
First, f/64 is a small aperture, not a large one. Note that the 64 is in the denominator.
The reason that diffraction is more of a problem at smaller apertures is geometry.
Diffraction exists...
Different tools have different "basics". Determining exposure is no longer essential (hasn't been since cameras had meters built in a few decades ago) and is done better/faster by the camera than by...
Where to begin? I think you are over-inflating the argument. Many of these concerns are completely irrelevant to platinum printing. For example, how many people are using platinum prints during legal...
If you are always using the paper for focusing, consider gluing a bit of it to the bottom of your grain focuser, or tape a flap of it on that you can flip underneath. Best of both worlds.
I do this quite often. Never had a problem and never was confronted by security. You can either ask first or explain when (and if) security shows up. Asking first is less likely to work.
I think he probably had seller's remorse or got a better offer. Oh well...
The dlsr is reading light at the sensor plane - so there is some loss through the lens and perhaps a bit of bellows compensation required unless you are focusing at infinity. Both of those together...
I guess I'm wondering why your comment about invalidation, bickering etc. appears to be aimed at me. I thought my comments were fairly balanced. The fact that I used the word burn as you did a few...
Actually, it is offset to allow symmetric rise and fall while keeping the standards short for folding/collapsing. If the hole was centered then both the back and front would have be located higher...
Practice is only useful to the point where you stop learning/growing and only when it is in a direction that you want to go.
A writer could practice writing the alphabet or copying sonnets for...
I wonder if the original poster has already given up LF in the past three years :-)
More or less evenly. There will almost always be fall-off at the edges as the light is at a more of an angle to your eye there. Move your head side to side and you will see the brighter area shift....
