The Aero Ektars were made from glass that is mildly radioactive. However, given the size of this one, you might want to be careful with it.

The Aero-Ektars were made with mildly radioactive glass. Nothing too serious but worth keeping in mind as you play with it. You might want to keep it away from the kids or the grandkids. You can...
While you won't steal the lens from KEH, you will get an honest appraisal of its condition by people who know what they are doing, absolute assurance you will see the lens after you send in the money...
I presume you know these lenses are mildly radioactive. Not a super big deal but worth being careful with. Lots of posts here on the subject.
Good luck,

It was a nice Sunday in NYC and we went to the International Center of Photography. There were a number of interesting exhibits there but the one that got my attention was by Miroslav Tichư. All...
We had a long thread on this a couple of years ago. The issue is are you trying to make something that will cost you less than you could buy it for or are you trying to build a lens for the fun of...
I recommend that you try to see some of his images in person. Looking at them on a website really misses what they are all about. The compelling feature is the quality of the images and their...
It's more than life size. Roughly 4'x6'.
Yes, that was the photo. In person the details are amazing, like no print you have ever seen from a negative. The ICP exhibit was quite interesting but I am a fan and go whenever they have a new...

It was a sunny day in NYC and we visited the International Center for Photography which we do on occasion. There was an amazing photo there made by Richard Learoyd where he used a room-sized...
For years I used the stamped metal wrench made by Toyo. Rodenstock also makes one. I've also used the wrench made up of two vertical rods with drilled holes for cross pieces. This last one is...
Size, weight, focal length, aperture, manufacturer, coatings, contrast, bokeh, price new and used, filter sizes, lens cap sizes, resolution at different apertures and at different places in the image...
If you are handy with a soldering iron, another low cost possibility is an Omega enlarger power supply. There are a couple you could consider. The first is their Chromegatrol that has a...
The Toyo is built like a brick s___house. It will do everything you need a camera to do and your great-grandchildren will be able to use it (if anyone still makes film then....). I love mine and it...
Guys:
Thanks for the help. I think I'll give it a try.

Has anyone here tried Tektol as a paper developer? A search comes up empty. The folks who make/sell it claim that it is the photographic paper version of Kodak XTOL, e.g. a low toxicity developer...
Thank you all for your advice. I will give TMAX 400 a shot on my next trip.
Dave B.
Folks:
Does anyone have any idea how TMAX 100 pushed two stops compares with TMAX 400 processed normally? If you never need to go beyond an ISO of 400, is it worth carrying two types of film as...
yes^2*
* yes squared for all you english majors out there....
This now has a new home.
They are worthless and dangerous. If you had one in your house you might be tempted to take pictures with it and that would start you on the road to perdition and financial ruin. You should send it...
I found one on Ebay. It is a Beseler 45 lensboard. Still available if anyone wants it.
I have a lens plate for an unknown enlarger. It came attached to a lens I bought. The holder has a flat, square blackened aluminum plate that is four inches on a side, it has a raised top-hat that...
I have this lens. It is an amazing lens in terms of performance but a real beast to use. It is large, heavy and won't fit into some cameras as mentioned above. Other smaller lenses such as my two...
Some of us have learned how to use our tongues to trip the shutter. Fingers are pretty crude in comparison with the sense of touch and feel you can get with your tongue. It takes a few hundred...
The wavelength of light is too small for something like this to work. The films need to be a fraction of a micron thick, accurate to ~2-5% and uniformly applied over the entire lens.
This is a hard thing to do correctly. The first issue is single or multi layers. You need to decide what stack of films and materials you want to use. Issues that need to be considered are finding...
IMHO, whatever you shoot, you should bracket every shot +/- 1 stop. You might decide to initially only process the shots you think were on the money wrt exposure but having those other sheets of...
Won't it last four times longer?
The deterioration of film is a chemical reaction. Chemical reactions are speeded up at higher temperatures and slowed at lower temperatures. In general, the lower the temperature, the slower the...
Guys:
Thanks for the input. The Beseler it is. Gem, I was (he sheepishly admits) thinking about buying the equipment new. I have not had much luck with electronics that have been sitting in a...
Folks:
I've lost my mind and am planning on building a darkroom while the rest of the world is abandoning them in droves. The main reason for doing this is that in ten years it won't be possible...
Folks:
Thanks for your replies. It looks like this is the way I will go.

Folks:
I am in the process of setting up a new darkroom with a Jobo CPA-2 processor. The Delta ABS sinks look pretty nice and was thinking about getting one, probably the model with two sinks, a...
Photocraft in Boulder gets my vote (and my business). Totally professional.
This is an interesting comment. I always assumed that glasses were optimized to focus at a hyperfocal distance and then worked OK from there to infinity. Does anyone know if they actually do this...

It may be my imagination but it seems to me that the usually congenial nature of this forum has recently been replaced with a lot of generally unpleasant behavior. When even kindly old souls like...
If you are going to buy/use these types of polishing powders, you need to use a mask and be very careful about breathing the dust. The long term health hazards can be similar to those one finds with...
