I note that Linhof Technika cameras have individual cams for each lens. Is
it truly critical that each cam have the same serial number as the lens?
Does anyone make cams or adjust cams to work with mismatched cams?
Any other comments regarding the cameras? For example, the earlier ...

The Humbler - Last week was one of those times where so much went wrong. A
real humbling experience. I got a consistent light leak in two good film
holders when working in bright sunlight with the new-used Sinar. See it on

When tray developing Tri-X, what size tray, what quantity of developer, and
how many sheets at one time is recommended. I'll be using HC-110 dil B or
D-76.
Thanks,

My latest find from *Bay just arrived: an old brass-n-chrome Bausch & Lomb
lens in shutter. Actually, I'm not sure just what to call it. There are three
names on it: "Victor" at the bottom on the aperture scale, Bausch & Lomb Opt.
Co. around the bottom of the lens, and R.O. & C. ...

   I have acquired another big brass lens: An Emil Busch Rapid Aplanet No.
5  Foc. 18 ins. (R.O.J.A. vorm Emil Busch A-G Rathenow). Built in iris with
f/8 thru 64 settings.
   It came attached to a Thornton Pickard shutter that seems to function

Many of the lamps in the old commercial contact printers are in the 25-40
watt range.  Try a smaller wattage lamp, maybe even a 15.  Look for a used
enlarging timer somewhere or pop for a new one.  You'll be glad you did.  A
Time-O-Lite with its auto reset feature is very convenient ...

My new toy - a 4x5 Crown Graphic - arrived late last
week, and I had some fun with it over the weekend.
I got it from B&H, who rated it 8 in their system.
KEH would call the camera "Bargain"-grade - obviously

I was fortunate enough today to ruin a negative completely. Now while
that may sound terrible, at least I had one now that I could use to
practise loading and unloading with. Today, I had the same jamming
trouble when attempting to reinsert the dark slide. After completely

     The way I understood it stopping down increased the image circle
because it improved the quality of the image. But then I found this quote
"4. Why does the size of the image circle in a Large Format lens change as
the lens is stopped down?

Good morning all,
So it's dawned a lovely morning here in the Ottawa Valley. The weather
was a bit frightening earlier with thunder and lightning storms moving
thru'. It's cleared up a bit since then and promises to be a bright day

Well !!!
From previous posts, you will know that I am slowly getting into LF
photography a bit, and am in the process of building my own 8x10 unit,
but....in the meantime, seeing as how 4x5 film is about 1/3 or less of

I'd like to build a simple lens for use with a large-format camera
using 'off the shelf' lenses such as those available from a scientific
catalog. Priorities are as follows (all are desireable - but 1 is most
important and 5 is least important):

Folks,
I'm researching my first 4x5 camera (been a 35mm part-time
photographer for ~35 years) for my nature/landscape photography (Mt.
Rainier NP and environs) and city/townscapes.  I originally looked at

Well, you've seen the post with a link to my first photo, which was very
much out of focus and (I think) overexposed. This evening, I had almost
exactly the same conditions as far as weather and light and clouds etc,
so out I went with my camera, spent about 20 minutes working ...
