I am using a Besseler 23C enlarger to print B&W.  The condenser head
has a 75 watt bulb in it.  My problem is that this setup is too fast.
For a typical 8x10 on Ilford Multigrade FB, an exposure time might 
be 10 seconds at f/11 for a 35mm negative (50 mm enlarging lens.)
I would like to be printing for about 30 seconds for repeatability,
to do burning and dodging, etc.  Also, I would prefer not to print 
everything at f/16; I know this is not the sharpest aperture I could
use.  Does anybody else have this enlarger and notice
this problem?

I see two possible solutions:

1 Get a lower wattage bulb.  Does such a thing exist?
2 Get a neutral density filter and throw it in the filter drawer.

Suggestions or comments?

And 3/8" BSW for larger units. The only other common mount I know of is the VHS
mount, 1/4"BSW plus a pin to align the camera with the mount.

Yes. Expose T-Max 100 for EI 64 (at least that's what I use -- I expose
APX 25 for EI 12 or EI 16). Develop at 24C for 6 minutes in a Jobo
rotary processor with agitation "P". Use Rodinal diluted 1+50. The time
will probably have to be lengthened somewhat when inversion processing
is used.

I recently returned from a weekend in Zion National Park.  While there, I
decided to pit Ektar 100, Fuji Super HG100, and Fuji Reala (ISO 100) 
against one another.  The results were not even close.  The grain
and color saturation of the Reala was leagues above the other two.  In fact
the Ektar produced bland, flat looking pictures.

When shooting prints in the future, I'm going to stick with the Reala.

You should ive "Reel 3D" a call.(310) 837-2368

They carry a number of books on the historical aspects of stereo photography.
Of course, if you decide you want to make your own... You could pick up an
old Stereo Realist or Kodak stereo camera.  They are plentful and relatively
cheap ($100 - $150).  Reel 3D carries mostly supplies for the stereo photographer.

They were going for $600 for most.  Two were $750.  The gallery owner was
busy with paying customers and had been quite nice about answering my
other questions so I didn't want to interrupt her any more to ask why the
two cost so much more.

Uh.  After doing some cost estimating on everything from a 300mm enlarger

I am thinking Mamiya 6. But unfortunately, I cannot find any Mamiya 6

Please help me.

Question 1 for Mamiya 6 experienced persons.
	How about the followings.
	- Lens quality (Contrast, Resolution, Flare, Distortion, etc)
	   (If possible, comparison with Planar 80/2.8 of Hasselblad)
	- Operation (Film Loading/Unloading, Focusing, Finder, AE accuracy)
	- Weight
	- Shutter Noise and accuracy
	- Internal body reflection

Question 2 Mamiya 6 rental shop
	If there's a rental source near San Jose, please inform me of it.


THank you in advance.

PS. Street price of Mamiya 6 with 75mm lens here in US is around $1,800. In Japan
it is sold at 140,000Yen(Less Than $1,200) according to Japanese magazines. 
Why this difference?  Mamiya controls US price?

Just out of curiosity - is that really considered a good price for Kodacrhome
in Canada? It's really high relative to US prices. Kodachrome can be had by
mail order for about $6 US (about $7 Canadian).

I made what I consider to be one of my better images on the beach at
Point Lobos; it's a moderately large rock bed with an incredible
arrangement of rows of 5" wide tidepools in it, separated by 5" of
rock.  Later, I bought a book of Edward Weston's photographs, and found
the same rock.  My photograph is better, of course -- he seems to have
missed the obviously superior composition.  ;)

However, it's still his rock; in fact, it's his beach.  In fact, it's
his Point.

Someone asked for the address of ready-made platinum printing paper.
A source for palladium-platinum paper is:

   The Palladio Company, Inc.
   P.O. Box 28
   Cambridge, Massachusetts  02140

   (617) 547-8703
   Orders: (800) 628-9618

 I have not used the product, but did get their instructional/promotional/
 ordering brochures one time after attending a talk by a photographer
 who uses Palladio products. (I do not believe he was affiliated with
 the company.) 
 The Palladio paper has the virtue of being more stable than typical
 home-made platinum paper. It is also supposed to be quite consistent
 from sheet to sheet and package to package.
 The photographer I heard talk about this stuff seemed enthusiastic
 about Palladio paper. He had some good prints to show, so I guess it works.

I have recently started using Agfacolor Ultra 50 'professional' (whatever that
is supposed to mean -- thank you, marketing). I had brilliant success with it
for the first couple rolls, but I thought I would refrain from commenting until
I'd shot some more.

I've now shot more situations and I feel this is a superb color print film.
I consistently obtain superior results with it compared to Kodak Ektar 25 and
Ektar 100. Surprisingly, I have had better experience with Ektar 1000(!!) but
the grain is just too much for my purposes. 

To put this in perspective, most of my shooting is outdoors, natural light. 9/10 of
my shots are 1/60sec or longer, I almost always am using a tripod. I also do a lot of
shooting at dusk w/ consequently long exposure values. I also used the Agfa for
some hand-held portraiture at 300mm in full sunlight + some convenient reflected light
to soften the shadows. This produced some stunning results. I have also used it for
a fair amount of macro photography (typically 1/30 - 1/250s, again always on a tripod)
in overcast and shadowed situations with good results. 

If you do similar shooting, I urge you to try this film!

Has anyone tried these products? A dealer I visited today said that
the Multicontrast developer performed better for most RC papers

better than Ilford's Multigrade paper. The new Kodak polycontrast
paper should be something extra, he also said.

Can anyone confirm this?

For 35mm portrait work I've been very pleased with Kodak Gold Plus
100. I have also been very pleased with Fuji Professsional NHG 400.
Both of these have quite fine grain and are relatively low contrast
films, capable of excellent flesh tones.

Wisdom?  No. ;-)

Don't the Wein infrared things have some kind of a power saver mode?
Maybe it's going to sleep and isn't being awoken by your camera.
