Tks Lenser, I see I can get the Time Life book, used, for a staggering $1.52 on Amazon. Looks like a good investment.
I have both the Kodak card and the Geta Macbeth X rite color checker card. I was...

Tks Erie, I am aware of the color temp change with power but right now, I need the lts on full blast. I need to get to f22 and I'm at f16 at best.
Frank, I'll remove the domes and try to find some...

Tks, no I don't know the color temp of the lights. I was hoping to borough a color temp meter. Profoto makes different glass caps for their strobes, I believe +- 300K and +-600K. I'm hoping I can...

That was fast Ron, many thanks.
I had looked at the Fuji data sheet previously but I still don't see the 5600K listed anywhere. Sorry to be thick, but could you tell me how you determined it was...

I'm shooting fine art with 4x5, Fuji Provia 100F RDPIII and Profoto Monolights. I need to correctly balance the film and lights but cannot find the exact color temperature of the film. It is daylight...

Thanks to everyone again, all your feedback is most enlightening for me as a novice to 4x5. I've reshot the art work being much more careful with angles and positions of both the camera and the...

Thanks, I set the whole thing up again. I think Sheldon and others hit the nail on the head. The painting was probably twisted requiring a small amount of front lens swivel. As you point out, on...

Tks for all your thoughts.
Sheldo, I checked Chris web site, very interesting. If I interpret your extract correctly,
(Rodenstock Geronar 150mm
f/11 60 38 24 ) I'd be getting less than half the...

Shot at f11 with a circular polarizer to eliminate the reflections (very glossy and textured). Studio lights full blast.
The lens is a Caltar 11-E, 1:6.3 150mm.
I also have a Caltar ii - N, 1:5.6,...

There is a lot of very technical info on this forum on DOF which looks really interesting. However I'm rather under the gun. I just photographed some oil paintings (60"x48") with my 4x5 and a 150 mm...

Great thanks guys,
With the cost of film and processing, you've saved me a few dollars in experiments.
Now I feel confident to shot at 1/250th without any concerns
Many thanks

I am planning some studio work with my Cambo Legend with 150mm, n0.0 and 210mm n1 copal shutters. I have modern Profoto 600 watt sec. monolights.

I've read that the light is reduced by about half...

Thankyou for your help. The fresnel lens does seem to fit nicely between the eye and the ground glass under the two spring clips. Alan, I understand your last point, I hadn't thought about that...

I have a Cambo Legend and I picked up a Fresnel Lens in a camera flee market that looks like the right boy for the job. Should it be fitted between the lens and the ground glass or should it be on...

Tks everyone.
The Noctures website is very interesting.
I shot a few sheets of Tmax100 in my lighted back garden this evening and will develop them Saturday. Fingeres crossed although based on...

I'm new to large format photography. I'm interested in long exposures but not sure where to start.
I saw the f4 rule (1/ISOx day) posted in this forum but don't understand why this doesn't take the...

I'm looking for a cambo legend, lightweight carrying case with big solid wheels that won't break the piggy bank. Does anyone have any recomendations pls.

I prefer to leave the camera assembled....

Whooow, what a great community. Thanks for all your fantastic advice.
I already picked up on Lousiville and all those highly relavant workshops but unfortunately I've a wedding shoot that weekend....

I have a lot of experience with 35mm, medium format and digital. I have been curious about large format for many years and have finally acquired Cambo Legend with 90/150/210 lens'. I have been using...
