It doesn't focus as close as I'd like for still lifes etc.

G'day Steven
Thanks for the info. I found a page at http://antiquecameras.net/rosslenses.html that shows what appears to be original Ross advertisements.
If I assume that the stated measurements...
G'day Jimi
I recently acquired a smaller brass lens and built a 4x5 box camera to fit it to.
These brass lenses, though physically large, have quite restricted coverage. I was planning on buliding...
G'day Ian, I'm with desertrat, don't give up on paper negs. I've shot thousands in the last 10 years and love it. Yes it can be difficult, yes the results are unpredictable, often a shoot will...
An interesting question Maris. But I'd turn that around and ask, if we never had chemical based photography would anyone have ever gotten the idea to make images digitally, or at all?
Search in the old posts Steve, I've posted lots of stuff re making mine out of 3mm MDF and or ply.

You must have strong eye sight to focus with a film holder inserted?
G'day Tony, I'd suggest that you need to try again with known materials.
Because, in your diagram, can you see that the camera body for the 300 mm lens will need to be, physically, twice as long to bring the image into focus at the film plane.
So, the same amount of...
G'day O,
I like your printed ground glass holder.
To what size do you think this would be a viable method of production?
As for where to put the GG after focusing, I'd suggest building a...
G'day Neil,
I've made quite a few from 3mm MDF.
Mine are single channel, meaning that the dark slide runs in same channel as that which holds the film.
I've made them in several sizes; 5x4,...
Beautiful Alex, I knew it was yours before I saw your name attached. Like your other works, not just special because of the materials, techniques or tools but special because it is a great image.
Hey Tony, I'd say you are totally wrong. FB curves to the emulsion side, RC curves to the non-emulsion side.
Don't sweat it, do a test, mark one side of a sheet of paper corner to corner, cut,...
Looks like contrast is far too harsh. The nicely lit bridge in the distance has exposed nicely but the dark foreground is grossly over exposed. Forget trying to 'improve' results
by varying...
I assume you don't have an enlarger, is that correct?
Your flash will probably be too powerful and you will have to control output somehow. Then arrange some means of doing a test strip but you'll...
Still not understanding Vic. Why not fix, how does not fixing help scanning? What happens in a few weeks when the image browns and fades?
Yep, have a go Tony.
Regarding development time - my understanding has always been that photographic paper should be fully developed for at least the recommended time. Pulling a print when it...
Nicholas I do pre-flash under my enlarger with no contrast control filter.
I've previously done test strips to determine the exposure time just short of causing noticeable fogging.
Here in...
G'day Tony, seems to me you've got a lot going on; images are quite blurry, negs seem to show light leaks, negs are under exposed and contrast is too high.
Perhaps your concentrating too much on...
Shoot some pictures, check out the results, what do you think?
All my LF lenses are somewhat simple and cheap.
I'd suggest a large magnifying glass, I've got a few that measure at around 350mm focal length.
Or get an over head projector lens, they are...
Don't forget that its more important how you use it then what you use.
You've elliminanted one because its the wrong 'priority', you do realise the one is tied to the other.
Just make negs Tony, you'll soon learn that ISO varies depending on the time of day, amount of overcast, how you process, if you use filters.
My preferred is to avoid high contrast lighting...
Looks pretty good to me. Paper neg has its own aesthetic. If you want sharp, good contrast, full tones, etc, shoot film. Paper neg is something else.
Nicely put Mike, I totally agree and would add that film is meant to be printed.
Beautiful work Damian, your subjects come across as real, genuine and honest.
Thanx Jac, quite a lot more.
So who bothers?
G'day David
I wouldn't bother.
Those few who would appreciate the subtleties of monochrome tonality would be hard to please and the rest would'nt care.
I recently dug out some old 35mm slides dating to the early 1980's. The Kodachromes and Ektachromes look great, the E6s are in pretty poor condition. All were kept in the dark in dust proof storage...
I scored 2 of Robert's beautiful images.

G'day all
I've been building sliding box simple lens cameras and film holders for about 10 years.
Just have a go.

thnx Robert, the link works fine, great works, I'd very much like to own one
Is it just me who can't find the FB page?
A beautiful image Alex.
"... hard to do?", what would that matter to you.
I'm not sure what your formula means, maths is not a strong point of mine. I just convert focal length (measured when focused on infinity) to dioptres, add the dioptres and then divide into 1000 to...
Hi Wayne, I've not got any commercially made 8x10 holders but I do know from experience with 5x4s and 5x7s that they are a few millimetres smaller than the sized paper as bought.
G'day Ned, great to hear that I was of some help.
Yep, single magnifying glass lens.
I'm about to test a composite made up of two magnifying glasses. I suspect image quality will still be...

A 5x4 paper neg exposed in homemade simple lens sliding box camera.
G'day Chris, as John writes you may well have induced camera movement. Perhaps it would have been better to reduce the ambient light and use an open shutter whilst firing the flash manually.
I've...
From my nearly 30 year experience I'd say that RC paper is more contrasty than FB when exposed through the same contrast filter. So, either your not really using variable contrast paper or your not...
