I get the feeling I'm choosing paint colors at Sherwin Williams.
The use of forming gasses such as heated hydrogen, nitrogen, or a combination of the two, were effective at not only increasing the speed of plates, but dealing with reciprocity failure since the...
MirekM, welcome to the Large Format Photography Forum. You will find many different temperaments here. Some members are very inviting, welcoming, and encouraging with their comments, while others are...
As others have said, I purchase and use Gaylord archival products for storing glass negatives at the museum where I volunteer as a photo preservationist.
When I make still lifes, I place 1000 watts of halogen light two feet from the subject matter, and it still takes two full minutes to properly expose my wet plates at f/8. The faint light you would...
If you are new to wet plate, you'll learn that there are a number of different collodion formulas available. I've used the cadmium-free formulas of the two-part collodion + iodizer mixes from both...
There is an ebay seller (to whom I have no connection) who sells a modern interpretation of historic head braces for wet plate work. They are not the heavy iron stands we might like to have in our...
John, you've made some cogent points. As mentioned above, the first fan is positioned over the space where I perform my fixing. When I set this up, I tested the uptake draw with a tissue held beneath...
For fresh air intake I use a light-tight vent installed in one of the darkroom's two doors. For exhaust, I use 6" duct tubing that hovers above the sink where I tend to do my fixing. The duct is...
Let's see, where did I put my tin snips... I know they're around here somewhere.
That's going to be a bit difficult with a tintype, LOL. ;)
Lo and behold, I think I may have solved my own problem. By way of background, last October my father-in-law passed away, and I inherited his large camera collection. It consists mostly of MF...
Yes, it does.
No, I'm not. These will be frontal shots of relatively flat, metal objects, so DOF is not a significant issue, especially if the lens can be stopped down.
Since these will...
Thank you Oren. Although the decorative objects I'll be photographing are relatively flat (thereby reducing DOF problems), I'll still be so close that I may need a lens that can be stopped down to...
Luis, I found this thread here... an interesting read, and I like the close-up image that's included (but don't know if it's a crop).
...
Luis, that's an interesting suggestion. After checking the 'bay, you're right that it's much more accessible than some of the lenses previously suggested. And for ferrotypes I'm not preoccupied with...
Yes, you've made that clear, but buying another 5x7 camera isn't what I'm after. I thank you for sharing your opinion all the same.
I recently looked to see if I could find an extension rail appropriate for my particular camera, and have not been able to find one. I did, however, find someone who makes lens cones that I may be...
Thank you for the suggestions about lighting; I appreciate your thinking about it and offering suggestions, but we're getting off topic. Metering won't be involved and neither will light boxes, since...
Between my Speedotron pack and heads, not to mention halogens, lighting is no problem, and the shoot will be staged on my 4 x 8 table top.
Oren, would the Schneider lens that fits the bill be the Symmar S?
Thank you; this has been very helpful.
I have a 14-inch bellows draw.
Hello all, I need to take photographs of various decorative objects that range from 4 to 6 inches tall and about two inches wide with my 5x7 field camera, and I'd like to fill most of the negative...
Kyle, I think you've either contradicted yourself in your response to my post, or maybe you misunderstood mine or the original poster's (unless I'm missing something). When speaking about the two...
Since your son said, "assuming they are set at the same f stop," did you assume the opening for an f/8 Waterhouse stop for a Petzval lens would be larger than the opening of an iris stopped down to...
Wow, that's nice to know. I just sketched my plan for the box out on a sheet of paper, knowing what the maximum size of my prints would be (plus a little bit of wiggle room for my hands inside the...
I built my UV box this week with a useable interior surface area of 19" x 26". Here are the parts that I used, along with their dimensions and some assembly notes (everything other than the lights...
I'm so glad this site is back up. I joined in 2014 and missed having it as a resource while it was gone.
That's a great update that Tim made, and makes perfect since for Pt/Pd prints and other developing-out processes. I should consider the heavy glass sandwich as an alternative to my 11x14 print frame...
Russ, see previous post to answer your questions:
I can empathize with that. It's one of the reasons I have long absences from this site. Randy, I've enjoyed your posts and experimentation over the years, and am glad you weighed back in. Thank you.
I think that's a good point to raise, Russ. I suppose this consideration needs to be balanced by the advantage Tim Layton has described as reducing the exposure time to avoid the solution drying out...
Sure... actually, Randy provided a link on his March 19th post in this thread. It's a link to Tim Layton's article about how he swapped out bulbs for bars in his existing light box. The article at...
Uh - OK.
I guess there might be something amiss I'm not aware of; sorry if I've raised a pain point for anybody. I was just following an engaging thread as I finalize plans for my own UV box.
...
Randy, I'm bumping this thread to ask if you put the LEDs to use, and what your experience has been.
Thank you very much! It's a quiet little spot called Hunterbrook Cove.
Thank you... no preflash.
