[pinhole-discussion] MF pinhole

I am not sure if I am going to or not, but I just got an Agfa folding camera - mine is 6x9 but there are plenty of 6x6's. Many have seized-up focusing lenses. Mine has a messed up shutter. The lens came off fairly easily, after some research (you just need to know who to ask). I may convert it

[pinhole-discussion] 6x9 camera conversion

Hello: I picked up an Agfa Ventura 69 folder. The lens is filthy and shutter is stiff and maybe worse than just that. I would like to get it off for two purposes - Pinhole 6x9 of course, and to battle the lens/shutter if possible. I am puzzled abotu how to remove it - any experience with this?

Hello: Rescued more stuff (prevented demise in trash) from work. 1) 4 x 20 packs of refrigerated out-of date (2000) Polacolor 59 ER 4x5 film. I understand this stuff shifts blue with reciprocity failure as well as aging. Will a yellow filter improve this? Or should I just play with it? 2)

[pinhole-discussion] pinhole light falloff vs. circle of coverage question

Hello: If one set up a 4x5 bellows camera for pinhole with an appropriate pinhole for double extension (say 300 mm), placed the bellows at 300 mm but used a 4 x 5 filmholder, would that place the worst of the edge falloff outside the 4x5 image? It seems to me that this would work, at least to

[pinhole-discussion] Polacolor 59 ER?

Hello: I just inherited some Polacolor 59 ER from work - expired but refrigerated, and unfortunately spent a couple days in the car somewhere between 0 and 30 F - not supposed to freeze it... So, I guess I'll try pinholing it - and I hear it might also be an emulsion transfer or manipulative

[pinhole-discussion] camera conversion question

Hello: Gutted some Polaroid rollfilm cameras with 130 mm lens/bellows. Extends a little farther than that due to 3.5 feet to infinity focus adjustment. Pulled lens, kept shutter for experimentation on one. Rear opening of bellows frame is a hair larger that 4 x 3. I took some measurements along

OK - someone get out the tranquilizer gun I just did some calculations for the 18 x 23 bellows. 560 mm f.l., 1 mm diameter, f 560 gives me optimum conditions with 73 degree view angle, 830 mm film dimension and 1075 mm coverage. Looks do-able. I guess here's where I need the wake-up call.
