Ooooh... now I'm getting excited. :)

If you try this you'll need to fix and wash the unexposed paper first to remove all the siver. Also, you may need to use a non-hardening hypo in order to keep the emulsion porous so the dies can...

I've put a lot of thought into this also. I chose a lens as the central point with a FL of approximately "normal"... a 300mm Fujinon-C. I shoot landscapes so I don't need a huge amoung of extra...

Your problem is you tipped past the "happy balance" point.

Ooooh... I would really be interested in a 4x10 system. Of course, a custom holder would be pricey.

Are you sure you want all three of those? I can see getting the 240 and 360 but the 300 seems a bit too close in FL to the other two. Of course, if the deal is good enough you can just resell what...

The Canham MQC 57 has more than 600mm of bellows draw. I'm thinking of selling mine with all the goodies including both the 5x7 and 4x5 backs, standard and bag bellows, etc. I wouldn't dream of...

Have a few beers and it'll all start to make sense.

Two year old thread but yes, well done :-)

Just add a couple of adjustment layers : first layer is original image, second layer is hue/sat with sat all the way down, third layer is curves (or similar). Save as a PSD with the new layers which...

With the cells removed first determine if there is a mechanical issue... damage or obstruction. Then clean with Ronsenol lighter fluid working open/closed (slowly - don't force them)... this should...

TOURIST COUPLE: "Excuse me, could you take a 'quick snapshot' of us?"
ME: "Sure. Where's your camera?"
TOURIST COUPLE: "Isn't that a camera?"

A reverse adapter was included in the lens kit that came with the MP-4 for odd situations but it's not worth mentioning, IMHO, because I consider it a pain to use. It screws into the back of the...

I agree with Drew. These are indeed fine lenses but, alas, way under appreciated so you can buy another one for a song.

May I suggest you remove the cells (front and rear) and try cleaning the...

I do tend to generalize too often. There are indeed exceptions to my statement and I should have written, "...no need to reverse-mount them (Tominon copy lenses) vs. using 'most' enlarging lenses.

The 17's are around but fairly difficult to find. I never had any issues with the shutter... quite good IMHO. The Polaroid Tominons are designed specifically for flat field copy work (or macro)......

Dan,

My native language is English. Did I say something offensive?

Symmetrical lens design only means the same number of elements in the same number of groups either side of the aperture. Shapes and spacing can be tweaked to better perform particular tasks. A...
