You get a more even spin if you use circular disks, but it'd be no problem to make a disk with an indentation to accept a rectangular plate, that should take care of most of that issue. But anyway, when I spin square substrates, I only see a bit of nonuniformity right at the corners. The...

Cool. More info on the type of spincoater I've been using may be found here: http://www.laurell.com/index.php It is possible to control pretty much everything with these, the chucks can even be heated or warmed air can be flowed into the coating area. I currently have the simplest version...

At "wildbillbugman" Bill's suggestion, I am hereby mentioning that I have access to a spincoater that can handle plates up to 6" diam. I spincoat quartz and silicon wafers with photo- and e-beam resist as a routine part of my research work. I believe that the technique may work well for film...

Even daylight balanced fluorescents have the big, sharp mercury ~488 and ~546 nm spikes, which cause problems even if the overall colour temp is 5000K. Those spikes can wreak havoc on the white balance. By and large, 400x really likes ~5000K light. If you are really concerned about colour...

I have no problem starting with the basics. But if we're going to do that, then let's go all the way! Your [taking] lens also has falloff, which leads to underexposure toward the periphery of the film ;)

I wouldn't push D3200 so much for 35mm, I tended to rate it much lower than 3200 anyway. But for larger formats, go nuts and let us see your results! I would *guess* that if you want to get 6400 out of it, you need to expose it for double time, i.e. meter as if it were 3200. My guess is...

You could perhaps print the area of concern a stop or two darker than the rest (with standard dodge and burn techniques) and then bleach that area selectively. Selective bleaching can really boost contrast a lot. Depending on your bleach, you can reduce proportionally or attack highlights and...

Yes I have never tried 400x except in natural light. Never even occurred to me to try- I use other films for that. For most applications with 400x (and any slide film for that matter), I would simply aim not to mix color temps or you're probably going to get a mess. So... if you have nice...

Oh, my apologies, I always get the Rodenstock Apo Moneygon confused with the Schneider Apo Digital Avatar XXL, which is actually more expensive but sports a much smaller image circle. Anyway, all of these tend to cause people to lose perspective in 3D. Mustafa, those childrens' faces are indeed...

Clive I am in the process of matting and framing a gorgeous print from you, it's a gem. Worth every penny and then some! I wouldn't dodge or burn a thing ;) But thanks for what you just said.

Well see that's why we need images!!!! :whistling: Some people allege that a particular lens is more "3D" than another, and others say: nah, I can do that with a coke bottle. So then, without visual examples, we all just talk past each other... and both sides get frustrated. Time for both...

Just my opinion of course, but I think GNDs are absolutely necessary for some scenes. At the same time, just as is the case with d&b, there are plenty of examples of misused / overused GNDs. If you can look at an image and tell right away that there's been heavy d&b or GND, then chances are...

Who said anything about validation? I just like for people to share their work and to show examples. My ulterior motive, if any, is to aim for more precise language, so that people can communicate a bit better about photography. But, as the saying goes, a picture is worth a thousand words...

A photogram is a photograph made entirely by d&b. Discuss :)

Let me turn this argument upside down and ask the obvious: what would you do to make an image look more two dimensional? I do that deliberately sometimes to get a juxtaposition of different shapes etc. I sometimes like for an image to look like a form drawn on paper. For me, to create a...

For hands, Avon SkinSoSoft works miracles with all manner of nasty substances ;)

Well then turn off your "walt disney calibrated monitor" and look at some real slides and analogue prints! By the way, I don't see any of your imagery in the gallery nor any links; it'd be nice to see your stuff.

Well yeah, I have several remote options but none of them work with copal shutters! The thing is, with LF you fire remotely and you get one shot, and you're done. With an rz, I can sit in the nice warm car, with hated seats, and fire remotely... Anyway, it can be done, I just don't have time.

Use plastic trays and containers? I do hope you aren't using your kitchen sink for this!

I'd definitely like some. I still have some old plates with emulsion on them and have had a ball with them. For one thing, you can make decent b&w projection slides with them, which is great for those of us who don't think powerpoint can do justice to an analogue image.... For what I have been...
