use a large enough sheet of paper that you can wrap it around the edges of the panel and tape or staple it to the back, and add a layer of chemically neutral plastic or something between the paper...
work on your reading comprehension, because you didn't address my points directly or disagree with anything i said.
you're not telling me anything i haven't known for decades, or disagreeing with anything i actually said, so why did you bother with that long-winded, condescending comment?
you don't.

watt-seconds isn't any more of a marketing ploy than the wattage listed on an incandescent bulb. it's just a measure of power input to give you a rough idea of the flash's output. guide numbers are...
wet plate grain structure is outside my area of expertise.
the narrower the spectrum the less chromatic aberration you get. uv has higher potential resolution than longer wavelengths. wet plate has extremely fine grain and high contrast.
and the contacts behind the bipin connector, and the switch that breaks the circuit when the shutter release isn't being pressed, under the cover plate on the side.
they're reliable if all the contacts are clean.
adding this to my list or reasons to like my speed graphic. :p
gel the backlight to correct the orange cast. it's a lot easier to do colour corrections in software if you start out with all three channels properly exposed and you can correct the colour cast more...
if you want your trays and whatever else level, you could just add a little level strip around the sides of the sink to support wire mesh shelving or those plastic grids they put on ceiling light...

lightroom only skips previously imported files, not files that are identical to each other within an import.
absolute bare minimum, your image circle needs to be wider than the diagonal of the image on the film (152mm for 4x5). the closer it is to that minimum the worse your image quality and vignetting...
tincture works fine as long as the plate is warm enough to prevent condensation. a piece of paper towel will help the tincture evaporate better than just using a drop. no idea if it'll be precise...
if you ever do want to try it, your camera will work just fine as an enlarger with some pretty basic addons.
corroded magnesium. just scrub it off with a wet toothbrush. a bit of carnauba car wax will help prevent any future corrosion.
green x-ray film is orthochromatic, so you want a cyan filter.
blue or green? don't expect anyone to tell you if you overexposed or overdeveloped when none of us can see the negative.
you could always toss a tea bag in your rinse water.
not porn, anything they don't consider "Acceptable to a global, public audience", so even stuff you'd find in national geographic.
if your advice to someone asking about large format photography is "shoot medium format", you might be on the wrong site.
totally different back, so that thread's full of advice that wouldn't work.
keep the focus rails all the way back and locked then adjust your front standard while focusing on the moon or something else really far away.
it's not about how far the light is traveling so much as the geometry involved. the focal length and f-stops marked on a lens are only accurate when focused at infinity. the closer you focus the...
don't forget you'll also be gaining maybe half a stop or so of light due to the change in f-stop with the +2 diopter. might be easiest just to set up your shot, focus, stop down the lens and measure...
right, so you can't divide bellows length by focal length without knowing the focal length and you can't get a metered time without knowing the f-stop. a positive diopter shortens the focal length...
how do you calculate bellows extension without knowing the focal length? how do you calculate exposure with or without correcting for bellows extension without knowing the f-stop?
diopters change the focal length and entrance pupil diameter, the two measurements that determine the f-stop. you're not calculating anything without knowing those measurements.
never seen a prime lens with an aperture that shifted position relative to the lens elements when focusing, so i doubt that's the issue. most likely the lens elements just aren't optimized for...
easy enough to measure the depth of your film and the gg to see if they match.
graflex back, not graflok. too old to have a fresnel.
diopters will change your focal length and f-stops. you'll need to measure the new focal length at infinity and entrance pupil diameter with both diopters.
the lens part of the fresnel is in direct contact with the gg and shouldn't cause any significant shift in the focal plane, which just leaves the potential shift caused by 1/16" of acrylic, which...
depends on the holder. calumets are notorious for it.
it was designed for a fresnel under the gg with the grooves facing back so they don't get scratched by film holders or when the back is removed. i'm tired of repeating myself. i don't care how you...
not on a crown/speed graphic. grooves against gg so the fresnel doesn't shift the focal plane or soften the image and the grooves are protected from scratches.
