    Re: How Have You Made a Plastic GG

    I've used 'anti-glare' styrene, which has a frosted side to minimize reflections for a frame in bad lighting.
    Just cut down to the right size, clipped the corners, and marked my grids.
    Most likely...

    Re: My hyper-confused self and the f-stop

    The fact that the math works out is why I'm asking all these questions. If the math didn't work out then I'd just throw my hands up, meter something, and hope my negatives come out.

    Re: My hyper-confused self and the f-stop

    Isn't that based on a 'correct' metering system though, i.e. a system looking to put faces on zone VI, deepest shadow detail on zone III, etc? Something looking for avg. zone V would say a black dog...

    Re: My hyper-confused self and the f-stop

    Oh sorry, I didn't phrase that very clearly. What I meant by lenses giving an exposure was a lens passing enough light to properly expose a film to a given density.

    slightly different question (I think different?):

    Re: explain like I'm 5......... 90mm lenses

    Wait now I'm further confused lol.

    f/8 for any two different focal lengths is the same light input total. Isn't it kinda like slow, wide river or fast, narrow river?
    A 3000000mm f/8 is picking up...

    Re: explain like I'm 5......... 90mm lenses

    Wait but doesn't this not work? f/8 on a 90mm lens is a lesser transmittance than a a f/8 150mm, because the 150mm lens is a narrower FOV.
    Both transmit the same total amount of light but with a...

    Oh good to know! How much have you found it's non-folding design to be a nuisance while backpacking? Also, that picture under the wharf is great!

    It is!! Have you been? If so, what area were you in and did you take any photos?

    explain like I'm 5......... 90mm lenses

    Hey there,

    I'm new to the LF game and I have a few questions about 90mm lenses.
    As far as I can tell there are lenses like the Fujinon f/8 which are huge, and lenses like the Schneider f/6.8...

  23. Re: Me, my inexperienced butt, and the backcountry

    The Crown graphic is nearly 5 times as heavy, and doesn't offer as many movements. If I need to settle for a graphic I will but I think the Intrepid is a better option.

    The other reason I'd like...

    Re: Lens questions from a new 4x5 shooter

    Well with an accurate shutter 1/200 should be good enough, but if shutters aren't accurate I might need one 'rated' to 1/400 or so to actually get a 1/200 or so exposure, right? I guess what I'm...
