help needed ...
finally, after 3 months, i have mated a 7x11 back to my existing 11x14 camera
but i have run into problems and was wondering if someone could help me...
first of all, i have a century 8A camera and i am using the reducing back
( sans 8x10 back+glass ) as my base for the 7x11 back i have.
it didn't really fit right, because the protruding light baffle
( bit of wood that extends and makes a good seal ) is not the same size,
it is a little bigger than the 8x10, and the clip/hardware isn't lined up right
either so i figured i needed to do something drastic.
i grabbed the black acid free masking tape ,
removed the clip/eyelet hardware
and ran the tape around the back and the reducing back.
i fit it on the camera and it seems solid.
i then took it off again ( from the camera, not the reducer )
and removed the ground glass. it had about 50-100 years of grime on it.
i used a soft paper towel and warm water and cleaned it and ... big difference.
i tried to make notice how it fit into the back, shiny side towards me,
ground part to the lens like usual. i put the glass back in, and mounted
it on the camera, and it seemed OK until i pointed it out the window to
see how bright it was. it took a while to get used to glass
( i have been using waxed paper for about a year and 1/2 ) ..
and i know what was giving me trouble.
the glass must be put in backwards or upside down,
the image on it isn't right. its not dim, but bright, and it isn't upside down and backwards.
if i had known that if i put groundglass in backwards it would be like a
slr i would have done it a long time ago.
maybe it is the aspect ratio ... 7x11 is supposed to be close to the golden mean ... is this what they mean ?
when i make my prints will they be upside down and backwards too ?
has anyone else had this "trouble" ?
thanks in advance for help!

im empty, good luck
i don't get it. the 8a is a studio camera---did it come with a reflex viewer? if not then the lens should project an upside down and backward image on the ground side of the ground glass (or wax paper) no matter which side is facing the lens (of course it wouldn't register on film correctly if the ground side was facing you.) what kind of lens do you have aboard her??
Something is missing in the description. I would have to ask if there is a mirror or some other piece of glass (lens) in between the lens and the ground glass?
The camera's fine. Your brain's just changed, so now you see everything upside down and backward except for the groundglass. Happens to all of us.
I am concerned that the acid free, black masking tape may be a source of the probelms. What happened to the acid? Maybe, you dropped it?
Then again, it might be something simple...liek the reducing back not being oriented corectly in the other thingy.
Let's check the obvious things too...the camera is right side up - right? And the window....It isn't flipped around some how...has it? Happened to a neighbor. He was too cheap to have his windows replaced by a professional so, he went out to Home Depot, bought himself some replacement windows and after five consecutive weekends...he had all the windows installed but, the house was completely up-side-down!
Say, where'd you find that acide free black masking tape anyways?

i got the tape at jerry's artarama
it's good stuff!
are you serious or just effin with us. cuz without a mirror all images will be upside down and backwards on gg its fairly basic optics. even the images your eyes take in are upside down and backwards your brain just adjust them and yes the image will be upside down on the film it always is backwards no because the image is "burned" on to the front of the film (the other side of the ground glass if you want to think of it that way) even in an SLr point and shoot or any other camera the image will be upside down in reference to the cameras right side up but it doesnt matter because you can put the neg or slide in any position you want after its developed.
not tryin to break your "balls" here but this is a prety basic concept

its gotta be the acid free tape!
i know there isn't a mirror in the camera . ... and my fingers did tingle
when i put the tape on ...
John, ya knucklehead. You've put the lens in upside down and it's making the pictures right side up. You need to flip that lens 180 degrees. Happens to all of us once in a while.
i turned the lens upside down and it didn't help.
i knew i should have had ownes corning or sears refinish the place ...
i looked again, and it seems like the the window
opens from the top down, instead of the bottom up.
maybe that's my problem?
ps. i ate some of the tape this afternoon, nothing happened.
