Re: Removable Backs on 4x5s?
Any camera with a reversible back does this easily, but what camera are you using? You should be able to insert a filmholder or Polaroid holder without disturbing the camera. On very light cameras like a Gowland it may take some finesse (like pulling the spring back with one finger and pressing the camera with the thumb), but it's still manageable.
Re: Removable Backs on 4x5s?
Any camera that has a "reversing back" (as opposed to a "revolving back") has a removable back - one changes the orientation between vertical and horizontal by taking the back off the camera and replacing it the other way. Most 4x5 cameras have reversing backs.
But normally you shouldn't have to do that just to get the holder in without messing up the focus badly. A few questions to help sort this out: What camera are you using? Have you tried using regular cut sheet film holders in the back? Is the spring back very tight? When you say getting the 545 in is never a delicate operation, what specific problems do you have when you're inserting it?
Re: Removable Backs on 4x5s?
Oops, from the other thread I see it's an Ebony SV45U. That shouldn't be causing you lots of trouble. Again, what specific problems do you have inserting the Polaroid holder?

The spring back is relatively tight, but I presume it's supposed to be if it's to maintain a light-tight seal. I am able to insert holders, but the Polaroid 545 being that much clunkier than the QL holder takes more force - particularly at the half way point of inserting or removing.
I've always loaded film w/ holder with the back on the camera. Perhaps it would be better to just remove the back, then load the film holder and reattach the back to the camera.
Re: Removable Backs on 4x5s?
I only use polaroid to see what the compositions looks like. I NEVER depend on it to check for critical focus. The sloppy fit of the film in the holder is the cause of the shots to be off that little bit that you describe. S%*# can the training wheels and the keepers will grow. Shoot chrome, and get better results at a cheaper price. I say chrome as it will not be subjected to all the variables ( options ) you will have when doing B&W. Exposure tolerance is tighter in chrome, which will pay dividends when you go to B&W later if you choose. Your going to have to do it sooner or later. Get a notebook and keep records of each exposure as a reference when evaluating your shots. When doing film test I put in my Macbeth test card along with exposure info that I put on index cards with a magic marker. I have a full set with a shutter speeds, f-stops to the 1/4, +3 to -3 over and under cards and EV#s. Include the applicable cards and you have metadata in the shot itself.

I forgot to add that I also insert a card for the film and speed brackets are based on.
Re: Removable Backs on 4x5s?
Check with Richard Ritter. He makes a bail that attaches to your back that actually moves the back out very smoothly and effortlessly for film holders or whatever needs to be inserted.

A number of 4x5 cameras (including some of the Calumet and Toyo models) have backs that feature a "bail" that will gently lift the focusing frame to allow the film holder to be inserted with no struggle, which I think would meet your objective.
Re: Removable Backs on 4x5s?
See Alan's comment above and have a bail made. Also, you aren't alone. I had a partivcipant at a workshop several weeks ago who expressed similar concerns with the same camera .... I think he is having Richard make him a bail.
