Cross processing 4x5 E-6 film in BW chemicals

I have just started experimenting with pinhole photography using 4x5

Plus X-Pan. However I also have some 4x5 slide film - Ektachrome 64

both daylight and tungsten. I know E-6 film can be processed in C-41

for funky effects but I am wondering what I can expect if I process

it in Black and White chemicals (I have D-76 and Microphen). I am

expecting some image to appear, but really have no clue beyond that.

Will it mess up my chemicals. The developer is one shot anyway, but

will it mess up the stop bath and fixer. I am asking because I don't

want to ruin an important roll of 35mm later by using those

chemicals on it. Any examples of such cross processing or general

advice about times etc will be much appreciated.

I know I could get slides but they are too costly for me for oatmeal

container photography right now.

Thanks,

No, it won't mess up your chemicals. But the yellow colloidal silver mask will still be there, which is normally bleached out with all the other silver in E-6 processing. This will make for a dense base.

In some ways, the best way to process any color film as B&W is to do B&W reversal processing. That will bleach out the colloidal silver yellow filter.

I've doen this before by accident, shot a chrome and B&W neg of the same shot, and mixed up the film holders. What you'll get is a very dark, nearly opaque piece of film with an image that shows up when held up to a fairly bright light source. It's probably not going to be anything you'd want to do.

Ah now i know what Koduck did to my last rolls of E-6 film before i got my D-70. They said it was my falt and that it was unexposed even thou you could see stuff on in bright light.

Steve;

What Peter didn't mention is that the film is dark and YELLOW. This is due to the retention of the yellow filter layer in the film.

It would be a rare event in any case to have Kodak mess up your film. They generally don't do any B&W processing at Kodak or Kodak affiliated labs. Most B&W is done locally by smaller companies.

Your slides are either underexposed or the process was out of control. Poor first development or poor bleaching will lead to results similar to what you see. If you suspect that the process was at fault in any way, you have a legitimate complaint to make against your photo lab.
