Accidentally super lowered ISO of a slide film, very sad, can it be pushed ?

Well, can't he jusr

Can't he just develop for a 3 stop push? It's not impossible or out of this world... There was even a chrome film from Fuji that was ISO 100 and designed to be pushed up to 1000: Fuji MS100/1000...

Having grainy "pushed" images is better than having no image...

I have purposely pushed slide film 2 stops with great results. Never tried 3 but I think you can do this with good results judging from my past results.

I've personally shot Provia 100F at EI 320 (1/3 stop slower than 400) and had it pushed 2 stops. It came out pretty well. Definitely a contrast boost, and better suited to indoors with flash than outside on a bright sunny day, but there was definitely something there.

If the OP or a lab was willing to push 3 stops, there would definitely be *something* there. Pushing slide works far better than pulling slide film, IMHO. In my experience, highlights still get lost when pulling slide film.

Well it will be really nice if op sees this and replies back to share what eventually happened as he has not posted.
Remember this is very old thread.

Since he hasn't logged on since Aug 2014 it's not likely.

Rogers that!
