Incorrect ASA setting


I bought a box of 4 rolls of Fujicolor Superia X-TRA 400 ASA. Unfortunately I didn't notice they threw in a bonus roll that was 800 ASA.

So I shot a roll of 800 ASA film with my Nikon FE set at 400 ASA.

Can anyone give me an idea if there is anything I can ask the developing lab to do to compensate? Do I need to go to a special lab? Also, can they compensate enough for me to do the rest in photoshop?

Obviously a novice,
D Dean

  I used to work in a photo lab... maybe you can ask them to develop your roll at a certain speed. I am not sure if that will work for color film or not. The other option is, maybe they can push it a few stops. I am not sure if that will help either though. I think if you tell them your dilema, they will find a way to help you. Just make sure you bring it to a GOOD photo lab (people that accually know what they are doing) and not some place like Walmart. You can ask them if they do their own color adjusting. They can probably help you the best.

  I think it'll be just fine. Most all color print films developed in C-41 process show little if any effect from push/pull development processing. Most color print film, especially ISO 400-800 have extremely wide exposure latitude, giving good results with exposures from -2 stops to +3 stops from optimal. You effectively gave the roll of 800 +1 stop of exposure compensation. I'd just have it developed normally.

  Dear DD:
John's right: One stop of overexposure is not enough to present serious difficulties to the lab when it comes to printing a very decent photo. If anything the exposure error was in the right direction. You'd rather overexpose color negative film slightly than underexpose it.

  This one's almost too easy. Simply ask the lab to process this roll at ISO 400. I shift the ISO of my 200 speed film regularly and ask the lab to process accordingly. And it's just a basic lab, nothing fancy.
