Just overexpose and develop as ISO 400. So basically, all your photos will be 2 stops over exposed, which on most C41 films is fine, you get more shadow detail and colours tend to fade just a bit.
Thanks, I'll try that.
Also I'll give Reala a try as well when I get the chance. I just picked up a roll or two of Portra 400. I'm curious to see how the color film develops. Only have ever shot and developed with black and white films.
