Expired film

Although it seems counterintuitive, I've always found that "Pro" labeled films were less robust in terms of abuse or exposure latitude. Shipped and stored refrigerated with emulsion batches kept in bricks, a pro with controlled lighting and color balance can get consistent results. The entry level priced consumer grade films, like Kodak Gold, Ultra Max, or the non-Superia Fujfiilm Fujicolor are designed for a lot more tolerance of heat and age and exposure errors.

As I understand it, pro films - bought in some quantity from the same batch run, ensures that color/contrast will be the same. But I don't know it myself if this is true or not.

Regarding exposure errors, I have tested most all Kodak and Fuji color negatives and they all have exceptionally wide exposure latitude and more so on the over side. Kodak Portra 400 is a great example of this.

Hi all, I'm after some advice for exposing and developing expired film.

With my recent Hasselblad find I've picked up 2x Reala100, 2x Velvia100f and 1 roll of NPH 400. Unfortunately all of it expired around 05/06 and I don't believe it's been refrigerated...

Thoughts?

Thanks, Nick

Well, I would overexpose the Realas by 1-2 stops, overexpose and cross-process the velvias and try NPH at box speed to see what happens

Why would you cross proceed the Velvia?

Since the films are long expired and kept in unknown conditions the color balance is probably already off, so I can't expect any color fidelity. I love slide films and usually shy away from "ruining" them by cross-processing, but in this case they are halfway there anyway.

I'd vote for cross processing C41
