I shot a short roll of Kodak 500T (16mm). Upon finishing I noticed, much to my dismay, that the ISO on my light meter was set to 50. So, the fast film's exposure index is rated at 500T and I overexposed by how many stops? Can either push or pull (pull, right?) processing save this spool? The negative is probably pretty dense too, right? I saw a latitude test where film was overexposed by 5+ stops and it looked nice. Hoping there's a way to remedy this problem.
