I disagree, about DPR being a good resource, particularly for Olympus images. DPR uses Adobe Camera Raw for all it's raw conversions...and worse yet, most times a Beta version of the Olympus ACR. From my experience Adobe Camera Raw is, at best, a very poor conversion tool for any .orf file, it leaves these wormy Fuji-like artifacts in almost every file. Olympus Workspace is a much better conversion, but DPR will stick with its affinity for ACR. I never recommend that anyone uses DPR for any image comparisons involving Olympus.
