QuoteOk, I need some help here. Maybe a dumb question but... I made all the steps for processing my dual iso photo and in the end I cannot open the final DNG file. Which version of Photoshop and ACR do I need? I have Photoshop CS3 and ACR 4.6.
Thank you all.
Try running the Dual ISO DNG through Adobe DNG Converter (FREE) and set the ACR to match what you have. I don't think you'll find anyone here actively using that old of a version of Photoshop. Beside all of the advances in photo processing in the last 5+ years.... it may be time to think about an upgrade. At least try Lightroom 5.6 it's free for 30 days...
