I've see some spectacular HDR metaphors on Flickr and would love to hold a run at getting these mode of colours / shadows into my descriptions but I'm reluctant to try if I'm going to struggle to produce trait results starting near JPEGs. Do I hold to start next to a RAW sign? Is it possible to convert a big resolution JPEG into a RAW in rank to HDR render it within photoshop CS3?
Answers: If it is a big resolution JPEG resembling you state, afterwards you should not own any trouble using HDR in CS3. You can still acquire power results from JPEGs.
You can convert a JPEG into a RAW directory. However, I do not recommend it. Then you enjoy a RAW folder explicitly missing some essential facts. Just use the straight JPEG within the HDR tool.
