Bridge Export to Hard Drive

I use the Image Processor in Bridge (CS6) to create jpegs after I process the RAW's in ACR. It opens and works thru PS. Lately I've been trying out the Export to Hard Drive in Bridge. It seems to work a little faster, doesn't open PS, with pretty much the same options. I have noticed that a few, not all, of the file sizes will be slightly different depending on which of the two methods I use. The only other difference that jumps out is using Image Processor tags them with 300 ppi where the Export doesn't which shouldn't matter. Does anyone know if these two methods are basically the same as far as results? Any advantage of using one over the other?

ppi is meanlingless unless you're printing. It is the overall pixel dimension that matters, IE 800x600 pixels. Whether image of that size is set to 72dpi, or 300dpi, it is the same resolution viewed on a computer screen. As far as results, if you are applying output sharpening with the export, they will look different.

Yep, knew that didn't matter but was the only difference I could find. Mainly I was wondering if any major difference in the rendering of the jpeg due to not opening in PS when using the Export panel in Bridge. The Export to HD seems to be extremely fast when making the low-res proofs.

I hadn't checked out the Image Processor and the Export in my "new" copy of CS5. I just ran a shot through them both, but something got screwed up by the Image Processor -- it made a much smaller copy (pixel dimensions) than I thought I "told" it to. And, the Export dialog, in which I set a Quality of 8, made a much smaller jpeg file size than I expected, at least compared to the Lightroom Export, dang, back to the drawing board!

I've played around a little between Export to Hard Drive and the Image Processor. I converted the same RAW file (2800px by 4200px) with the following results: Export Q8-842kb, Q10-1.71MB. Image Processor Q8-915kb, Q10-1.75MB. According to somebody over at the Adobe forums, this is probably due to differences in the way the metadata is written. Quality should be equal.

If you want to see speed conversions - use the Export, constrain to less than 1024 pixels, untick Render from Fullsize, and set Quality to 8.
