LRv2.3-Export-Action-Droplet Question

[Souwalker]

Hi

I was reading Kelby's LR1 book and under the Export section, I was following instructions on how to Export and use a Droplet as part of the Export.

In the instrcutions, I had to create a PS action called Luminosity sharpening. I had no problems with this. The instruction told me, as part of the final stages of the recording of the action, to then do a Cntrl S to Save and Ctrl W to Exit. When I do a Cntrl S to Save in PS (CS4), get a Save As dialog box to give a name, I do this, select OK and PS displays the Save as Jpg box where I need to select the quality of the jpg.

Here's where I am confused. If I export from LR2.3, there is already a section to export in jpg with the quality setting. I select, say 8'. As part of the export, I also run that droplet (created from that action on CS4). Will CS4 then save the file again in jpg with the quality setting I had to set when I created the action in CS4 above? Double saving? Or if I export from LR and run that drop as part of the export, PS does nothing 'but' run the action? Which software has preference?

Also, I know I can preview a preset from a small display box at the top. If I applied any presets, will I be able to undo that preset only and leave anything I did to the file prior to running th preset untouched? If so, how?

Thanks
Pat

I'm not an authority on this, but I expect that, yes you'll see double compression. I believe you'd want to export from Lr to the droplet with a lossless format, such as TIF, and do the JPG compression on the final save from PS.

Also, I know I can preview a preset from a small display box at the top. If I applied any presets, will I be able to undo that preset only and leave anything I did to the file prior to running th preset untouched? If so, how?

[COLOR=#''''ff]Yes, you can undo it, either by a menu 'Undo', or ctrl/cmd-Z. Or, you could select the history step previous to the preset. For absolute certainty, you could create a Snapshot or Virtual Copy, prior to trying the preset.[/COLOR]

Brad has it right. LR exports a file, then passes it to the droplet. In the end it will be double-compressed. If you have LR create a TIFF and have the droplet save it as a JPEG, you won't suffer that quality loss.

Alternately, use your droplet as an external editor rather than as an export action.

Or save to quality 1'' in LR and then compress more in the droplet if you want to. It won't be a real-world visible loss unless you run it hundreds of times.
