LR: best jpg files for quality lab photo develop

Hi,

I don't have a high photo quality ink jet printer and prefer sending my selected photos (as sRGB/High quality jpg files) to a quality photo lab.

My questions while using Lightroom 3.2:

1. How do I create my jpg files, do I export these (from Develop module) as jpegs (what settings), or in the print module (print to jpg)?

2. What output sharpening shell I select (LR offers output sharpening only for local printer. Why!?): Standard/High, glossy/non-glossy
3. For high quality lab work, what dpi settings shall I choose?

Thanks

Export (from Develop or Library)
settings: sRGB (as suggested), high resolution.

I'm no expert here, but I'd try (!) standard glossy

I never bother dpi. The resolution (image dimensions in pixels) do count, the company will know output dimensions, any printer/software will do the math.

All in my humble opionion of course!

If I seem to talk nonsense or you can't understand me, it's probably my English

I do it this way:

I produce a jpg via the print module to the desired dimensions including borders and "standard" output sharpening; for my purposes (i.e., proof prints on a Fuji Frontier machine) I use the Frontier's native dpi (300) and the appropriate color space (e.g. the Costco ICC profile available from http://www.drycreekphoto.com and tell Costco not to do automatic color correction. For Chromira prints I also use 300 dpi (although the Chromira should be able to interpolate on the fly) and Adobe RGB.

Thanks all,

As the former poster didn't agree what module to use, I'd be happy to get some more recommendations.

I generally export from the development or the library as max quality jpg
Sometimes I will resize in LR. . . other times in Genuine Fractals
I dont do any additional sharpening on export if already sharpened in dev mod

fuji frontier prints at 300 dpi with a srgb profile. but the dpi isnt going to matter that much unless your planing to get enlargements. do call the place and tell them to not make corrections to the photos. also ask if they can turn off the auto correction or if they use it.. some places do some dont.. if you send the files out in Adobe RGB and the auto correction is on they will turn out bluish kinda like cross-processed tungsten e6. send some test prints out first and see how they turn out.. that is the best way to know for shur.. find a lab you like and that will work with you. talk to the printers and see if they know what they are doing.. one reason to go to a full time mini lab and not walmart or something..

Thanks for all your tips and insight!
