They all want pixels/inch...so if the say they want 300, then for a 8 x 10, give them 2400 x 3000. If you give them smaller, they will resample up.

The "shaprening for print will look overshaprned on a screen".... look at it at "Print Size", assuming you've set the preferences properly.

Right. All the Fuji and Noritsu machines need to be fed 300 ppi. If you resample down to 240 they will bring it up to 300, so you get double resampling. You lose detail and then you make the no-detail bigger.

I leave my default output on LR at 240 and haven't had any issues with WHCC on that front. I would try doing some output sharpening for print, as Tony mentioned earlier and see how your results come out.

you can change the output in LR? can you pls explain where?

Thanks. I just did that and exported it as a PSD. 300ppi

Problem though.

Once I do my final edits in photoshop cs3, it wont allow me to save it as a jpg. JPG. isn't an option... ! ? !

Do you have Layers ?

if so, flatten the image before saving.

no, no layers, all flattened. thats why i'm finding it so odd.

do you have CS3 or above? i think CS3 is a little limited with its communication with Lightroom.

i was told by WHCC that I would need CS4 or above...

It is in all likelihood in the 16 bit mode -- go to Image and Convert Mode to 8 bits per channel and you will be able to get jpeg on the Save As drop down list. Just make sure your jpeg Quality setting is right if you are preparing this for print.

Bingo! Thanks man!

Should I worry that 8 bits is lower res/quality vs. 16 ?

No. You have to save as 8 bit if you send it to a photo-lab. The conversion algorithm is very good. You won`t see much difference if you see it at all.

Yeah, like above, 8 bits is the way to go when you are ready for a final output, in fact as you've seen you have to use 8 bits to convert to a jpeg.

Your Raw processor is setting things to 16 bits -- you can actually change that to 8 bits if you want, but many of us keep a "project" in 16 bits to get the maximum latitude in processing. It gives a similar advantage to what a Raw file gives -- more bit depth means more data that can be "massaged" without creating any messy artifacts.

But, for many applications and some Photoshop plug-ins, 16 bits won't work, so it's not uncommon to have to convert over earlier on. It forces you to make a workflow decision sooner rather than later. But some things will do fine with 8 bit files. And Elements barely can do anything before you convert.
