If you want to print a photo, and you shot RAW. Then the steps would be:

1) Use RAW conversion software to do all your editing etc.
2) if you have photoshop, transfer the raw into photoshop and do whatever you need to.
3) Your Resolution is what is important in printing. So when you go to print it, you want a good resolution, like anything over 200dpi or even 300dpi.
4) from there, a jpeg would be fine to print.

This Tutorial can help too.

Ok read the tutorial still confused! I should clarify I have taken some photos of a friends daughter. I would like to put them on a disc for them so they can do whatever prints they want....so I dont know what size they will get printed.

So i know how to resize for dpc so when I normally go to the width and height in the image size box I choose the highest number and replace it with 640. What would be a good size for a images on a disc?
I gather from the tutorial I should put the resolution at 300.

Then I go to save for web and optimize the file size to 150 coz thats what DPC wants. Whats a good size for images on a disc?

Sorry for all the questions :)

If your putting it onto a CD, then it's better to leave the size at the normal out of camera size. And since you did shoot RAW, right? The resolution should be fine. Most likely 200+

So check the metadata, and see what the resolution is, and if it's 200+, then your fine.

So saving as Jpeg should work well. Don't save for web though.

Don't change the image size, just do a straight save/saveas as a JPG. The DPI won't matter at any labs.

Make sure the image mode is set to RGB (ALT I+M+R to convert before Save As jpg)

yip it is RGB grr I'm obviously missing something or doing something wrong

You said you can do it via Save for Web? That's fine - just set the quality to max.

Ok which takes me back to what is a good size for width and height?

12/10/2007 02:37:23 AM · #11

Before you save for web - select the crop tool and in the options on the toolbar for the crop tool, set the width and height based on the print size you want and leave the resolution blank. Then crop. It will maintain whatever DPI it is. Then just save for web as highest quality jpg

I net you are still in 16-bit mode and/or "un flattened" hence the no JPG option.

Yeah - if there are layers, you need to Save As...

Thanks Leeroy that was it the 16 bit mode so I changed to 8 bit and then I had a jpg option under save as :)

Dont really know about bits would never have figured out that myself. Thanks to Ken too for always trying to help a dunce like me!

You're not a dunce - just a 16 bit girl living in an 8 bit world. :D

LOl Ken you are a very clever funny guy :)

You know I know of quite a few people who dont use raw because they could'nt convert to jpeg. I used to think what was their problem!!! That coz I could only do it for the web!!! I think the bit thing is what is tripping most people up so make sure you spread the word ;)

What do you submit for printing, bitmaps?

Of course you CAN use the "save for web" option to have images printed, but you won't get the best possible results. Besides that there is a size limit for saving for web.

Creating jpegs for prints by saving for web is just as stupid as converting the imges to CMYK just to have the printer convert them back.

Have you ever noticed the difference in file sizes between "Save as..." jpegs and "Save for web" jpegs - How could it be possible without a loss in quality?

Save As maintains EXIF data, that's the only difference. Oh, and the quality knob goes up to 12 instead of 10. However max settings 10 and 12 both equate to the same level of compression in the final image.

If there is a limit on what size file Save For Web can deal with, I have never hit it. Ignore the stupid memory warning and let it do its job.

The problem with "save for web" as a print file is that it defaults to less-than-optimum file sizes. You need to know what you are doing to tweak "save for web" to best image quality.

Since "save for web" is specifically designed so that you can balance loss of quality vs file size, and since when printing you always want, as a rule, highest quality regardless of file size, it makes more sense to use "save as" in the first place, since the quality slider is right up front and the whole process is more intuitive.
