so moh is there any other way to do besides spending 160 bucks here is what nations said to me

[Michelle] it will show you in "document size"
[Michelle] in inches
[Corey] yes
[Corey] the doc size is 20x30
[Corey] 300ppi
[Michelle] you should be fine.
[Michelle] If you are unsure about your resolution in any way, you can put a note on the order when you place it with us and we will check it for you. No matter what, if we think you will not be satisfied with your prints, we will notify you and you will not be charged for the order.

DO you trust this?

Interesting, they probably think you interpoloated the picture yourself. They don't realize that you probably just raised the pixles through "image size" (is that right?)

Do you have photoshop? If you do, get a cheap plugin for it and you can do it. But Robinson says he's done it w/ his photoshop CS4....

hmmm this should be interesting hahaha!

did you do any PP to your image? If so, do this, take the RAW file, open it to a 300ppi - 16 bit TIFF file and edit that.
Don't change anything as far as sizing. Save the size of the image as is. Send it to the printer with your original size. They will change whatever needed to make it into 20x30

the file is not a raw file does that matter?

Hmm...what file is it? If its not a RAW don't worry about converting it to anything. They accept in JPEGs & TIFFs in most printing companies

If your original was 2000 x 3000 and you print at 300 dpi, then the largest you can print the image in photo quality is a 6x10 (2000 / 300 X 3000 / 300). To print larger, the printer has to enlarge each pixel which is why it looks like crap.

If you drop your dpi to 100, then you can print at 20"x30" without having to enlarge the pixels, but 100 dpi is much less than photo quality so you'll be trading off the photo quality there too.

Right......BUT they can do a better job at enlarging the pixles than him doing it at home. Or else, we wouldn't see those large poster boards on the sides of buildings or even a billboard.

The point is for him not to touch the size of the image and let the printer enlarge it. TRUST ME

I am talking about the orignial pixels. For example if you have a 500D like me, my highest resolution out of camera (if I dont crop anything) is 4752x3168 (if you multiply it, you get 15.1 MP which is what my camera is. If I want to print a 30x20, my ppi/dpi is going to be 4752/30= 158 ppi/dpi. It will still look good if you have over 100 ppi but wont be as good as 300ppi. at 158ppi my print will look good like a poster, but if you come closer you can see the pixelation a bit.

So what this all boils down to is send my files to the printer and tell them to enlarge them to the 20x30 size

and don't print at 300 dpi...print at 100dpi. A 20x30" enlargement of a 6mp image printed at 300 dpi is going to look aweful.

YESS! They will figure out and interpolate the image for you with their software and it'll come out crisp (of course if the original one is crisp :lol:
