8MP image
8.16 x 10.88 300 ppi

If i was to crop this image lets say to 11x14 with 300 ppi what type of resampling does PS3 use when cropping this image if it uses bicubic smooth resampling i know the image will be alright. Just need to know what it uses to resample and if it just uses bicubic will that be fin for an 11x14 print? Nothing any bigger

thank you

Photoshop CS3 uses Bicubic Sharper to downsample, and Bicubic Smoother to upsample.

You've got your terminology off, though. You don't "crop" to make something bigger. When you crop, you take a part of the image and remove the surrounding portions.

An 8.2MP image at full size is 3456x2304. At 300 DPI that works out to 11.52" x 7.68".

i totally thought you were talking about Playstation 3!

I use this page to figure all that out //www.dpcprints.com/help.php?faq_id=61

Edit (again)

I use Bi-cubic scaling in the GIMP to print 19x13 on a Canon 9200 and it works quite nicely...

So does that mean i need to enlarge my image using bicubic smoother, then crop it down to get the results i need?

If you are going to put prints on DPC Prints your Resolution and DPI (150/300) must match the chart in the link.

I crop to the Aspect ratio first for example 11x14 = 1.27:1 and then scale to the resolution and dpi 3300x4200 for 300dpi prints or 1650x2100 for 150dpi prints.

I have had 150dpi 16x24s printed by DPC Prints and they came out fantastic.

its not going through dpcprints this is just to print it out and have good image quality? also im using PPI not DPI? if that matters at all.

Typically "PS3" is PlayStation 3.

Typically it is Photoshop CS3 or CS2.

You kind of had me confused there...haha.

Haven't heard PPI in a while so I that part kind of screwed me up...

Anyways, in a nut shell PPI (monitor terms) pixels has spaces between them DPI does not (its the other way around). 300 PPI divided x2 (for spaces between the dots) and you have 150dpi which is a standard for acceptable quality prints.

As to the sample are those 100% crops? Don't judge print quality by looking at something at 100%, you will see stuff that scares the daylights out of ya. I find viewing a shot at around 33% to 37% on the monitor is pretty close to what the print will look like.

Edit: I really screwed that up

33% doesn't render super sharply. View tham at 25% and 50% to see the sharpness accurately or you'll scare yourself again!

in that case maybe i shouldnt look at this picture of me at all because if 37% will scare me im totally not wanting to see 25% lol thats for all the help guys i look forward to hearing more commments on this subject
