another cropping/dpi question. Reply

    I want to make larger prints. Usually I crop to 4x6 and then set the dpi to 250. How do i go about doing larger prints? if I look at a SOOC picture in PS it says it 53.778 x 36 and 72 dpi. lets say it's perfect as is, I dont want to crop it all. If I look at image size in PS, and have resample UNCHECKED, and change the size to 16x24, my resolution changes to 162 dpi, my pixels stay the same, 28.8M.
    Which I thought was desireable. But I keep hearing to aim for 300 dpi. So how do I crop to get 300 dpi and an image sized 16x24?

    Hi,

    Just create a new image in photoshop, something large like 30" by 30" at 300dpi

    Open your image and drag it into your 30x30.

    now just crop to what you want and it'll be still at 300dpi.

    READ THIS! - http://www.rideau-info.com/genealogy/digital/dpi.html

    I spent ages tearing my hair out - wondering how to get my photos to 300dpi - You DON'T need to! Leave your photos as large as possible to get the BEST print quality. Virtually no cameras store photos in 300dpi - most store at 72dpi.
    THe less you mess around with the photo the better - unless you REALLY know what you are doing. They shouldn't be talking dpi (it means nothing! except to print shop people) - if you read the article it SHOULD all make a lot more sense.
    I notice now on one of the pages in Artscow they tell you the minimum pixel sizes you should be aiming for. My example - a 6" photo for BEST quality needs 6x300=1800pixels by 8" 8x300=2400pixels - so if your photo is above this eg. 1800x2400 you'll have a perfect 6x8 print etc. etc. Anything above that quality is a bonus - don't reduce it - they can work with it!

    My question is about the format specifications ArtsCow requires to get the best quality print possible. I assume the file to be submitted with RGB color mode and although I set it to 150 or 300 DPI, I am unclear if that makes a difference with JPGs - the number of pixels is all that matters. Is my assumption correct?

    I have created these exports and am unsure which one to submit:
    - JPEG With .25" bleed: 1MB file size, 3675 x 5472 px (150 DPI)
    - JPEG Without bleed: 1MB file size, 3600 x 5400 px (150 DPI)
    - JPEG With .25" bleed (high-resolution): 11MB 7354 x 10950 px (300 DPI) - too large probably?
    - PNG With .25" bleed (high-resolution): 2MB 7354 x 10950 px (300 DPI)
