    Default Setting DPI and Image Size

    Hi everyone
    I entered one of my shots in the junior section of ANZANG, and it's been selected for the second round of judging, but I'm having trouble setting it to the specifications

    I've been told to send in a CD of the selected image as a TIFF file. It needs to be at 300dpi, A3 size, approx 60MB, in RGB colour space with working space embedded or tagged (ideally AdobeRGB 1998)

    Unfortunately, I've now realised that I cannot set the photo to 300ppi AND have it A3 at the same time (only A4)... does anyone have a way to do this, or is my camera set wrong (eg; do I have to shoot in RAW to do that)? Either way - I'm pretty sure it'll end up losing a lot of resolution

    Congrats on making the 2nd round Josh.

    I have very little free time ATM to describe what you need to do.

    Do a google search on upsizing images and try one of those methods depending on what image editing software you have.

    Let us know how you go. I will be back online in a day or so and if you still have problems I will try and walk you through it.
    Cheers,
    Geoff

    I had already done a google search, and the problem was I can't find a way to change it to A3 while keeping the ppi at 300... I'm not even sure if it's possible

    EDIT: Don't worry - I found it - I just have to untick the resample image box
    For the future, is it possible to set a camera so it shoots at a higher ppi?

    Congrats Josh!
    Sounds like you have found the answer already so apologies for not seeing this earlier. To get it to the size they want you do indeed need to interpolate the image. Basically that means adding information that wasn't there in the first place. The "damage" done to get it to that size will depend on the size of the original. You can't alter the dpi that the camera shoots at but this won't make any difference anyway. It's the overall pixel dimensions which. You also can't change while shooting to be any bigger than the full size raw file. You will be surprised what you can get from photoshop in terms of quality of interpolation anyway. I have a 16x24 inch print taken with an old 10D on m wall that made it into the first ANZANG and it came up really well at that same size.

    PS sorry hope I diddnt confuse you with dpi instead of ppi! Dots per inch is what I am used to from printing quality etc. Can't get used to Pixels per inch
    Cheers, Dave

    Thanks David I had previously spent a while trying to figure out to difference between DPI and PPI, only to find they were the same

    I only entered two shots in the junior so it was only $15

    All goes to good causes IMO Akos, as well as opening peoples eyes to the awesome natural wonders that surround them.

    I am sure all monies go to great things Paul, but I cannot afford that sort of crazy entry fee. The amount above alone would barely feed my animals for a week (let alone the rescued wildlife in care). You know what I rather choose! It's priorities I guess and I can certainly promote the cause without paying for the privilege.
