Size for cropping for printing - DPChallenge Forums

Hi....took some pics at the local go cart meeting, promised them a copy of the pics but would like to edit the shots (crop the cr#p). Once edited will put them onto a CD which they can copy/print...whatever. What size should the images be? Do I need to make them similar sizing to dpc prints proportions? Am not sure if they'll be printing them themselves or going into one of the photoshops. Only printing of my shots I normally do is on the printer at work so size doesn't really matter.

thanks
sue

4 x 6 (1200 x 1800)

8 x 10 (2400 x 3000)

Chances are they will want 4x6's. If they want enlargements, most likely 8x10's.

Watch your DPI settings... 1200 x 1800 is an 8x12 at 150DPI and a 4x6 at 300 DPI. For most things 150DPI should be fine though.

Just give them the maximum resolution your camera provides. Worry about DPI requirements when you know the print device. 300dpi is just a number out of a hat. 150dpi is not fine for most things.

am having problems getting 1800x1200. Have got ps7. What do I enter where to get the right size. The pics need rotating slightly to remove camera angling so need to crop. With the crop tool is there somewhere you can see the size as you crop???? Heeeeeeelp!!

am I better off putting 150 or 300 in the ?dpi box next to the size?

I would use 300dpi.

Is there a way to do this in PS Elements?

This works in PS Elements too. Click on the Crop tool and enter the width and height in the boxes on the Options toolbar (choose Window->Options if it doesn't appear). It's a good idea to include the units (e.g., "6 in"). The crop will then be constrained to the specified proportions. Click the Clear button to remove the value and return to unconstrained cropping.

I usually leave the Resolution box blank. Then crop won't resample (unless you rotate at the same time) and just keep the camera DPI. I prefer to resample explicitly when I decide what the output device and size will be. But for quick fixes at small sizes, putting your target resolution can save that later step.

If you enter specific size dimensions (e.g. 6" x 4") and leave the resolution box blank you DO resample the image, but it does not change the resolution setting (ppi), unless you happen to select just the right number of pixels.

As an example, if I have an image 288 pixels square, it is 4" x 4" @ 72ppi.

If I set the crop box to 6" x 4" and leave the resolution box blank, I should end up with an image 6" x 4" @ 72pp or 432 x 288 pixels (resampled up 50%).

If I added the resolution setting of 300ppi to the crop dialog, then I'd end up with 1800 x 1200 pixels (major resampling).

If you leave out the specific measurement units (just set the crop tool to 6 x 4), THEN you end up cropping to a specific aspect ratio, but without resampling. Then you can resize the image and change the resolution setting as necessary in the Image Size dialog.

I entered 300 in that little box.......does that mean they could have problems printing the pics as 6x4's

The only numbers which matter for printing (at DPC Prints or other photo imager) is the total number of pixels, and the ratio of their arrangement. You could submit the same image at any of the following settings:

6" x 4" @ 300 ppi (= 1800 x 1200 pixels)

or

12" x 8" @ 150 ppi (= 1800 x 1200 pixels)

or

24" x 16" @ 75 ppi (= 1800 x 1200 pixels)

or

25" x 16.6667" @ 72 ppi (= 1800 x 1200 pixels)

... it makes no difference to the printer.

However, if you do not have at least 150 ppi at a given print size, the image will not be approved for public sale, although you can order prints for yourself at any size.
