Tips and Tricks: Photoshop


Don't trash that shot from a distance YET

Today's cameras have greater resolution than ever and can be a God-send in salvaging some pictures. First, let's define print size based upon the megapixel of the photo taken:

Divide by dpi (dots per inch) rule
To determine print quality for your photo, divide the pixel height and width by the images resolution to find the maximum print size. Example:

          3072 x 2048 image @ 180 dpi = 17.067 inches x 11.378 inches

Per the above, the maximum print size of the listed image is quite large. If you are simply wanting to print a standard 4x6 image then you have some wiggle room to adjust the image. Case in point, the following image was taken with a Canon 10d SLR and has an original resolution of 3072x2048 @ 180 dpi:

While you can make out the critters in the yard the image is not close enough for detail and printing the image may not be something you want to waste money on. But, it can be salvaged by utilizing software.

Continuing with the example, say I want to print the image utilizing 4x6 photo stock. Since this image is in landscape, the final image will actually be 6"x4" or 1080x720 @ 180dpi (6" x 180 = 1080, 4" x 180 = 720). Utilizing software, create a new image that is 1080 wide x 720 high. If you open and paste in the original image you will be able to position the image for a close up of the object(s) you wish to print. Working with the above image, the outcome would be similar to the following image.

As you can see, the distant objects within the photo are now the main subjects as desired and can be properly printed or saved with very minimal effort.
