digital images and dimensions/resolution


Starrlight Photo web-size and high resolution images:

“Web/email” images:
8 x 12 inches, 72 ppi. These images are of a size and resolution that is best for using on a webpage, facebook, and sending by email to friends and family for general viewing on their computer.

“Standard High” resolution:
4 x 6 (or 5 x 7) inches, 300 ppi. These images are formatted at a size that is best for the client to make their own 4 x 6 inch or 5 x 7 inch hardcopy prints and are suitable for yearbook awards and powerpoint presentation photos (eg TICA and CFA), ads up to 1/4 page in a publication, business cards, etc.

“Full” size resolution:
Approx. 8 x 12 inches to 12 x 18 inches, 300 ppi (depending on the amount of background cropped out). These images are formatted at a size that is best when the client needs the largest image and best resolution possible, for making large prints, banners or canvases 8 x 10 inches or larger, or for full page ads/graphics in publications, prints for awards plaques, etc. These images receive custom, detailed editing to provide the best possible quality portrait at the correct dimensions needed by the client, so are priced higher than the “standard high” resolution images.

* Please note, if you are going to be using a high/full resolution image to make a wall canvas or large print (larger than 8×10″), please contact me for custom image that has a smaller signature and no copyright symbol.


Digital image formats:

I get a lot of questions about “resolution” when it comes to digital images so will provide a bit of info here about digital image format.

There are a number of ways that digital images are formatted. There are 3 primary specifications that I’ll describe here.

1) Resolution in “pixels per inch” (ppi) or “dots per inch” (dpi) – Pixels per inch refers to how an image is viewed on your computer monitor, dots per inch is a printing term.  They are obviously closely related, if you’re really interested in more specific details you can see the Wiki information or google it.  An image that is 72 ppi will have, per square inch, 72 pixels vertically and 72 pixels horizontally for a total of 5,184 pixels (referred to as size “5 K”). There are many other influencing factors that determine how the images are displayed on your particular computer monitor, again, see the Wiki page or Google it if you want to know more.

2) Dimensions dimensions of the image, such as 4 x 6 inches, 8 x 10 inches, 9 x 12 inches, etc. Digital images are typically formatted with the dimensions best for how they will be used, for example for 4 x 6 inch prints. An image that is formatted as 8 x 10 inches will not be the correct dimensions to print a 4 x 6 inch print without having to be cropped.

3) Compression jpg images are created using a method of compression, usually ranging from 1-10 or 1-100, with 1 being the least amount of compression (better quality, larger size) to 10 or 100 being the highest amount of compression (lesser quality, smaller size).
