Requirements for Calendar Photos
Posted: Wed Nov 02, 2005 9:33 pm
I’ve had numerous photo submissions for the calendar (including new ones for 2007 - thank you all very much!) – some of which were usable, some of which were not. Although we’ve discussed what is required for a calendar photo in other threads, I thought I’d post the requirements centrally, so all could reference it easier in the future.
General requirements:
The printer requires the image to be a resolution of 300 dpi (dots per inch) when sized to 11†x 8.5â€. An image of this size probably occupies 2mb – 3mb on your hard drive. Since resolution is inversely proportional to size, an image that is 300 dpi sized to 5.5†x 4.75†becomes 150 dpi when enlarged to 11†x 8.5â€. This means that that “really great pic†you may have as your wallpaper on your computer probably won’t work because it is probably 72 dpi or 96 dpi or 150 dpi and 2†x 3†or thereabouts. The fact that the image occupies the entire screen is a function of Windows (or other operating system) enlarging it electronically. Despite the fact that it may “look great†IT WILL NOT WORK unless it is a high resolution image (i.e. 300 dpi or greater).
Digital Images:
If you are taking digital pictures make sure that you are taking a high resolution image that will meet the resolution/size requirements mentioned above. If you do that, the image will be usable.
Print Images:
If you have a print photo, you can scan it and specify the resolution and size at the time the scanner creates the digital image. If you do not have a scanner, I can do it for you. I have the capability to scan print, negatives, and slides. NOTE: Photographs taken on film with an ASA of 400 or greater may not be usable when scanned and enlarged. This is due to the grain of the film. The faster the film (higher ASA number) the “grainier†the image when it is enlarged. This WILL show up on the scan. I have had several print photos that were taken on ASA 400 that looked fine as a 4 x 6 print, but looked terrible when scanned and enlarged. ASA 200 may work better. Most professional photographers never shoot anything faster than ASA 100 in order to maintain a crisp/clear image when enlarged.
How can I tell if my picture will work?
Open up the picture in a photo editing software. If you have MS Windows, you can open it with “Paint†which comes standard with Windows under the “Accessories†section. You then need to find the menu option that will give you the “Properties†or “Attributes†of the image. This should give you the resolution and size of the image (in Paint, select “Image -> Attributesâ€). Most software packages will give you the image size in pixels - 300 dpi @ 11†x 8.5†works out to a pixel dimension of approximately 3390 x 2610. If your image is in the vicinity of these dimensions it will probably work.
If all of this is too convoluted or confusing have no fear, you can always contact me to find out if your particular image will work. Just email it to me and I’ll be glad to let you know.
Now, go take some pictures! Be creative! Inflight, on skis, on floats, backcountry, on the ground, or any other interesting setting you come across.
