File Management
by Brad Alexander

 

     Listen phello photog enthusiasts, there is NO need to post images that are like half a meg in file size. If you are going to be posting photos, it would greatly help us all if you learn how to use any number of photo editing programs out there. Many cameras even come with their own basic programs. I am not aware of any photo editing software that does not allow you to crop, change the image size and allow you to save at various levels of compression as a jpg.

     For me, I like the file size of 720x480 pixels. A few years ago, I always tried to get the image at or very close to 100k. Sometimes I had to get the physical size of the image much smaller than 720x480 to accomplish this. However, today, high speed is much more available, so 200k is acceptable. You can achieve this in two ways – image size and/or compression. By simply saving as a jpg, you are ultimately compressing the image. However, most programs (if not all) allow you to adjust the level of compression to help you achieve a smaller file size without too much degradation to the image. If you can’t get the image down to a reasonable file size (around 200K) by means of an acceptable level of compression, then just change the actual size of the image. For example, a 720 wide image will be a larger file size than a 640 pixel wide image.

     
Honestly, if you want to share the images then great, we all want to see them. But taking just a couple of extra minutes to prepare your images for sharing really helps us all. I even have high speed and can easily notice when there are 10 images to download at half a meg or more a piece.

     Here are some examples:

540x360 pixels
Compression level= 9
Photoshop CS
129K
Some programs use a compression level from 10-100, some 1-12. The higher the level, the larger the file size and less jpg artifacts visible.
 
720x480 pixels
Compression level= 9
Photoshop CS
192K

 
720x480 pixels
Compression level= 12
Photoshop CS
488K
(huge jump in file size not necessary)
