Don't be afraid to use your digital camera. I know there are a lot of buttons and menus. This can be very confusing, but look for the information on image size and quality and set the camera to auto. This is usual in a chart. Here are some examples.

Image Quality:

To reduce file size and memory requirements images are compressed using JPEG compression. JPEG compression analyzes images in blocks of 8x8 pixels and selectively reduces detail within each block. At higher compression ratios the block pattern becomes more visible and there may be noticeable loss of detail.

These are the quality settings for the camera you will be using during the workshop. Your digital camera may have different settings

Option File Format Description
HI TIFF No Compression
FINE JPEG file size reduced to roughly 1/4 of original
NORMAL JPEG file size reduced to roughly 1/8 of original
BASIC JPEG file size reduced to roughly 1/16 of original

Image Size:

Image size is the actual pixel dimensions of the image.

These are the file size choices for the digital camera you will be using during the workshop. Your camera should have similar choices if it is a 3.3

Option Size(Pixels)
FULL 2048 x 1536
XGA 1024 x 768
VGA 640 x 480

Taking Images for E-mail and the Web:

Your camera stores images as TIFF and JPEG formats, which can be viewed with a wide variety of image software. JPEG images can be displayed in a web browser such as Netscape Navigator and Internet Explorer. This makes it ideal for transmission by e-mail or to fit in the browser window.

If you are going to use the images directly from the camera, it is important to keep your file size as small as possible for faster transmission. Keep your image size 640 x 480. This will allow the viewer to see the whole image in the browser and keep the quality setting on the lowest. This will let you take the largest amount of images and let people view them quickly, keeping the download time to a minimum.

Taking Images for Print:

When taking images for print you want the quality and image size as large as possible considering the final size of the image and the number of images that will fit on your memory card.

To calculate the print size divide the pxels by 200. As you can see you need to use 1024 x 768 at least for a 5 x 4 if you are not going to crop the picture.

Option Size(Pixels) Appox. Print Size
FULL 2048 x 1536 10" x 8"
XGA 1024 x 768 5" x 4"
VGA 640 x 480 3" x 2.5"
