  2. What is a TIFF and JPEG? • TIFF is the format of choice for archiving important images. • JPEG is a format for compressing image files.

  3. TIFF(Tagged Image File Format)Pro’s • No image data is lost. • Better image quality than JPEG. • Good for images that will be manipulated in a photo editing program. • More tolerant of poorly exposed images – similar to print film. • Saved at the camera’s max color bit depth, per channel image which can represent 4096 shades for each (red, green, blue) color.

  4. TIFF(Tagged Image File Format) Con’s • File size is very large, resulting in slow saving of image between shots. • Camera processes the image when saving it to TIFF, so the person still needs to make sure that they set the camera properly. • Still need to make sure that exposure, white balance and color saturation are properly set because fixing these in the photo editing program will make the picture not look as good. • Overkill for typical snapshots or to send by e-mail.

  5. When to use TIFF! • Weddings and other once in a life time images. • Fine art images

  6. JPEG(Joint Photographic Experts Group)Pro’s • The file is small which means you can fit more images in a memory card. • Open standard format can be universally viewed by nearly any web browser. • If the image is properly lit and the exposure is properly set, the image quality is quite good for prints similar to slide film. • Often you can set the image resolution which lets you save a smaller image that is easier to post to the web or send by e-mail without any post processing. • Prefect format if you are planning on doing some limited image editing on the computer

  7. JPEG (Joint Photographic Experts Group) Con’s • File is reduced to an 8 bit per channel image which can only represent 256 shades for each (red, green, blue) color. • Image is compressed by taking pixels of similar color and making them the same color. • Every time the image is saved more of the image data is lost. You will probably not notice any significant change in image quality until you have saved it 10 or more times. More saves are required before significant image degradation can be noticed in larger images. • Wrong format for images that will be changed in a photo editing program. • Camera processes the image when saving it to JPEG so some image information is lost.

  8. When to use JPEG! • Snapshots of family and friends that will not be edited beyond simple cropping and red eye reduction. • Images sent by e-mail. • If all the camera settings are on automatic, then chances are JPEG will be fine.

  9. The proof that TIFF is better!
