File Format Exercise

                                     

I'd say that the forrest picture has the best image quality. It shows less obvious pixels, and works with more file formats than the graphic circle does. The graphic circle has the highest quality when saved in PNG(for web formats). It also has better quality when saved as a GIF (because it's a graphic, and has flat color, it will look better when saved as a 

Graphics interchange format -GIF).

On the other hand, the forrest picture has the worst quality when saved as a gif, because it compresses it's colors/file down. The picture doesn't contain any "flat" colors, so it looks worse when saved in a graphic format. This photo looks the best when saved as the HIGHEST quality JPG, and the next best file format would be the "max" PNG.

Notes on File Formats

NOTES -Graphic File Formats:Understanding format choice and image compression

File Formats-

-all computer documents, or files are packaged in different formats

-the format is determined often by the files origin, such as a software program like Photoshop, or a device like a digital camera

Lossy vs Lossless-

-graphic image formats fall under 2 categories-lossy and lossless

-With lossy, image data is “lost” or reduced for smaller file sizes but can cause poor image quality. Can result in showing “compression artifacts” and shows pixelisation.

-Lossless retains image data for higher quality, but larger file sizes

Graphic Formats-

-TIF, JPG, and GIF are the 3 most common formats for common activities such as printing, scanning, and displaying images over the internet

-PNG is a common web format, is high quality, and can contain an alpha (transparency) channel.

-Each format has its own advantages, and disadvantages

File Format:TIF

-stands for tagged image format

-common format for desktop publishing, print, photo, and graphic design

-is a LOSSLESS file format. It retains image data for maximum image quality

-can result in larger file sizes, not fit for display over internet, is not browser compatible.

File Format: JPG

- Stands for joint photographers expert group

-created for digital photo. and works best for photo content

-is a LOSSY format

-can reduce an image file size by 10:1 without showing significant compression artifacts

-level of compression is adjustable

File Format:GIF

-stands for Graphics interchange format

-is best for graphics or images that have flat color or even tone such as a cartoon

-reduces image size by “indexing” color from 3 channels to 1

-is adjustable by changing color bit levels from 1 to 8

-contains no DPI(Dots per inch) data for printing. not a proper format for print

Know your pixels

-TIF and JPG are best for images with pixels that blend in color, these are called “contiguous pixels”

-GIF is best for images with flat, even tone, or “non-contiguous pixels”

Alias vs Anti-Aliase

-Anti-aliase tries to smooth out jagged edges

-aliased is usually more pixelated and jagged
