IMAGES FORMATS

JPEG/JFIF

JPEG (Joint Photographic Experts Group) is a compression method. JPEG compression is (in most cases) lossy compression. Every digital camera can save images in the JPEG/JFIF format, that produce relatively small files. The JPEG/JFIF format also is used as the image compression algorithm in many Adobe PDF files.

JPEG is the most suitable format for web design and ho preseve more quality.

TIFF

The TIFF (Tagged Image File Format) format is a flexible format. Some digital cameras can save in TIFF format. TIFF remains widely accepted as a photograph file standard in the printing business. OCR (Optical Character Recognition) software packages commonly generate some (often monochromatic) form of TIFF image for scanned text pages.

GIF

(Graphics Interchange Format) is limited to an 8-bit palette, or 256 colors. This makes the GIF format suitable for storing graphics with relatively few colors such as simple diagrams, logos and cartoon style images. The GIF format supports animation and is still widely used to provide image animation effects. It also uses a lossless compression that is more effective when large areas have a single color, and ineffective for detailed images.

how we did it

sound edition (technical explanation)

First, we recorded our voice with a microphone in the program AUDACITY.
Then, we exported the file in MP3 format.
After that, we searched a music in a web page, and we added it to the audacity MP3 file .

Finally, we uploaded the the MP3 file to HTML with the GOEAR, and we added it in our blog.
