Digital Image Essentials

Camera File Formats:

• JPEG is the most widely used file format in photography. JPEG file format throws away information through a process called lossy compression
• RAW file formats contain all of the data that the camera format captured. RAW files still apply compression to files, but the quality of the image is not compromised.
• DNG format, digital negative format, is another RAW file format created by Adobe.

Working or Master File Formats:

• PSD: Saves all Photoshop options, including layers, type, shapes, adjustment layers etc.
• TIFF: Also saves all of these options (both Lossless compression)

Output Formats:

• To reduce file size, output file formats often flatten and compress images, making it easier to upload or transfer files more quickly.
• For print, you will want a file with more information so keep files as a PSD or a TIFF

Flattening images:

1. Make sure that you have saved a version of your project that is not flattened if you think you will need to make further changes to a layer in the future.
2. Make sure that all the layers you want to keep are visible.
3. Choose Layer > Flatten Image, or choose Flatten Image from the Layers panel menu

5. Paint inside the part of the image you want to select. 

• The selection grows as you paint. If updating is slow, continue to drag to allow time to complete work on the selection. As you paint near the edges of a shape, the selection area extends to follow the contours of the shape edge. 
• Note: If you stop dragging and then click or drag in a nearby area, the selection will grow to include the new area.

2. Release the mouse button or keep it pressed, and then move the pointer along the edge you want to trace.

3. The most recent segment of the selection border remains active. As you move the pointer, the active segment snaps to the strongest edge in the image, based on the detection width set in the options bar. Periodically, the Magnetic Lasso tool adds fastening points to the selection border to anchor previous segments.

4. If the border doesn’t snap to the desired edge, click once to add a fastening point manually. Continue to trace the edge, and add fastening points as needed.
