Week 2 - Scanning Process & Image Modes

- SCANNING - 

How to scan in a UTS computer lab:

1. On the desktop click on the 'Macintosh HD' icon.

2. On the left hand side column click on 'Applications'.

3. Scroll down till you come across a program called 'Hewlett-Packerd' and select.

4. Select 'HPScan'.

5. Choose to scan a 'picture'/image

6. Place your item(s) on the scanner and click 'scan' when you are happy with the object's position etc.

7. Change the resolution of the image (dpi) to the appropriate number, 72-96 dpi for internet/blog posts images, 150-200 dpi for digital/lazer inkjet printers or 300 dpi for commercial printing. For this task change resolution to 300 dpi.

8. Once scanned onto the computer, adjust any setting (saturation/shadows/hue etc.) necessary.

9. Save to the 'Public' folder, in 'D' folder, in 'DFC' folder, in 'S' for Simone Yow - rename files if necessary.

10. Now that it is on the UTS public server, transfer these images to your USB as a back up/portable & transferable file. 

- IMAGE MODES -

RGB (Red, Blue, Green) is the primary mode for graphics and has a smaller file size than CMYK suitable for Web images.

CMYK (Cyan, Magenta,Yellow and Black)are pigmented colours that printers use which is why all RGB muct be converted to this mode before printing.

Greyscale changes the image into different shades of grey/black/white (approx 256). NOTE: when you convert an image to this mode you CANNOT go back.

Duotone- two colours

Bitmap- Black and White
