#4 Scanning (W3 HW)

1. How to scan:

1. Place your image on the scanner, face down, and close the lid.
2. Press the 'scan' button on the scanner, or if you prefer, open up the program on your computer (Brother ControlCentre3) and select where you want to save your file and hit 'scan'.
3. To change the settings of your scan, open the 'customs' options and select the descreen option, appropriate resolution, scan type and document size etc. I think with my scanner, the descreen option is already built in and so, you will not have to worry about turning on the descreen function.
4. Save your scan in a desired location and preferably as .jpeg (in order to upload onto the web) and .psd (use in photoshop).


2. Discuss what the Descreen selection does and why it is important (include the images scanned in exercise 1).

When the descreen selection on the scanner is turned on, the moire pattern scan is avoided and a better resolution of the scanned image is produced. The moire pattern appears on magazines images that have been scanned with the descreen selection turned off.

With my scanner, I think the descreen function is built in and clear images were produced.


3. Explain what resolutions are best for web, print and presentations for fashion.

Unfortunately, my scanner did not have the 72dpi and 360 dpi resolutions.



This magazine image (left) was scanned at 100dpi and there are tiny square patches and the image is not crisp and defined.










The image was scanned at 150dpi (right) and the result is clearer than the image scanned at 100dpi. There are no visible square patches on the image, however, there are faint lines that run across the image.








This is the result of the image (right) being scanned at 300dpi. The image is clear and crisp. The model and the dress are clearly defined and there are no lines or squares.



When scanning images for the print and web, the higher resolution of 300dpi is satistory in producing clear, crisp and defined images. I'm not sure what the outcome of a 360dpi looks like so I will have to wait and see. But if I was using my home scanner, I would select the 300dpi resolution.


4. Fabric and DDS Scans

These images were scanned at 300dpi with 24bit Colour Mode (this was the only colour mode option on my scanner).
- hehe my fabric is a bit wrinkled -
