Optimizing images in Adobe Photoshop:

Tips on optimizing images:
The
images of your case should have been saved in .jpg format. Images should be in
different powers of magnification. Include as many low power views of the case
as possible. The number of the images may be as many as you think necessary.
The best resolution for the images is 800 x 600 pixels.
1) Every capture device should have software to capture images at an optimum
state. Basic colour and brightness, contrast, saturation and hue can be
optimized during the process of capturing the images.
2)After capturing the images in .jpg format, open the file in Adobe Photoshop.
3)In Adobe Photoshop, use the brightness, Contrast and Sharpness, and adjust
these to optimize your image.
4)Try the levels menu. Go to Image ® Levels. The Histogram in the dialogue box
shows how the colors of the image are distributed. The slider box beneath the
histogram provides 3 triangles, one for each of the darkest, medium and
lightest pixels of your image. To make the darkest pixels black, drag the left
slider triangle to the right to the beginning of the histogram; and to make
the lightest pixels white drag the right handed triangle to the left to the
end of the histogram. Now move the middle triangle, known as the gamma point,
to the left to make the medium colors lighter. Another menu in this Levels
Dialogue box is the eyedropper icon. Click on the right (lightest) icon and
then click on the area of your image, which should be white. This is known as
White Balance, and instantly brightens up the image.
