I love image. I love editing image. Fortunately, I met ColorSync Utility.
ColorSync Utility can help me edit my image. I can Resize Image, Apply Profile to image and do Image Correction.
First of all, we need to open our image(s) with ColorSync Utility. You have to highlight image(s) that you want to edit. Then, Control-Click on one of those images. After that, a menu will pop-up. From this menu, mouse hover on Open With and choose ColorSync Utility to open this image(s) in its field.
If you want to resize your image, you can click on the forth toolbar button, i.e. Adjust Image Size. A pane will appear. Inside this pane, you can see Image Size, Scale Image and set image Quality. Scale Image can be done according to its scaling, width or height. For example, if you have image with size 500×300 and you resize your image with width 400, you will get 400×240 image result.
Editing image with ColorSync Utility includes Applying Profile. You can apply Sepia Tone, Blue Tone, and many others profile.
Also, you can do Image Correction to your image. This image correction includes Exposure Level, Color Level (White-Point and Black-Point), Gamma Level, Color Adjustment (Saturation, Contrast and Brightness), Sharpness and Sepia Level. By setting White-Point to black and Black-Point to white, you will have inverted image color.
