[These Supplementary Functions Are Used During Retouching.]

Changing resolution
There are two methods for changing image size. One involves changing the number of pixels. In the other, the number of pixels is not changed. ItÍs important to understand when to use each method.
Crop Tool
Use the Crop tool to eliminate the unnecessary part of an image, and crop the image to fit the printer paper.
Unsharp mask filter
Use the [Unsharp mask filter] to increase edge definition, making the photo appear sharper.
Copy Stamp Tool
Specify the location of the image to be copied, and copy it by dragging. With the retouch of images, this tool is often used to erase dust or dirt.
Adjustment layer
Use the layer to redo color tone correction any number of times without degrading an original image. If you fail to do the process, delete the layer to erase the effect. It is convenient as you can adjust the processing even after completing the correction.
Level compensation
Use level compensation to adjust the gradation of a photo. You can use this feature for retouching.
Color balance
Use the slider controls in the Color balance dialog box to correct pictures with colorcast.
Tone curve
Use the tone curve to adjust brightness and contrast.
Hue and saturation (chroma)
The three components of color are hue, saturation, and brightness. Use this function to control hue and saturation.
Selecting a specific color level
This dialog is useful for changing one specific part of an image. Use this to improve color in only a certain part of the picture.
