You can enhance your photos in Photoshop Elements by adding blur, replacing colors, or by cloning part of the photo. Use the Blur tool to add blur to your photo, the Brush tool to replace colors, and the Clone tool to clone part of the photo. You can select these tools from the Toolbox. For information about the Toolbox, see Tools.
The Blur tool softens hard edges or areas in an image by reducing detail. Blurring a busy background can bring your subject more into focus. You can also use Blur filters for this purpose. For more information on Blur filter, see Blur filters.

The Color Replacement tool simplifies replacing specific colors in your image. You can paint over a targeted color—for example, a yellow flower in an image—with a different color, like red. You can also use the Color Replacement tool to correct colors.

The Clone Stamp tool paints with an image sample, which you can use to duplicate objects, remove image imperfections, or paint over objects in your photo. You can also clone part of an image to another image.

Brush
Sets the brush tip. Click the arrow next to the brush sample, choose a brush category from the Brushes pop‑up menu, and then select a brush thumbnail.
Sample All Layers
To sample (copy) data from all visible layers, select Sample All Layers. To sample data from only the active layer, deselect this option.
Opacity
Sets the opacity of the paint you apply. A low opacity setting allows pixels under a paint stroke to show through. Drag the slider, or enter an opacity value.
Mode
Determines how the source or pattern blends with existing pixels. Normal mode lays new pixels over the original pixels.
Aligned
Moves the sampled area with the cursor as you begin to paint, regardless of how many times you stop and resume painting. Select this option if you want to eliminate unwanted areas, such as a telephone line across the skyline or a rip in a scanned photo. If Aligned is deselected, the Clone Stamp tool applies the sampled area from the initial sampling point each time you stop and resume painting. Deselect this option for applying multiple copies of the same part of an image to different areas within the same image or to another image.

If you like the style of an image, you can apply its style properties to another image. You can work with a set of images, apply styles, and choose to update the image with the style that produces the best results.
Note:
When you apply styles multiple times, the effect is not cumulative. Only the last applied style is saved.

-
Intensity
Controls the amount or intensity of the style to transfer. The maximum value implies that you want to transfer 100% style of the style image.
Clarity
Improves the local contrast of a stylized image. The contrast of the slowly varying intensity regions is enhanced, bringing out crisp details in darkened regions.
Transfer Tones
Transfers the tones of the style image. For example, if the style image is black and white or sepia, and the image to which you want to apply Photomerge Style Transfer is colored, selecting Transfer Tones transfers the style tone (black and white or sepia) to the colored image.
