CSS3 Filters
The CSS3 filter effects provide an easy way to apply the visual effect to the images. The CSS3 filter properties are:

1. blur()  : Blur effect can be applied to an element using the blur() function.

2. brightness()  : The brightness() function can be used to set the brightness of an image. 

3. contrast()  :  The contrast() function is used to adjust the contrast on an image. 

4. drop-shadow()  :  The drop-shadow() function to apply the drop shadow effect to the images like Photoshop. 

5. grayscale()  : The images can be converted to grayscale using the grayscale() function. 

6. hue-rotate() : The hue-rotate() function applies a hue rotation on the image. 

7. invert() : The invert effect like Photoshop can be applied to an image with the invert() function.

8. opacity() : The opacity() function can be used to apply transparency to the images. 

9. sepia() : The sepia() function converts the image to sepia. A value of 100% or 1 is completely sepia. 

10. saturate() : The saturate() function can be used to adjust the saturaion of an image.
