Question

its for power point i need the picture lighter so i can put it on the back without changing the font so much

Answer 1

If you insert your picture on the slide, then you can use the picture toolbar to change the brightness and contrast of the image.

If you insert the image as the background, then you can not change the color to lighten it.
