Photoshop/ practice on different effects and adjustments

In this session we were shown how to invert a colour photo into black and white photo and some other effects using Photoshop.
There are two ways of inverting a colour photo into a black and white photo. First is by Selecting the image -> Image -> Mode -> Gray scale

the original photo

Inverted into Black & White photo

OR Select -> Adjustment -> Black and White

We were shown how to bring colour to black and white image by Duplicating the layer with the original photo, changing it to an Black and White image and then playing with the ''Opacity'' - by this way we bring back colour to the image.

The photo after inverted it into a Black & White photo, and then bringing back colour with the ''Opacity'' tool

We were show how to put a different colour to the image. We had to create a new layer, fill it with the colour we want and then click on ''Multiply''. That blends the original photo with the colour. Then we can play around with the opacity to change the intensity of the colour.

We were shown how to put a photo over another photo.
Choose a photo. Create a new document with a photo we want to place above. Then go to Edit-> Copy. Go back to the document with the original photo - Edit -> Paste special - Paste into, then play with the ''Opacity'' to reveal the photo under.
