pool ball and square apple demo

First we made a background using gradient tool. then made a selection of a round circle using elliptical tool and filled it with orange. Then used dodge and burn tools to add some shading on the ball.

Then selected "select pixels" and saved that selection. Then made another selection and also saved it then opened both selections at the same time and then pressed edit>fill use:white and then with using mask tool and low opacity black brush I deleted parts of filed area.

then made a shadow  with brush tool and then made a white circle in the middle of ball and wrote number 1 with type tool.

 I think that this technique is realy good for creating realistic 3d looking simple object if you dont have 3d software or a actual object to take photo of.

Next we opened photos that we downloaded from moodle.It was photo of apple and a photo of sliced apple.

First i opened an image of red apple and increased the size of canvas by selecting crop tool and expanding crop area beyond current image boundaries  then on a new layer I made a cube using bright (green) color. Then to make square apple I opened liquify and with freeze mask tool i froze pixels inside the green cube and then with forward warp tool i pushed all the pixels of apple that haven't been frozen into the middle of apple. And it ended up looking like this.

Then I deleted green cube layer and created new layer in wich by using small white brush i made edges of apple more visible.

 

After that i created shadow of apple. First i created new layer under apple's layer and with black brush created a shadow but the hardness of shadows edges were to high so i used gaussian blur and reduced opacity.

Then with lasso tool i selected the front wall of apple and opened a sliced apple image then selected the whole image and copy pasted sliced apple in red apple's image by selecting copy merged and then going on red apples image and selecting paste into with apple's layer selected.

With this technique you can change shapes of all kind of things: Basketball's ball, banana, tennis ball etc.
