Layer Masks, then use of Rulers and Guides
In the second example, the same picture is flipped horizontally and laid on top of itself (inverted as well). We use the layer mask and the gradient tool to transition from one layer to another equally across the entire image.
Below these layer mask examples, you will find two different uses of rulers and guides. These are simple tools, but ones that I cannot live without (okay, a slight exaggeration).
work on kelly first...use the magic wand to slect the man
to add the isolated part of the background to the selection,
hold down the shift key and click in that area a second time
remember, in cases like this (plain background)
we first select the background, then go up to menu bar => select => inverse to get the "non-background"
click on the other image (quarry2)
paste (command "v")
use the gradient tool to draw a line vertically from his bag to the bottom of this feet
click the quick mask tool again
command "d" will get rid of wanted "marching ants"
create a duplicate layer
select top layer and do two things to it...
flip that layer horizontally
use edit => transform => flip horizontal
(rather than image=>image rotation)
make color-picker black and white
choose the gradient tool in the toolbox
click "edit in quickmask mode" at bottom of toolbox
draw a line across the image from left to right
click out of quickmask mode...you should see marching ants
hit the delete button
now the bottom layer should show through...feathered nicely
Guides and Rulers
use the move tool and go into the ruler area itself
click on that ruler area and drag the mouse into the picture area (try the top)
a guide will appear
drag it to the middle of the image--it should snap to the exact center
do the same from the side ruler, drag the guide to the center again
use the guides in conjunction with markings on the rulers to create grids or to square things up
with this first example, the individual pictures of the triptych will "snap to" the cross-hairs created by the guides
(one can also align things by their edges, rather than their center)
Please make a horizontal triptych similar to the one above.
Square up a picture
make a duplicate layer
fill the bottom layer with white
click back up to the top layer and cut away the non-picture
or use the polygonal lasso tool right now to be quicker
then go to menu bar, select, inverse
this will select the non-picture/painting...delete
next, drag four guides into the image
arrange/place the guides using the measurements on the rulers to make a perfect square (in this case)
distort the top layer (picture/painting) to match the guides...
force the picture/painting to conform to the perfect square created by the guides
