LET'S TRY PHOTOSHOP

Photoshop is a very complicated program, and people tend to forget
how lost they were when they first encountered it.  So let's be really
simple today.

1.  Find Photoshop and start it.

2.  Find four images on the web and save them to the desktop.

3.  Open each image in Photoshop.  Size each image so that its
	height is exactly 400 pixels.

	Make sure you can view the layers on each image.  Each
	image should just have one layer at the moment, but
	soon one image will have four layers, and you'll want
	to see that happen.

4.  Now expand one of the images horizontally so that you have
	room to paste your images side by side like a triptych.
	Except you will have four panels instead of three.

	Students like to drag each image in photoshop so that
	they are side by side, but each still a separate image.
	That's not right.  I want you to copy and paste so that
	one image has four layers.  Notice that you can select
	each layer individually and move it so that you align
	it as you wish.

5.  Change each image so that one of them is black and white,
	another is inverted like a photographic negative, another
	is sepia (that old fashioned brown-red color) -- which
	you have to do yourself using color balance, and
	the fourth one is monochrome blue (like you are in an artsy
	movie and the director is shooting in blue light).

6.  Save your image as gif, jpg high resolution, jpg low resolution, 
	bmp or tif, and png.  You'll find that you have to flatten the
	image before you can save it.  Which one is biggest?
	How much do they vary in size?

7.  Reopen each of the images and 
	(a) try to make the jpg look like the gif (hint:  posterize to 256)
	(b) try to make the high res jpg look like the low res jpg
		(hint:  blur!)
	(c) try to make the gif look like the bmp or tif.  ha ha ha.
		(hint:  you can't, but you can try sharpening
		and maybe painting a few colors here and there.)

8.  Now choose one of the images and apply an art filter.

9.  Put a border around tbe whole thing.  You'll have to make a mask,
	invert it, and pour color.
	
10.  Finally, sign the darn thing at a 45-degree ANGLE in the lower
	right corner, and print it out.

	If the TA likes it, you are done!
