Can I make a DIAGONAL marquee?

One way of achieving the same goal may be to use your paths tool
to define your "diagonal" rect. and just change the path to a
selection.
To use the actual rect. marquee tool to make a diag. selection
you would probably have to use another document to rotate the
selection and all kinds of other B.S.

Is it possible to make a DIAGONAL rectangular marquee select? This
would be using the rectangular select tool, not the freehand tool.
Thanks,

No. But you could draw a regular triangle, fill it with something, select
it, skew it or distort it into your diagonal, then save the selection. Or
you can use the Path tool to define your diagonal boundries, and turn the
path into a selection which would be easier.

Here's what I suggest.
1. Add a new layer and make it the active layer.
2. Create a normal rectangular marquee on this layer.
3. Select image/rotate/free and rotate your selection. (You may need
to fill it with something first, otherwise photoshop will complain
that the selected area is empty.)
4. Go back to your background and make that the active layer. Your
rotated marquee can now be used on that. (Hide the extra layer if
necessary, to see what you're doing.)
5. If the rotated marquee isn't in exactly the right place, hold down
Option and COmmand keys both at once and drag the selection area.

By far the simplest way to do this with the most control and flexibility
is to use--you guessed it--Quick Mask.
But what you might not know is you don't even need to use a single
selection tool.
Here's the secret (pay attention, folks!!!)
1) Enter Quick Mask mode, foreground color set to black.
2) Choose the Line Draw tool.
3) Under Line Options, enter a width. This will be one of the
dimensions of your rotated rectangle. Caveat: It must be a number
between 0 and 1000, inclusive.
4) Click and drag over the area you wish to select.
5) Image -> Map -> Invert, or Ctrl-I the entire mask.
6) Exit Quick Mask mode.
And there you have it! The only problem with this, of course, is that
one of the dimensions of your rectangle must be less than or equal to
1000. If you want a larger selection, you would modify steps 2-5 as
follows:
2) Choose the Rectangular Marquee tool. Make a selection at the
size you need.
3) Invert the selection (Ctrl-I).
4) Image -> Rotate -> Arbitrary / Free; rotate and move to desired
orientation and position.
5) Deselect (Ctrl-D), invert the mask (Ctrl-I).
Here we see that there is somewhat less flexibility than in the first
method, and it is more cumbersome. Note that with the line tool, we
can interactively adjust one of the dimensions and position of the
rectangle as well as the angle--at the same time. In the second
method, you need to predetermine both dimensions of the rectangle, and
angle adjustments cannot be done simultaneously with size and position.
You'd be hard pressed to find a solution for which you can continuously
adjust *everything* while still maintaining simplicity, so IMHO I
think the Line tool is the way to go....
Quick Mask rocks. I think with the introduction of layers in 3.0, a
lot of people have forgotten about QM. It's faster and more efficient
to use than both layers and layer masks--I prefer to view the latter
simply as a more permanent version of QM, one for each layer. Paths
are also too time-consuming and are generally better suited for
freehand drawing of curves, a la Illustrator.
happy photoshopping

Easier, I think, would be to use the Cropper tool. Hold down option
when pulling on one of the corners, and it will rotate instead of resize.
It's limited to 45 degrees clockwise or counterclockwise.

Or try this...
1. Go to the Channels Palette.
2. Create a new channel.
3. Drag a white rectangle to the required size....if you
know the pixel dimensions you can set them exactly
in the brushes/options palette of the rectangular marquee.
4. Free rotate this rectangle til happy, or go to arbitrary
rotate if you know the exact angle you want it rotated.
5. Go back to the full colour channel...command zero.
6. Load the channel with the mask...Load Selection is
under SELECT in the menu.
7. Hold down the command and option keys together
and move it to where you want it positioned.
8. Go to Save Selection, this way your mask will
always be there in case you need it.
Channels take up far far far less disk space than layers.
Or you could try using paths in the Paths palette....
they use less space than channels.
Does anyone know....
if holding down the command/option keys while using Free Rotate will
rotate just the mask?
I've never bothered to try it, and I'm too tired to do it now.

By selecting the lasso tool, you can use Alt, hold it down, then left
click where you want the first point of the diagonal to go, then release
the mouse and click in the next point, and you'll be able to see the line
the lasso has and move it into place before clicking again. It's a
little more eye/hand coordinated this way, but it can be done. If you
release the Alt, the lasso will turn into a freehand select line. A couple
of times doing it, and you'll get the hang of it. This is for the PC
version, but I'm sure the Mac has a similar key/mouse combination. Check
out my site for more Photoshop tips and free plug-ins.

How about this?
1) Rotate your entire picture 45 degrees using Rotate Arbitrary.
2) Use the Rectangular Marquee tool to make your selection.
3) Make any modifications that you want to the selection.
4) Select the entire picture again and rotate it back with Rotate
Arbitrary.
The only problem with this is that each time you rotate your picture
it grows in size. When you rotate it back to normal, you will have to
crop it to the correct size.
If, for some reason, you MUST have an actual diagonal selection, try
this after step 2 above:
a) Cut the selection from your picture.
b) Use Paste Layer to paste your cut section into a new layer.
c) You'll probably have to move your selection around to get it into
the exact position it was in before the cut.
d) Rotate the picture back.
e) In the pasted layer, select the area that was not pasted with the
Magic Wand and then Invert the selection.
f) Cut the selection and paste it into the original layer.
This will give you a diagonal selection in the original layer. Whew!
I don't know if I would want to go through all of this very often,
though.

Easiest way: use the pen tool. click, click, click, click, "Make
Selection" (from the paths pallette), done.
