OK, so yesterday I was playing with the GIMP 2.2, and last night I 
played with my dad's copy of PhotoShop Elements 4.0.

The problem basically seems to boil down to the fact that it is 
virtually impossible to draw with a mouse. Drawing with the GIMP, all 
the lines come out horribly wobbly. PhotoShop seems to smooth the mouse 
input somewhat, so lines come out less wiggly.

But even so, no matter what software I use, if you move the mouse in a 
circle, it draws a square with rounded corners. It seems the mouse is 
very keen to move in the horizontal and vertical directions, and resists 
moving in any other directions. Very irritating...


kinda tempted here... (Who knows? Maybe some kind soul will get it for 
my birthday...)

I didn't get very far with the GIMP. The extreme uncontrollability of 
the lines made me give up rather quickly. PhotoShop seems much better in 
this regard, although I still couldn't get decent curves out of the 
cheap optical mouse.

I did play around with layers. Apart from PhotoShop mysteriously 
changing the active layer every 3 seconds, it worked quite well. I had a 
go at scanning one of my drawings, inking it up, colouring and 
counter-shading it.

One thing I did have a problem with is that the brush tool draws 
beautifully anti-aliased lines, but then the flood fill tool doesn't 
fill right up to the edges. It leaves a useless white gap around the 
edges of the lines. Presumably there's a simple way around this?

Also, I haven't yet figured out how to fill in the counter-shading 
without accidentally drawing over the outlines. (But I didn't really 
look into it very much, so it might be something simple.)

I also had a go at reading the paper manual - but, apart from several 
*extensive* chapters on how to import, catelogue and organise your 
photos (yeah, like I care), most chapters were 1 page long and said 
"hey, yeah, there's this cool feature - see the online help for more 
info". Very useful.

There are lots of PS tutorials on Youtube. Most are for the full version 
(not Elements) but some of the tricks probably apply too.

The "You suck at Photoshop" series is both useful and funny (and sad...).

Try turning off mouse pointer acceleration in control panel (I think it's 
called "Enhance Pointer Precision" now) - the algorithms used in Windows are 
quite complex to make the mouse move around in a "natural" way, but are 
useless if you're trying to draw something carefully.  Turning off 
acceleration makes it a linear relation between mouse movement and pointer 
movement.

IIRC one of the improvements in Vista was that pointer acceleration is done 
on a vector basis rather than on the x and y axis separately, which would 
probably explain why drawing a circle gives a rounded square in XP or 
earlier.

One of the reasons I prefer dealing with vectors.

Yeah put your brushed lines on one layer and the flood fill on another,  
not sure of the defaults in Elements, but you can set the background of  
any new layer to transparent. So let's say you create your brush strokes  
on one layer then add in a graduated flood fill on another, move that  
layer beneath the brush stokes and the antialiasing will allow the fill to  
come through. Then add another graduated flood fill in another layer, put  
it between the other two and change its overall transparency. :-)

Outlines on another layer. If in doubt layer it.

Yeah. That and the fact that you can continually *change* the line after 
you've drawn it...

Um... how do you fill in a shape if it's in another layer?

Hmm, interesting...

In PSP there's a check-box in the Fill tool that says "Use all layers". 
Check this and it will do the flood fill in the current layer but using the 
other layers to check for boundaries etc (or whatever settings you have).

You can create a mask from the layer that you use as a reference, save it and
import it into the fill layer. Masks are good tools as well they limit the
drawing area for you.

Get a better mouse. I can draw reasonably well with mine (Logitach laser
mouse), though I still prefer the tablet if I'm doing anything more than a
couple minutes fiddle.

Thanks for the tip. Doing this does result in a small increase in 
controllability, but not very much. It's still infuriatingly hard to 
draw anything half-decent. (And it makes the mouse rather slow and 
unresponsive when you're just trying to work Windoze. So I'll probably 
leave it how it was.)

It seems clear to me now that I need a decent input device if I'm 
remotely serious about this course of action.
