Colouring Operations >></strong></font></p>
<p align="left"><font color="#000000" face="Arial" size="2"><strong>This section gets you
started colouring your first photo in BlackMagic.<em>You must have successfully completed
the steps in the <a href="bmdoc21.html" target="_self">previous section</a> to be able to
carry on from here.</em></strong></font></p>
<p align="left"> </p>
<p align="left"><font color="#000000" face="Arial" size="2">In the previous section, you
concluded by getting a source black & white image into BlackMagic, either from the
disk, or from a scanner; either way, if you managed to do this successfully, you would now
see the caption on the first button on the top panel changed to <em><strong>"Clear
Image"</strong></em>; click this button to close the image window.</font></p>
<p align="left"><font color="#000000" face="Arial" size="2">To get started colourizing
your first photo, follow the steps to load an image from the "samples" directory
located in the folder where you installed BlackMagic; the image is called
"beach.jpg" (or beach.bmp). Depending upon the version of your BlackMagic
software, you would see a screen similar to the following.</font></p>
<p align="center"><font face="Arial" size="2"><img src="bmdoc2210.jpg" alt="BlackMagic with an image loaded" WIDTH="717" HEIGHT="535"></font></p>
<p align="left"><font color="#000000" face="Arial" size="2">If you do not see a pop-up
menu over the image, place the mouse cursor anywhere on the image and CLICK on the right
mouse button to display a menu similar to that shown over the image above. (In
Business Edition upwards, the corresponding palette may also be selected from
the listbox "RLC Palettes" by clicking on the desired list item). </font></p>
<p align="left"><font color="#000000" face="Arial" size="2"><strong><em>In BlackMagic, you
do not normally pick individual colours to paint (though you can), as you would need to in
some other painting software packages - instead, you simply choose the type of object that
you desire to paint from the pop-up menu; BlackMagic dynamically and automatically tunes
the colour variations, depending upon the image area you want to paint, and the object
type that you select.</em></strong> </font></p>
<p align="left"><font color="#000000" face="Arial" size="2">Now Scroll down in the pop-up
menu to select <strong>"Sky" </strong>then select <strong>"Clear [Day <u>1</u>]"</strong>
from the sub-menu; the menu will disappear. You have just told BlackMagic what type of
object you wish to paint; now you have got to tell it where that object is on the image.
To do this, you first select a tool from the <strong>"Tools" </strong>bar
(second panel on main screen from the top). For our current purpose, we will select the
"<strong>Select Paint" </strong>tool (</font><font face="Arial" size="2"><img src="bmdoc225.jpg" width="32" height="31" alt=""Select Paint" tool button"></font><font color="#000000" face="Arial" size="2">) Do this by clicking on the corresponding button.
Also make sure that the "Check-box" next to "Overwrite" label is
checked, and the one next to "Layered" is not checked. Your tool-bar should now
appear similar to the one shown below.</font><font face="Arial" size="2"><img src="bmdoc227.jpg" alt="Partial view of the tools panel with above selections" vspace="8" WIDTH="350" HEIGHT="56"></font></p>
<p align="left"><font color="#000000" face="Arial" size="2">Now move the mouse cursor back
on to the image then <em>drag </em>to draw a rectangle that closely fits around the
"sky portion" of the image, as shown below-right (you <em><strong>drag</strong></em>
by holding down the left mouse button, while moving the mouse around; as you do this, a
rectangle appears to grow/ shrink along with the mouse movement, just as a rubber-band
would). Let go of the left mouse button, when the rectangle is just the right size (see
image below).</font></p>
<p align="left"><font face="Arial" size="2">
<img src="bmdoc228.jpg" alt="Selection Rectangle around the "sky" using the "Select-paint" tool" WIDTH="419" HEIGHT="479"></font></p>
<p align="left"><font face="Arial" size="2">Soon as you let go of the left mouse button
(stop dragging), BlackMagic will start applying the colour scheme that you have chosen, to
the area you selected. Repeat this process to: </font></p>
<ul type="circle">
<li><p align="left"><font face="Arial" size="2"><em>pick the object type <strong>"Water"</strong>
from the pop-up menu, then select <strong>"Ocean Blue"</strong>, then drag as
you did before to select the portion of the image representing the water body; </em></font></p>
</li>
<li><p align="left"><font face="Arial" size="2"><em>then again, pick the object type <strong>"Earth"</strong>
from the pop-up menu, select <strong>"Light"</strong> from the sub-menu, then
drag to select the rectangular region representing the 'beach area.</em></font></p>
</li>
</ul>
<p align="left"><font face="Arial" size="2">If you make a mistake at any step (such as
over/ under select an area), just click on the <strong>"Un-do" </strong>button
at the bottom of the image window to return to the previous state (you may need to
'Enable' "un-do" by clicking on the check-box next to the button, so that it
appears "checked").</font></p>
<p align="left"><font face="Arial" size="2">Once you have followed the above three steps
correctly, you should have an image that looks like: </font></p>
<p align="center"><font face="Arial" size="2"><img src="bmdoc226.jpg" alt="Surf image colourized after three 'Select-paint' operations" WIDTH="316" HEIGHT="338"></font></p>
<p align="left"><font face="Arial" size="2">Now this is far from perfect, but not bad for
a few seconds and 'mouse-clicks' worth of effort. Actually, we will continue to refine
this image to a much better quality. To begin with, notice the edge towards the right of
the image, where the ocean ends and the beach begin; the end part of the surf falling on
to the beach takes on the colour of the beach too abruptly (<img src="bmdoc221.jpg" alt="Beach & Surf border before smoothing" WIDTH="221" HEIGHT="44">). Let us smooth this out first with the <strong>"Smart
Brush"</strong> tool. select it by clicking on the (<img src="bmdoc222.jpg" alt="The "Smart Paint" tool button" WIDTH="37" HEIGHT="33">) button on the "Tools" panel. At
its worst, this tool works like a regular 'paint brush' tool (as in other paint programs);
but it can work much smarter, taking care not smear colour on unwanted surrounding areas
(refer to the Reference section for more details). </font></p>
<p align="left"><font face="Arial" size="2">For our present requirement, the default
behavior will suffice. Now pick the <strong>Water -> Ocean Blue </strong>colour scheme
from the popup menu, as you did while colouring the Ocean. Because we want to 'layer' the
subsequent painting on top of the existing rendering, make sure that the
"Layered" check-box is in the "Checked" state (refer the
"Tool" panel image above). Now, move the cursor on the image area representing
the ocean, and begin dragging (move mouse while left button is depressed). The cursor will
change to a round brush shape, and the 'Ocean Blue' colour scheme will be <em><strong>Layered
</strong></em>on top of other colour schemes that the brush encounters (Light Earth in our
case). Slowly continue this 'dragging' behavior, moving the brush in side-to-side strokes,
while moving down towards the beach area with each stroke, until the colours at the edge
