| Scanning and Coloring in
Photoshop By : fireEyes tailchaser
Part 1...Scanning,
Levels/Curves, Modes
Start off by scanning in your sketch in gray scale mode.
Scanning in color mode will only add unwanted noise, and black & white won't have
enough detail. I recommend scanning in at no less than 150 dpi.
Now you have your sketch open in Photoshop. The first thing
you want to do is work with the Levels and/or Curves. If you have never used either of
these before, it can be a bit tricky at first. Go Image>Adjust>Levels or
command+L (CTRL+L for PC users) You should see something like this:
Make sure that the preview check box is checked so you can
see how the changes you make affect your image. Start off by clicking the absolute black
eyedropper (I have outlined this button in red on the image above). Next, click on the
darkest area of your sketch; I usually choose the pupil of the eye for this. Next, click
the absolute white eyedropper (I have outlined this button in yellow on the image above).
Now click on the whitest area of your sketch. To make final adjustments, use the center
triangular slider (outlined in blue above). There are many ways to use the Levels tool, so
experiment. This is simply the method that I find to be the most useful. Here is an
example of what a sketch looks like before and after proper leveling:
Another interesting tool that I have yet to master is the
curves tool. I've found this feature useful when doing art with solid outlines, in a comic
book or anime style. It's a great way to clean up sketches. Basically, it gets rid of all
the midtones and keeps only black and white, making the image look a bit like a page from
a coloring book. Go Image>Adjust>Curves or
command+M (CTRL+M for PC users) You should see something like this:
Since I really don't know how this tool actually works, the
only way I can explain how to use this is to start dragging points up and down off the
line graph. After a while, you know where to push and pull, and you can get the desired
effect pretty quickly. It's really just something you have to practice with. Here is an
example of how an image can look before and after proper use of the curves tool
(sorta...I'm not very good with it):
Another important thing you need to do before you start
adding color is to switch into RGB mode. Go Image>Mode>RGB
Color. If you left the image in grey scale mode, you would be able to paint
with nothing but greys, and that's not good...unless you want that of course.
Part 2...Layers,
Painting, Blend Modes
If your layers palette isn't showing, go Window>Show Layers. Create a new layer below the layer
with your sketch. Fill this layer with solid white. Next, set the sketch layer into
Multiply mode. Do this by selecting the layer and choosing Multiply from the drop down
menu at the top of the layers palette. This basically removes all the white from the layer
so that it is transparent. Now you can color underneath the sketch!
Now to start work on the background. I always start with
the background because it determines the light source. I have a very hard time with
lighting and such so I need a hard, defined light source before I can start any of my
shading. Start at the furthest point away from the viewer, and work your way up. Add a new
layer for each step, naming each one along the way so you don't get lost. For example, I
like to keep the sky and clouds in the bottom layer, then create a layer on top of that
for foliage and trees, then a layer on top of that for the ground. Once the background is
complete, continue working forward with the subject matter. I often create different
layers for each separate color, and then create a separate layer for the highlights and
shadows. All of this is up to your own artistic abilities; it's nothing that I can explain
to you in a tutorial :) And be sure to save often! There's nothing worse than spending an
hour in Photoshop coloring and then having it freeze up on you right as you realize you
haven't saved yet.
Experiment with the different tools. I commonly use the
paintbrush tool for all my coloring, and the dodge/burn tools for shading. I also use the
airbrush for coloring and shading of some things for a softer effect. The rubber stamp
tool is great for repeating textures. With practice, you can get some very realistic,
natural looking textures. You can also get some neat effects with the smudge and blur
tools, especially when working with clouds and the sky. I've found many uses for just
about every one of the tools in the tool palette. Try them out and experiment.
Another thing I highly recommend experimenting with is
blending modes. Multiply is only one of the many different modes as you may have seen from
the drop down menu earlier. Try them all out and see what effects they have on your
different layers.
Part 3...Final Touches,
Saving For the Web
Once you are done with your picture, keep the layered PSD
file; you may want to go back sometime and change something, or make a print. You may want
to run more Levels on the image overall. Also, there are many more options under the
Image>Adjust menu. One I often use is "Hue/Saturation" because I usually end
up coloring things far too brightly :) Play with them all until you get you image to the
point you want it.
If you are going to post this image on the web, you will
want to optimize it. Go Image>Image Size. In the Resolution box, type in 72 which is
screen resolution. This will greatly decrease your file size. Enter the desired
dimensions, making sure that the Constrain Proportions
check box is checked. I usually enter 700 as the dimension for the longest side. You are
now ready to save. Go File>Save for Web. Click on
the 2-up tab, which will display the original image on the left with the optimized on the
right. Under the settings menu on the right, you will most likely want to choose JPG
unless your picture has very hard, solid lines and colors with no gradients. Adjust the
compression settings until you come up with something acceptable. Be sure to keep an eye
on the file size underneath the image; I try to keep my images under 50k. Anything over
100k really isn't at all reasonable. |
