"I
have taken this photo during my military duty years, with a primitive
camera. It would be nice to have a sharper picture, with some zooming.
Perhaps a little coloring wouldn’t hurt either."

Just like the fairy in the tale, we can only grant you half of your wish. This time, it is coloring the photo.
About sharpening:
In
the photo we received, the focus is somewhere on the tiny flowers in
the foreground, but the whole of the picture is strongly blurred. With
today's photo editing technology, there isn't a tool that could conjure
details onto a picture lacking them. Sharpening increases the
contrast on the borders of areas with a certain lightness. Thus, it
produces contrasty edges but that would only give us blots with sharp
edges instead of blots with blurred ones. And a huge amount of noise as
garnishing. You can see this clearly on the picture above. There are no
new details, we cannot see the script on the side of the rocket (if
any), flames don’t look more detailed. Contrast did increase, although
along with noise, and the blot-like effect remained as well.
Sharpening should provide the illusion of detailedness, which is
impossible with this photo. The magic you sometimes see in movies—like
identifying a car’s license plate from half a mile based on a blurred
CCTV image—is, well, quite an exaggeration. Still, reducing image size
can be an effective trick, which does provide the illusion of
detailedness. At least, when compared to the original.

The next move is the preliminary enhancement of brightness and contrast. We used Image/Adjustments/Levels
for this. The above illustration shows the values used. The black
triangle representing the lightness of black tones was dragged to the
right, increasing the saturation of black areas. On the other hand,
the grey triangle representing midtones was moved towards the left, in
order to give some brightness to the whole photo.

Blue transition
Masked areas
Green transition
After
all these preparations, we started to color the photo. We had a pretty
easy job to do, as the two main color had to be the green of the grass
and the foliage at the bottom and the blue of the sky above. The
simplest method was to create a Gradient transition layer on the Layers palette. The red arrow at the bottom shows the icon for the menu containing the Gradient
command. On the appearing dialog, we first created a transition from
grass green to no color, which we then copied onto the photo using the Gradient Tool (press G).
This way, the lower part of the image got a green surface with an
upward decreasing intensity. The blending mode of the layers has been
set to Color from Normal, so that the
green color infuses the previously grey areas. As certain areas—such
as the smoke and flames of the rocket—that shouldn’t have done so got
green as well, we clicked the layer mask image displayed on the right
side of the transition layer, and used a simple brush to mask out all
areas that didn’t need any green. Using a lower opacity value in the menu on the top enables you to clear all the unwanted verdancy much more finely.
The coloring of sky required us to repeat the above procedure. This time, we used the Gradient
tool to apply a transition from sky blue to no color, stretching from
the top of the picture to the middle. As the blue color fills the
upper regions of the photo rather homogeneously, we didn’t need to do
any masking in this step.

Deeper blue transition
Deeper green transition
Because
of the phenomenon called aerial perspective, objects in the foreground
always sport a more vivid color. In an attempt to mimic this effect,
we repeated the two above steps again. Now we chose a green transition
with a slightly more yellowish, vivid hue and applied it to the lower fifth of
the image to provide a livelier coloration to the plants in the
foreground. The depth of the sky was enhanced with a deeper blue
transition on the upper fourth of the photo. This made the color of the sky more realistic.
The blending mode for the sky’s layer was Hard Light instead of Color this time to emphasize the effect. You can also use the Hard Light blending mode for the new green transition, but you can simply leave it on Color as well.

The final stage of coloring was to apply colors to the smaller objects in the picture.
We
chose arbitrary colors for them, guessing for the probable original
ones. We applied them with a smaller soft brush. You should use a
different layer for each color. This is how we applied the imaginary
purple of the flowers in the foreground, the greyish blue of smoke, the
greenish blue of the remote hills and the reds and yellows of the
flames. There are no all-round instructions for this stage. You only
need a bit of dexterity and some imagination. The more fine color layers
you apply, the more realistic effect you can achieve. Obviously, we
cannot spend a week detailing it in this article, so we painted only the
more important elements. Use the Color blending mode for the layers.

Finally,
we conjured a few wisps of clouds upon the sky. We used a white color
gradient for this, similar to those discussed above. Then, just like
with the first green layer, we switched to the mask layer and used Filter/Render/Clouds
to produce clouds. As the colors now covered the whole of the picture,
we used a large soft brush to remove them from the landscape and the
other areas where they were unwanted, and decreased Opacity to make the remaining ones look softer.
This is the time for reducing size, too. Click Image/Image Size.

In the very end, a bit of Auto Contrast (Image/Adjustments/Auto Contrast) and saturation increase (Image/Adjustments/Hue Saturation) helped the picture to look even better. You can also try to apply some sharpening (Filter/Sharpen/Unsharp Mask) to the reduced image, and you are done.
