A lot of about photoshop
A sunset, especially at sea, can be an amazing color spectacle. The hues will depend heavily on the weather, though — but you can push them a bit with a gradient map. Click on the “New Fill/Adjustment Layer” button in the Layer palette and select “Gradient Map” from the list. Click on the gradient to open the “Gradient Editor.”

Gradient Map
Click on the first color patch below the gradient, and change the color to red. Set the color patch on the opposite side to yellow, and click “OK.” Set the blending mode to “Soft Light” and reduce the opacity to about 50%. This will create a warm, almost golden sunset.

Observe the movement from a blue to a golden sunset.
Creating Smiles
Roughly
select the area around the mouth with the Polygon Lasso tool. Go to
Select → Modify → Feather, and enter a radius of 10 pixels. Confirm,
then click on Layer → New → Layer via Copy (or press Control/Command + J), then Edit → Puppet Warp. Photoshop will put a mesh over the entire layer in the shape of your previous selection.

Here’s the mesh over the layer.
You
can control the size of the mesh with the “Expansion” value in the
Options bar. Increase the density to “More Points” for increased
precision. Press Control/Command + H to hide the mesh, then
set the first pins to the corners of the mouth. Add more pins to
distinctive spots of the mouth. By clicking and dragging the mesh, you
can shape a nice smile.
Colorful Water Drops
Macro
shots of water drops are appealing, and shapes can be further
accentuated with discreet coloring. You could treat the bland surface
with a linear gradient from #772222 (RGB 119, 34, 34) to #3333bb
(RGB 51, 51, 187). If the photo is on a layer of its own, click on
Layer → Layer Style → Gradient Overlay or double-click the layer next to
its name.

Layer Style: Gradient Overlay
Set the blend mode to Color, the opacity to 50%, the gradient to “Foreground to background color” and the angle to 90%. The gradient will be saved as a layer style, so you can come back at any time to adjust the values. Double-clicking the style name opens up the dialog window once more.

Skin Color
If
the skin is not quite perfect after retouching, it might be because of
the general hue. You can control it by going to New Adjustment Layer →
Hue/Saturation. Click on the miniature mask, and press Control/Command + I to invert the mask.

Adjustment Layer: Hue/Saturation
Using white color and a soft brush, paint over the skin areas so that only they get treated. For the adjustment, switch from Standard to “Reds” (found in the Hue drop-down menu of the Adjustment layer), and use the Hue, Saturation and Lightness sliders to adjust the skin color. Switch to “Yellows” and optimize the skin tone. Getting the colors exactly right depends very much on the image material. Rely on your common sense.

Optimized skin tones
Matching Skin Tones
A sunburn or a blush can disrupt a portrait, especially if there is a contrasting pale person nearby. Photoshop has a tool to correct that: “Match Color” offers control over skin tones. Open your image and use the Quick Selection tool to roughly select the red skin areas.
You can hold down the Alt/Option key and subtract areas from the selection. Click on Select → Modify → Feather and enter a value of about 15 pixels. Use the Control/Command + J shortcut to copy the selection to a new layer.

Adjustments: Match Color
Using the same technique, copy the non-reddened skin to a new layer. In the next step, you’ll have to differentiate between the source layer and the layer to edit, so rename these two layers meaningfully; all it takes is a double-click on the layer name. You could use the naming scheme shown here and call them “Beautiful skin” and “Reddened skin.”
Activate the layer with the red skin, and select Image → Adjustments → Match Color from the menu. For “Source,” select the current document, and for “Layer,” select the one with the beautiful skin. Control the effect using the “Luminance” and “Color Intensity” sliders in the Image Options area. Once you confirm, you can control the effect’s strength with the Opacity slider.

Reducing Noise
Noisy images are annoying. One way to reduce noise is through the channels. Copy the background layer by pressing Control/Command + J,
switch to the Channels palette, and select the channel that shows the
least noise. Drag that channel down to the “New Channel” icon (next to
the trash can) and go to Stylize → Find Edges. Then apply a Gaussian
Blur with a radius of about 3 pixels.

Look at this copy of the red channel.
Click on the new channel’s miniature icon while holding the Control/Command key to select the content. Activate the “RGB channel” (top-most), and switch back to the Layers palette. When the duplicated background is selected, click on the “Add Layer Mask” icon.
Click on the Layer Miniature icon, and select Filter → Blur → Surface Blur from the menu. Play around with the Radius and Threshold sliders until the noise has been reduced as much as possible. Thanks to the mask you created, the contours are safe.

With and without noise
Retro Look With Curves
Go to Layer → New Adjustment Layer → Curves and switch from RGB to Reds. Then drag the line downwards a little for the shadows and upwards for the highlights, creating a slight “S” curve. Do the same for the Greens. For the Blues, drag the highlights down a little and the shadows up (for an inverted S shape). The shadows should now be slightly blue-ish, the highlights slightly yellow-ish.

Adjustment Layer: Curves
Create a new layer with Shift + Control/Command + N, and fill it with #000066 (RGB 0, 0, 102). Set the blending mode to “Exclusion.” Now copy the background layer by clicking it and pressing Control/Command + J. Set the blending mode for this copy to “Soft Light.”
To
decrease the effect overall, activate the top-most layer and then click
on the background copy while holding the Shift key, thereby selecting
both layers. Alternatively, you can add them to a group with Control/Command + G.
Reduce the layer’s (or group’s) opacity. Note that in Photoshop
versions prior to CS5, you’ll have to reduce the opacity for each layer
individually.

Achieve a simple retro look in a few steps.
Identifying Layers
If you’re ambitious with your collages, then you’ll be familiar with this problem: meaningful layer names are often neglected during the creative process. This can result in layer names like “Layer 4” and “Layer 5 Copy 2,” which are not very helpful when you need to quickly identify the contents of a layer.
Photoshop offers a number of solutions for our laziness. For example, you can click on the element you want to select by using the “Move tool” and holding the right mouse key; you’ll see which layer contents are below the tool. Photoshop will display a list in a drop-down menu, from which you can easily select the desired element.

Right click with the Move tool
Control/Command + left-click
with the Move tool selected and, in most cases, you’ll select the
corresponding layer of the element that your mouse is over (unless
Photoshop can’t distinguish between the multiple layers).
You could also Control/Command + left-click
on a layer’s miniature icon to get a selection of the content of that
layer. The marching ants will show you what is on that layer and where
it is.
Another option is to click on the Layer palette’s Options icon, in the top-right corner, and select “Layers Palette Options.” From here you can adjust the size of the layer’s miniature preview and concentrate the miniature’s content to the layer’s bounds, which should cut down on future guesswork when it comes to layer contents.

Conserving Resources
Plug-ins save time, but they’re a bit resource-hungry; at least, they lengthen Photoshop’s start-up time. Your plug-ins might have functionality that you rarely use, so deactivate them until you need them. To do so, create a new folder by going to Adobe → Adobe Photoshop CS5 (or whatever your version) and name it something like Plugins_deactivated.

After disabling some plug-ins.
Now move all of the extensions that you don’t need for the moment. When you restart Photoshop now, those plug-ins won’t load, so the program will start up quickly. Your RAM will be relieved. Because you neither deleted nor uninstalled the plug-ins, they’re available to use anytime. If you need them, just move them back to the plug-in folder.
Classy Sepia Look
The sepia look is an absolute classic. To enhance a black and white image with a classy sepia tone, follow these steps. Click on Layer → New Adjustment Layer → Photo Filter, and select the Sepia filter, with a density of 100%. Double-click the layer (not the layer name) to open up the Layer Style window. This will show the Blending options.

At the bottom of the dialog box for the first gradient, move the white slider to the left while holding the Alt/Option key. This creates a smooth transition between adjusted and unadjusted areas. The sepia will now look elegant.

Precise Positioning
I’m
sure you’ve often been irritated by Photoshop’s tendency to position
elements on its own, but the program is just trying to help you align an
element that is on its own layer with the outer edge of the document or
with the edge of another object. To your frustration, the layer’s
content will jump to the edge, even though you wanted to leave a few
pixels of space in between. You can temporarily deactivate the automatic
snapping by holding the Control/Command key as you position.

Applying Layer Styles Multiple Times
Usually, layer styles can be applied only once. For example, if you click on Layer → Layer Style → Drop Shadow, you cannot create a double drop shadow, one of which has an angle of 120°, a distance of 2 pixels and a size of 2 pixels, and the other of which has an angle of 180°, a distance of 12 pixels and a size of 12 pixels.
Actually, it is possible! It just requires a little detour. Create the first drop shadow as you normally would. Then right-click on the layer and select “Convert to Smart Object” from the menu. This smart object can be assigned another drop shadow, and you can convert the smart object into yet another smart object. This way, you can easily add a third and fourth drop shadow. Alternatively, you could apply multiple strokes.

Three shadows in combination.
By the way, to put one or even several styles onto their own layers at once, right-click on the FX symbol and select “Create Layer” from the list. Now you can apply filters to these styles, but they won’t be editable anymore.
