From time to time I have a thought about getting a tattoo. It is a serious decision for the whole life. Before I make it - I’ll see how would I look with the chosen pattern. It is my advice for you too.
When moving the cursor above the image on the left - the image before the processing appears.
Please read precisely the description of the consecutive actions. Often there are a lot of questions in comments which are answered in tutorial content. While working with Photoshop - rush is not recommended.
1. Open the Photoshop program.
2. Open the photo purposed to processing: File » Open or press Ctrl + O keys.
...or by double clicking the left mouse button on the dark grey application background.
I’ll tattoo this pretty lady born under the Scorpio sign.
It is good to have picture of tattoo on the white uniform background - it is much easier to cut it off then. Tattoo saloons have electronic versions of their patterns - they will upload it to your pendrive for sure if you tell them why you need it and if you promise to return to them:)
Ok. We have two pictures. Time to cut the tattoo off the white background. Hide your scissors. We’ll use Photoshop :)
3. We are processing the photo with the tattoo - it must be active - click on it with the mouse once (status bar above the picture will be distinctly blue - it means that we are processing it currently).
Choose: Select » Color Range from the program menu. The following window appears:
Because the tattoo background is white and tattoo itself is nearly black - set the slider Fuzziness to the right maximum. Move the cursor above the tattoo background (it turns into a pipette) and click the left mouse button.
The program selects all the background - everything that is white, it means everything except from the tattoo. On the preview under the slider - everything what is white is selected. Click OK in the Color Range window.
Everything seems to be alright but our goal is to select the scorpion not the background. No worries. Choose: Select » Inverse from the program menu or press Ctrl + Shift + I keys. And the scorpion is selected. We only inverted the selection. What was selected - is not any more, what wasn’t, now is.
It can be seen in the following pictures (before and after the operation):
The scorpion is ready to removal.
4. Now we have to copy the selected object (the scorpion) to the cache memory. We won’t be playing games with the menus. Just press: Ctrl + C keys (Copy). We’ve got it in the clipboard.
Now click the photo to which you want the scorpion to be moved (so it is active)… and press : Ctrl + V keys (Paste). Good advice - learn these shortcuts by heart.
My word - the scorpion jumped on the lady! As you see - the program pasted the scorpion to the image (to the new layer - it always does like this - you can see it in the layer panel). Right on, but we don’t want it to look like the it wants to eat her but to decorate her arm.
In any case - we have to move the animal.
5. To move it choose the Move Tool 
from the toolbox (V)
Use it to grab the scorpion and drag it to the destination place - on the arm. For the purpose of precise localization of the animal you can use the keyboard arrows (with Shift key pressed objects move faster).
OK, scorpion is located. Now we have to rotate it so it has a nice place on the nice arm.
Choose: Edit » Transform » Rotate from program menu
Around the scorpion appears a rectangle with small squares in its corners. Locate the cursor outside the rectangle outline (it will turn into curved two-headed arrow).
Press the mouse button and rotate the scorpion by moving the mouse in the requested direction.
When everything’s good - press Enter.
If there’s a need to reduce a tattoo (I don’t recommend enlarging - big loss of quality) choose: Edit » Transform » Scale from program menu. grab an angular square, press Shift (to preserve proportions), hold the mouse button and move the cursor inwards. Enter.
Really beautiful… OK, almost.
On a skin, we have places that are illuminated less, illuminated more and we have shadows. Scorpion falls within the laws of physics too and it should be lighter where the skin is lightsome and darker where it is unlit.
Go to the layer panel. In the unfolding list (on the left side above the layers) - choose mixing: Linear Burn. Click it.
The scorpion has more natural appearance now. It looks like it is changing under the various light conditions.
If you think that tattoo is too distinct we can soften it a little (by adjusting a transparency level). For that purpose move the slider of Opacity value to the left. It can be found in the layer panel too - at the upper right. Picture below:
And that’s it. Final effect on the following picture (move the cursor above the photo):
