In this tutorial I will show you how you can change the environment of a picture.
STEP 1.
After you decided on the picture you want to modify the background, and you decided what you want to keep and what to throw away, go to Filter and select Extract(Alt+Ctrl+X) then select Edge Highlighter Tool(B), mark the Smart Highlighting box from the Tool Options on your right and start to select the objects you want to keep. In this case the building.

STEP 2.
Press the Fill Tool(G) and click inside the selection. If it turns blue it means you have a close selection, if not then it means you have a gap somewhere in the selection. After filling the selection the press ok.

STEP 3.
Using History Brush Tool(Y) repair any edges that have not come out really great. Then you can select all picture, then press the Wand button (W), make sure the subtract from selection option is selected then press on the white part of the picture, thus living you just with the buiding selected. Copy it and put it in the new environment picture. But i did the oposite and brought the environment over the building picture.

In this tutorial i will show you how you can change faces, or just adjust a picture into another picture without deleting anything. I will make a dog wear an uniform.
STEP 1.
Open both pictures, the picture with the uniform and the pet you want to use. Drag the picture of the pet over the one with the uniform and adjust the dimensions to match the dimension of the head of the officer.

STEP 2.
Now from Layer, add a Layer Mask- Reveal All and put your colors to defalt(back and white). Remember that black covers the picture in which you are working in the layer mask and white reveals it. So, being in the Layer mask use a hard/soft brush to hide the parts of the picture you don’t want to see using black and to bring up the elements from the background picture using the white.

1. Create a new document. Choose the Elliptical Marquee Tool and make a circle, then fill the selection with the color you want.

2. Then, choose a darker shade and paint the area where light doesn’t reach. Be sure to keep your selection.

3. Now choose a lighter shade, and then the highlight.

4. Finally, use the Healing Brush Tool to blend the shades together and make the image look smooth.

1. Open a photo of an eye.

2. Choose the Magnetic Lasso Tool and select Around the eye. Then right-click on your selection and choose Feather. By feathering you will keep the color from flooding over the sides of the selection. If you have a high resolution photo, set the value somewhere around 10. If not, set a smaller value.

3. After you feathered the selection, you go on to the final part which is changing the color. You can either go to Image -> Adjustments -> Color balance or Hue/Saturation. Move the bars until you’re happy with the result, click OK, and it’s finished.

While colorizing black and white photos is a very interesting (and pretty hard to acomplish the right way) task, converting images from color to black and white is not something hard, and this feature has been around for ages in Photoshop. The only interesting thing is that Photoshop CS3 comes with a new tool that will help us with this task, and today we’ll give it a spin…
