Correcting the perspective

1. Capturing the images:

• Take a picture of the building, scan it and save it as .tiff or .jpg or
• If you download it from the internet it will most likely be of a .jpg format
• Take a video and capture a frame with the image of the building.

• Open the image in photoshop.

2. Editing the Image

• Select to select the part of the image you need.
• Use the Image->Effects->Distort menu item.

• 
• Correct the perspective so it looks straight ahead.
• Clip the area of interest.

• Delete or cover annoying information such as tree branches, wires, etc. This is done my selecting the area to cover copying and pasting the selected area (Edit-> Copy and Edit->Paste) and then mirroring (Edit->Transform->Flip Horizontal)
• 
• Copying and pasting will automatically create new layers:

In order to save as a simple image you need to flatten the layers into one using the command (Layer->Flatten Image)

When done, save the image as .png or any other format that is useful for export/import to another program.

Notice that out of the many different formats

• Tiff is the largest size and most accurate (good for prototype archiving)
• Jpeg, gif and png are the smallest and with a decent accuracy (good for implementation)
