to day we were told how to fix up pictures so we could apply a texture.
in order to test if a building is strait the guide lines are very usefull.
after putting the guide lines on the picture , lining up the lines to the windows ect.
then use skew to straighten it up. after that you can use the patch tool, spot healing brush or select an area and use fill, contence aware. this will get rid of the parts of the picture that are unwanted.
after i did this i was told i should experiment more with the tools so i did and ended up taking away all the windows.
after i could have added on a texture or colour overlay to make it more interesting
