I edited them using my iPad app called Photoforge 2 and After effects on my computer. Mainly used Curves, vibrance, brightness and saturation and tint effects to add and change colours to suit what I want my final video to look like.
These locations had to have interesting buildings or environments around them to film. I wanted to have a great location and background to give atmosphere.
Also time of the day was important to get the perfect colour. In post production you can always change the colour tone and change time from sunny to rainy, but works better if you already got the weather or time shot exact or similar time.
