These are some of the photos I've taken in the past. The first photo was taken in India in 2014 using an iPad 2. For the first picture I haven't added any effects whereas for the second picture I added a filter and changed the contrast. For the last picture I took it with a iPhone 5s in 2016 (USA). I haven't made any changes in the last picture but it is visible of changes that can be seen in the picture. There is a wide array of colors in the last picture and it clearly visible compared to the 2014 pictures.
