For these images I experimented on I used the same technique for them all. I started off by using the magnetic lasso tool on photoshop and outlining the section I wanted to put a filter on. after I outlined the section I selected the filter I wanted. For this I used a variety of different ones I used ‘Strong’ which is a black and white filter for all my black and white images as I found it was the most prominent and I liked how strong the blacks and whites were. I used ‘Blue Mood’ for a blue-purple sky, and ‘Split Tone’ for the yellow-green sky.
