Edit 1: Colour splash
For this edit, I decided to do a colour splash with this image. I chose this image because to had many vibrant colours to choose from. the yellow boat stood out to me as it was slightly out of the group of boats and also the most noticeable colour. I first went to saturation of individual colours and turned all saturation down to 0 for each colour apart from yellow. This then left me with the image on the second screen grab above where I had the yellow boat visible but also many other yellow parts in the image were also visible and not in black and white. I then clicked the brush tool, circled in the top right, and turned the saturation down for the brush. I simply needed to brush over the rest of the image around the yellow boat so that the image was all black and white apart from the yellow boat.

Edit 2: Marquee tool experimentation
For this edit I chose a photo and decided to make it more interesting but adding a section in the centre that stood out. I used the Elliptical Marquee Tool to create the circle and clicked shift to make it a perfect circle so all I needed to do was adjust the six and the position of it. I put it in the centre of the image and then right clicked the circle and clicked layer via copy. I experimented with the shadowing and position of the circle by adding a drop shadow to create the effect that it does below. I made this shadow the whole way around the circle. I then went down to the layers on the right and made the middle section black and white and kept the background in colour to create the second image below.
High saturation edits-
For this edit I simply had to change the saturation dial on Lightroom and make it the highest possible one. As well as doing that I also went on each individual colour and upped the saturation on each to make sure I had the highest amount. This made the image look more vibrant and less dull and grey looking.
