Experiment 1: Colour block
For this edit, I first had to start by picking an image that had an obvious colour in it so that I could make it stand out with the black and white. I chose this photo as yellow is a bright colour and would pop out well.
I got the photo up on Lightroom and then turned all the saturations to -100 on every colour but yellow as that was the colour of the umbrella. this washed out the colour elsewhere in the photo, however, it wasn’t completely black and white. using the brush tool I needed to scroll down and select saturation and turn it down to -100 as I did before with the individual colours. Then I could adjust the size of the brush and drag it over my image around the umbrella. The last step I did was going back to the first step to the saturation of the colours and select yellow and increase it so that the yellow became more vibrant amongst the black and white.
