Inspired by an image I love

A technique of which i am using from a photographer is Mike O'Meally which is portraits of people who have recently participated in something and are sweaty. In my case i am using skateboarding and capture the moment when they have finished. i will also be using a black and white filter as it makes the photo a lot more grittier and you are able to see all the different marks and lines and sweat on the subjects face.
My settings for this will differ as i wont be taking the photos all in one day and at the same time but instead over a period of so many days. I will be taking the photo and then converting it to black and white due to the fact my cannon camera does not have the option to produce the filter within it. For the photo in particular i took in the late afternoon and my setting were as follows - my shutter was low at around 1/25, my apeture was 6.3 but it will low for most of them between 5 and 8. And finally my ISO was set at 100.
