Kenneth O'holloran documented fairs in Ireland he saw the events as rather than just trade, they are very social and cultural and bring a lot of people together for a 800 year plus tradition. The images below are from Muff fair, County Cavan.
I think this work really looks into the cultural aspect of the fair, O'holloran has captured images of people wearing brightly coloured clothes which are not typically everyday wear, this can emphasise the fact that this day is very important for them and they want to be acknowledged but on the other hand none of them are smiling and seems like they don't want a picture to be taken this is called 'Dead pan' meaning no emotion.
all the images seem to have been captured using just available light but the subject has been positioned very carefully, not many shadows on face, exposed for skin tone. A low F/stop has been used to achieve this effect allowing for more light and also creating a shallow depth of field meaning the subject has been isolated from the background.
