Edit Camera Slider Font Size

I purchased a theme from Theme Forest that uses the Camera Slider. I would like to increase the size of the font for the “Description Text”.

My site can be seen at https://appraisalforensicsinc.com/

I cannot find the CSS file that is used to modify the description text. Can you point me in the right direction please?
