Hi, um, I really need to know what the following mean in terms of writing about photographs (in partcular, David Hockneys joiners of the 1980s) composition, subject matter, use of light and dark, and texture. Please email me at firstname.lastname@example.org (theres no 'u' in the naughty). Make sure you write photo help or something in the subjects so I know your not a stalker. Pleeeease, please, please help me!!
