Once again, we're only working with an image and the title. Fortunately, there is text in this one. It's still not clear, but it's a start. It goes like this:
'O fuge Iabrochium, sanguis meus! Ille recurvis
Unguibus, estque avidis dentibus ille minax.'
It's a fragment from one of several Latin translations of The Jabberworky by Lewis Carroll. It is only loosely connected to the answer.
To solve this one, you need a good monitor and a specific calibration. Lower your contrast, or if you have an LCD screen, look at it from an angle. Otherwise, you can NOT solve this one (unless you get really, really lucky with your image manipulation.) You'll know it when you'll find it.
Photophobia means 'the fear of light'. Maybe you should not be afraid and start looking at it.
It is not a date, as there are actually 4 numbers. It does not follow the usual 1=A,2=B... pattern either. Each number does link to a letter though.
