Maybe you should consider using other Ad Networks like BuySellAds or Chitika, etc. Google Adsense is not the only ad network that you can make money out there.

Plus, to actually be accepted in Google Adsense, you need high traffic (i.e. 1000++ page views every week or every month). And when you do, you only earn a few dollars.

I can see that you make good content. Have you considered making an instructional ebook on how you make quality photos using only a mobile phone camera? You could sell that off instead.
