I like it mate it's definitely going in the right direction, a few tips:
1) Definitely look at an English spell checker as there are LOTS of typos and spelling mistakes.
2) Don't limit yourself to one post a day, try for a couple or even more if you can find decent material to write and interesting subjects to write about. Google loves regularly updated sites and it will encourage the spiders to visit more regularly if you do several posts a day.
3) Take a good look around at some affiliate marketing companies, I am sure there must be some photo related companies using this method of promotion (I will try and research some later for you if I find time), you could then link direct to a website with your affiliate link in it to say the Spyder calibration tool, any sales would earn you a commission - which is a MUCH better way of earning a subsidiary income than asking people to click links
4) Enjoy it, if you really enjoy the subject you are writing about that will come across in your writing style and this will keep people coming back for more.
And lastly see if you can add an RSS feed in Blogger (I am not sure if this is possible as I have always hosted my own blogs in the past), this will allow people to use an RSS News Reader to be notified every time you make an update.
Hope these help mate, if I think of anything else I will either PM you or write it up here.
