Yes is true! Not every day is a good day to stock image.
On sunday i make a visit to a small lost village in the heart off Portugal, the oldest in the country with more that 600 years. You can see some pictures in this site here. At the beginning i was very happy with this trip, was a chance to take great pictures, maybe some of them can be stock pictures. But like i find out, some days are not pictures days.
I don´t know what was wrong with me, every picture that i take in that day i look at and think "my god this is really crap!".
In the end of the day and after i made 500Km i realized that is not the equipment that matters, but the person behind!
Remember, don´t make long trips to take pictures if you don´t feel good inside!
