Tip: don't be afraid of high ISO

Example of using high ISO

You know that very saying that you should always shoot at your camera lowest ISO (eg. ISO 100 or ISO 200), don't you? Especially when doing HDR photography. It's a good thing in general as it results in the best image quality.

Sometimes, however, it's virtually impossible to do that because there is no way to set up a tripod (in case of the above photo there were some metal bars making it really difficult) to get fast enough shutter speeds. So should you just miss that very shot? No. In such cases don't be afraid to use higher ISO values. In the image above I used ISO 3200 and the image is still clear and sharp (in the past I even used ISO 6400 and I was still happy with the output). It also didn't require that much noise reduction as you might think. Modern cameras have very advanced sensors which really make high ISOs usable. Try them - they might be a life saver one day.
