Im getting dust spots on my photos i have a dslr, and i put it on bulb and just blew some air in there, also whats a good way to clean lenses? Is there a way to make your own lens hood? i was thinking of using pvc pipe, and spray painting it black.. Im going on vacation in a day to the poconos and i really want to get some good pictures of waterfalls nature. i have some filters but not sure what to use them for, i have a polarizer and a UV.. would these help me at all? do i need to use them if i have a lens hood? thanks

If or after the lens is clean, cover it with a clean UV filter and leave the filter on the lens until you need to use your polarizing filter.

Polarizing filters are used to produce deep blue skies and amazing cloud exposures. This works the best when your camera is aimed at 90 degrees to the arc of the sun. When you look through the lens, adjust the filter until the sky looks the best to you. It is also good for removing reflections in reflective surfaces like still ponds, windows and other shinny surfaces.

Unless you are shooting toward the sun or other light source and your lens or filter is especially dirty, lens flare will be held to a minimum. There are times you can use lens flare as an artistic tool. Try that while shooting landscapes with your lens at its smallest focal length.
 
Well, to some extent, you can use your hand as a lens hood, all the lens hood does is prevent 'flare' from the sun shining directly into your lens, though it is also handy in the rain to keep spots off the front element.

A polarizing filter reduces nonmetallicc glare, it eliminates the reflections of light from rocks and leaves, and other non-metal objects.

A UV filter cuts throught the Ultra-Violet rays in photos, it can get rid if a lot of the haze in distant scenery
