P.S. You can MIX filters to get different results... so buying 7 filters lead to more than 7 different results... for example... a warm filter with a diffuser is indicated to shot nudes with a really soft and dreamy tone... a warm filter and a skylight gives wonderful results in shoot beach scenes and boost the colors of the sand in the desert.... a Sunset filter + Diffuser could be in handy to shot a particoularly melanchonic cityscape It's a good technique to mix the B/W filters with polarizer or skylight in B/W film of even on color one. leads to nice results. ..:: Loki ::..
