They are VERY easy to install and even easier to use (using either action set or a layered .PSD template file). Instructions are provided. This Action Set of 9 “Seasons” and “Astronomical Dates” is not just for landscape and nature – actually it performs great on portraits and emotional scenes. That’s why it’s one of the “must have” for Wedding, Family, Seniors, Fashion or Product Photographers (these actions will make jewelry shots unique).
