photography hints and tips - filters - warmup
Friday, November 28th, 2008Almost since the discovery of photography and certainly since the early 20th century filters have been used to make changes to the look of photographs. There are hundreds of filters you can use. Some are for use with black and white only some for use with colour only and some can be used with both. Each filter has a number and in the case of warmup filters they range from 81a, 81b, 81c, 81d, to 81EF. These are generally used with colour photography when the sky is very grey and overcast and gives everything that dull grey look. Things look cold and uninviting. In the days of film a warmup filter was essential, this was put on the front of the lens, either screwed onto the front or a generic system can be used where a ring is screwed to the front of the lens and an adapter put on the ring and the filter fits in the adapter. With the adapter method several filters can be used together. In these days of digital photography it can all be done with photoshop, simply click on image->adjustments->photo filter (in CS3). This brings up a window which asks you to name the layer and choose your filter colour. You can vary the strength of the filter by adjusting the density, changing the filter itself or even picking your own colour, it’s all so versatile and done in the comfort of your own home. Below are 2 photographs one without any filters and the other has a warmup filter added to show the effect. In the second image you could almost imagine the sun had come out (it hadn’t).
