Digital Photography Online

Of course you realize that for the digital camera you do not need a monochrome filter. How many color paper sheets, as we said above, you will find, so many you have free color filters. This is one of the advantages of digital cameras to film. Moreover, manufacturers themselves claim of digital photography: the difference between the application enhances the filter series 80 when shooting indoors with a white balance preset in the daylight and without the filter and the filter with the white balance on the filament lamps, will be only in shades. If you need to take pictures in a room set the tone light, it is recommended to set the white balance manually (the usual way to the white paper) and color filter are not to be setup on the camera lens, but on the outbreak.

A particular conversation will be about the infrared filter, RED-25 or R2. Interestingly, when color photos are taken with this filter, especially withdrawn in the matrix, rather than a special infra-red black and white film (Kodak HIE, for example). Everyone knows the inability of black and white materials «distinguish» red hues. How to distinguish between the matrixes, you can see in the end photos.
I take the pictures using the following method: set the white balance manually when keeper filter Sunpack RED-25, leads to a white surface (paper). With this balance, I dropped a shot that left the same filter. I got the right shot without any filter, and automatic white balance. The image was almost black and white. Council to do a similar experiment with a green filter.

Another advantage of manual white balance is the ability to remove extraneous modulation in mono filters. What do I mean? There are filters that do not change the overall tone of the frame, can change the selected color. These filters include polarizers L-PL, C-PL, polarizers separate colors Intensifier, Redhancer, Greenhancer, Bluehancer, PolaBlue, PolaYellow, PolaRed two polarizers and color Varicolor Blue / Yellow, Pink / Red, Red / Green, Green / Lime. I would like to include in the list and a neutral filter ND, which weakens the illumination is not changing colors. Unfortunately, these filters have often extraneous residual shade, which can spoil a picture.

Let’s look at the picture. This landscape shot by a digital camera. When using the filter Cokin 173 (Varicolor Blue / Yellow), which in turn changes the color reflections from yellow to blue, the tone of the filter residue (pink) are the clouds and grass, with a well-marked, that the color tone of the residual does not depend on the angle of rotation filter . Get rid of this unpleasant effect, you can set the filter on the lens, and then manually set the white balance. This method is suitable for all the above filters. Moreover, in this photo you can see the so-called «digital sky», ie PERESVET, milky-white sky. This is the result of non-neutral gray shadowing (gradient) filters. (About these and other filters will be discussed in the next issue of the blog.)

Since we are talking about polarizing filters, mention another advantage of most amateur digital cameras (non SLR): You can use it all, even a linear polarizer, and if the chamber has no mirrors, a linear polarizer auto focus does not put the system into confusion. Speaking of benefits, I compare the digital and film cameras around the same price category. When shooting with the use of polarizing filters, you do not need to introduce amendments to the exposition, since exposure meter is done through the lens - the camera will take into account all the amendments themselves. In conclusion, the digital photography not only allows you to fully realize your ideas with the help of conventional filters, but also provides an additional, unique ability. Use them - and you will be creativity tuned up with new colors.
