IR filter for budget tariff - advantages and disadvantages - does not work with any camera

1. Camera has a built-IR cut filter in front of the sensor?
2. What wavelength is already filtered by the camera itself?

The reason why I had ordered this filter simply that I had tested my Pentax K-5 DSLR before (!) With a TV IR remote control and had thus found that infrared light is detected by the sensor was (the diode lit up the test photo). It is thus possible with a remote control not notice how much gets to infrared light to the sensor, and the effect will be, depending on the camera, be stronger or less strong.

The product:

The filter comes in the usual plastic box, therefore, is packed and padded feels wertig, he is on the filter thread of aluminum. The glass is very loose inside the filter and is apparently not completely screwed. In my copy I had in any case the screw-threaded ring that holds the glass in the filter, three turns (!) Tighten and for this reason I prefer from a star. If I had that would not notice the glass probably fallen out and the result would have been broken.

The function:

With 720 nanometers of the filters is very well suited to filter the visible light so that only light from the 720nm strikes the sensor. This means first of all "red Photos" and it is not the effect you might hopes from the camera immediately. You have to edit the "red photo" To get an IR photo with the typical white sheets and shifted color information.
Here there is a very easy way - is converted into black / white order and immediately the desired effect of eg white foliage. Somewhat more complicated is the conversion from the "red photo" in a color photo, here you have a bit more to take processing purchase, for example, the channels "blue" and "red" swap etc.
In general, the filter is very good for the money, if I with my little Hoya the IR720 comparisons, then the Polaroid the more expensive compared Hoya is second to none.
The article pictures I have uploaded examples - who wants to can see the effect there.
To end with the IR photography, you definitely need a tripod and a camera with the ability to expose long. For IR photography works no metering and we see almost nothing through the camera's viewfinder. Thus, one tripod incl. Camera builds on, focuses on the subject, then screwed until the filter and catches as possible to "sun at your back" with eg a diaphragm 8 and from 15 seconds up at ISO 100. Here I use always the manual mode and sensibly you shoot in raw format (RAW) to subsequently in image editor or Developer Program (RAW converter) to adjust the results.
What is definitely not working taking pictures with full automatic and Co. - IR photos are always something handmade :)

Conclusion:

Well packed with superior image quality, this filter is unbeatable in the price / performance ratio and if the a priori in itself (filter glass) would be bolted, I would smooth give 5 star - thus really only one star deduction for the "almost total loss" - and who his camera before on IR suitability test with respect to the fact built blocking filter, which should buy the part.
