1. You'd better remove the IR-blocking filters in front of CCD or CMOS sensor when using IR filters
2. Setting the white balance
3. If you don't want to do any transformation on your device, you can do some post processing after shooting to achieve the IR effect.
In which ways the infrared filter will be used?
1.Archaeology, Military,Police,Medical science,and detective work. Infrared filter allow normally invisible stains and modified items visible.
2.Plant vegetation & Landscape photography. It looks dramatically different when photographed in Infrared.
3.Photographic special effects.Infrared filters give the still and video photographer expressive and unusual effects.
In what suitable light source should I use the infrared filters?
IR filter can block all visible light under related wavelengths and very sensitive to utraviolet rays.
590nm, 600nm and 630nm for Infrared change machine. The rich colors, custom white balance, the original film in general the sky was bright red, partial brown or amber, plant leaves, blue, sky blue saturation after post-processing, the leaves yellow or golden yellow.
680nm for indoor and weak Shadows use.
750nm for indoor and weak light use.
760nm for cloudy outdoor at nightfall and brightness indoor.

I used mine with my full spectrum camera and achieved a range of effects by turning the filter and thereby increasing or decreasing the range of wavelengths that were able to hit the sensor. So much more convenient that carrying a series of different filters of different strengths. Sometimes sharpness and chromatic aberration were an issue, particularly at the 750 nm end, but that probably says more about my camera and the nature of infrared light on a camera that was designed for the visible spectrum only, and could be dealt with in editing. It enables you to get decent results whilst travelling light.

J'ai testé ce filtre en fessant des raw, et ceux filtre n'ai absolument pas un filtre infrarouge, c'est un filtre rouge assez bas de gamme, prix maximum conseiller 5€

Das Öl lässt sich nicht säubern sehr klebrig!Lebensdauer steht nich im Verhältnis zum Preis.

It's really cool for focusing before you shoot. I just dial down the IR and auto focus works!Then I dial it back up to desired setting and start taking test exposures for calculating exposure and WB.

This product is composed of two thin glass polarizing filters with polarization extinguishing from red to mid near-infrared. The rotating dial causes them to be aligned in their polarization axis or anti aligned at 90 degrees. When anti aligned, and very dark to the eye, only the deep portion of the near infrared that is greater than 750nm will transmit through the filter. This will often give more of a black and white deep contrast infrared photo. When aligned, and red to the eye, you will get a much more red filter with color transmission photo that has pale blue foliage and brownish skies.At some rotation angles, I noticed optical distortions in the polarizing extinction. This gives rise to nonuniformity in the image. This is why I dropped a star.In general, it's a great concept, but using lower quality optics. Perhaps my copy has defects. I would pay twice the price for a high quality version. I would also be willing to test out copies more rigorously if the seller would like, including spectral transmission curves.My copy was labeled as Fotga brand, with 77mm threads and ~85mm glass.

lo he probado esta tarde y muy decepcionado con el producto,y por lo que acabo de leer no soy el primero al que le pasa esto.no es que sea un filtro de los mejores pero de dar unos resultados pasables por el precio que tiene...a que las fotos salgan con esas horribles manchas regules como lo regules hay un paso abismalno deberían vender este producto con estos defectos tan graves y mas siendo en fotografia, obviamente lo voy a devolver ahora mismo

Eine variable Wellenlänge bei diesem Preis hätte Warnung genug sein müssen. Die Neugier hatte dann doch überwogen und um es kurz zu machen: Die optische Leistung ist mangelhaft. Einen optisch adäquaten Filter kann man in dieser Konstruktionsmethode nicht bauen. Durch die minderwertigen Komponenten kommt es erwartbar, wie schon bei anderen Rezensenten, zu der ausgeprägten X-Bildung im Bild. Die Schärfe durch das Glas ist mangelhaft, die Filterfolien mangelhaft und die produzierten Fotos nicht verwendbar.In der Vergangenheit konnte ich mit einem B+W-Filter testen, der das 6-fache gekostet hat. Der hatte brauchbare Bilder gemacht.Der hier angebotene Filter ist schlichtweg sogar zum experimentieren zu schlecht, weil die optische Leistung jenseits von gut und böse ist.
