Yes, that is normal because that is not how this filter works. This filter is roughly equivalent to a ten-stop filter. You'll need to figure out the right exposure time; I won't go into detail about long exposure photography here, but you should start by doing some research on the subject. Here's a quick way to get started: (use a tripod if you don't have one)br>1) Change the camera's setting to M (manual). No automatic settings should be used. 2) Increase the aperture to a full stop, such as 2. 8 or 5. br>3) focus manually on a subject. br>4) attach the filter to the lens. br>5) Begin shooting and experiment with shutter speeds until you achieve the desired exposure (the final image will have a red tint). Begin with 1 to 3 items at a time. a second attempt (Bulb setting may be required). That's all there is to it.
IR is typically not well seen by Canon cameras. As a result, you must deal with long exposures and other issues. I recently purchased an Olympus E-M1 camera. The P5 and the Olympus see infrared very well; in fact, I can take a shot with it in under 2 seconds. My camera isn't equipped with a conversion kit. The lenses are the most serious problem you have. Hotspots can be found in some of them. which has the potential to detract from a person's appearance.

I'm new to infrared photography, so I can't comment on how well it compares to other options (or even a complete conversion!). ) but I can confidently state that I was able to remove it from the box, mount it on my lens, and begin taking photos similar to the ones that drew my attention and piqued my interest in infrared photography within 5 minutes. While you only have a limited amount of time- Because of the physical limitations of non-professional photography, exposure shots with this are limited. Even with the converted cameras, I get the lovely ghosty, vintage look that I've been obsessing over lately. Now, there is some post-processing required to compensate for the occasionally frustrating exposure results, but I think it's a good trade-off. I'm glad I didn't have to convert one of my camera bodies to permanent IR just to dabble in this area of digital photography! br>br>As for the product, it arrived sealed in a standard filter box. My only complaint was that the filter box had some small broken pieces of plastic rattling around inside, which worried me at first, but they were only making contact with the metal ring on the outside and were not damaging the glass or coating. The filter is a little thicker than my Kaesemann circular polarizing filter and feels a little heavier. I had the best luck focusing my Nikon D810 by removing the filter, autofocusing, then switching to manual focus and replacing the filter. Putting the camera into Live View allowed me to adjust the aim on it, but any refocusing I did required me to remove the filter for a brief period of time. If I find a subject with enough contrast, I believe the camera will be able to focus with it on (I was testing this with trees in spotty light, which was not ideal). ) There were definitely hot spots, but that's a known issue when using a regular lens for IR, not a filter flaw. The contrasts between "straight sunlight" and "cloudy sunlight" (3pm light) were enormous, necessitating a lot of shutter speed fiddling! br>br>Attached are two copies of the same photo that I took during my first test of the filter. The first is unedited and looks as it did right out of the camera, while the second is after some Lightroom tinkering.
This is an excellent infrared filter.

I won't bother because there are plenty of post-processing tips available online. The slide-in filters may be more convenient because you must compose with the filter off, then attach it before taking the photos. Repetition is required if you move to a new location. Of course, a tripod is required for 30 seconds, but the filter is light and simple to use. However, it appears that if you attach it tightly, it will be difficult to remove, so I only do so loosely. br>br>I got the largest filter diameter I own (77mm) as well as step downs for the rest of my lenses. The filter is really cool. I'm thinking about trying something with a little more visible light.
