1 stop, 2 stops, 3 stops, etc. Sometimes these are referred to as EVs, for exposure value. These are probably the most convenient measurement because they tell you how many stops they'll adjust your exposure by.

Move it around in small, prey-like movements until you have your cat’s attention. Imagine a mouse running around on the floor. Sometimes it runs in a straight line, or into a corner, or back and forth. These laser pointer movements will likely catch your cat’s interest the quickest.

It’s the reason your cat stares at small bugs crawling on the floor before pouncing on them or looks longingly into the yard at the birds at the birdfeeder. It is also the reason your outdoor cat may occasionally bring you “presents,” such as birds, lizards, or even small bunnies to leave on your doormat.

One question you probably have is why and in what situations would you want to reduce the amount of light coming into your camera sensor.

Don’t use the laser in a way that overworks your cat or allows them to hurt themselves. For example, if your cat is usually a couch potato, try starting slow.

Each cat should have their own laser pointer light to chase, and the lights should be moving in opposite directions. Until the cats know each other well, refrain from having them play together with the same light.

Cats can have different degrees of prey drive. Many cats will chase the laser pointer at a high pace for several minutes. Some cats need more encouragement than others. If your cat does not seem interested or loses interest quickly, using the laser pointer in conjunction with catnip for a bit more excitement may help.

With laser pointers and any other chasing-type toys, you should let your cat catch them occasionally. This is important for several reasons, including building confidence. No one likes to play a game they can never win, and the same goes for your cat. Also, for more sedentary cats, they will likely lose interest quicker if they don’t catch the light.

There are many types of lasers on the market—even some that are automated so your kitty can play when you are not at home.

After your cat catches the light, let them study it for a little while, then slowly start moving it away as though the “prey” is escaping. The race will soon be on again.

Again if you’re trying to go with a very very wide aperture on a sunny day well cameras have sync speed limits which means you cannot really use super-fast shutter speed and so one of the best ways to manage that is to lower the amount of light coming in-camera through an ND filter.

2x, 4x, 8x, etc. Sometimes these are referred to as ND2, ND4, ND8, and so on. These refer to the amount by which the light is diminished. An ND2 filter halves the light, while an ND8 filter reduces it to one-eighth.

For example, the long exposure shots like if you’re shooting a river or a stream or waterfall and you want to get that misty look. An ND filter is a spectacular way to go. However, it might be confusing in terms of the grade of ND filter you have. You have to know how dark it will get and the problem is these nomenclatures are used interchangeably so let’s just dive into the chart.

The ND filter is a filter that, placed before the lens reduces the amount of light reaching the camera's sensor. It acts like a pair of sunglasses to your lens.

A stop is an arbitrary amount of light. If you have a shutter speed that’s twice as long as one before. You’re letting in twice the amount of light that is one stop. ND filters are rated in the amount of light that they reduce coming into the lens. so if we say this is an ND filter with the one-stop intensity that means it would let in half the amount of light as it did before and this is how ND filters are rated. So they have different intensities from 1-9 or 10,000?

ND filters come in different strengths or darkness levels. For the photographer, the easiest way is to have ND filters that tell you how many stops of light they will darken your exposure. Most brands of ND filters label the ND filters with either a factor number or optical density number. But for the photographer, neither of them is referred to the number of stops by which the light is reduced.

So if you have an ND filter with strength or intensity of 2 all you need to do is turn it into a fraction by putting a 1 above it. So ND filter of 2 is going to let in half the amount of light. An ND filter of 4 is going to let in 1/4 amount of light and so on. So if it’s a 3 stops reduction, it will let in 1/8. if it’s a four-stop reduction so it’s an ND 16 it’s going to let in 1/16. if it’s an ND filter then reduce it by 5 stops that would be an ND 32 . and that’s going to let in a fraction of 1/32. and so on and so forth.

As pet parents, we can use our cats’ natural prey drive to help keep them mentally and physically healthy. To get your cat moving, a laser pointer can be a great tool that you can use in conjunction with a good diet.
