What do warming filters do




















However, UV filters can still remove UV haze in specific situations. For that reason, they are sometimes referred to as haze filters. Digital cameras will only pick up this type of haze when ambient UV levels are very high. One example would be if you were shooting at a high elevation on a bright day and near large reflective surfaces like snow or a body of water. In that situation, if you tried shooting a distant subject, the UV light between the subject and your camera could result in haze in your image.

A UV filter would remove that haze. Similar to clear filters, some photographers use UV filters primarily to keep their lenses protected and clean. Check out this guide to learn more details about UV filters. What makes this filter a good option is it offers high light transmission with minimal distortion and reflections.

The Best Cameras for Landscape Photography. ND filters are made with dark-colored glass and are used to limit the amount of light entering your sensor without affecting the color of your image. They can help you avoid overexposing your images in bright light, especially when shooting with slower shutter speeds.

A good ND filter will solve that problem. But these lens filters are not just used for landscapes. These filters vary in darkness. Like any filter, the amount of light they block is commonly measured in stops. The higher the number of stops, the more the filter will darken the image.

To help you make sense of it, there are ND filter beginner guides that include conversion charts. Benro Master Series ND 3. GND filters are similar to ND filters except they transition vertically from dark to clear.

They are used by landscape photographers for shooting scenes with lots of contrast, such as a bright sky with a dark foreground. To enable adjustments to suit the scene, most of these lens filters are made in a rectangular shape so you can move them up or down depending on how high the horizon is in your composition.

Hard-Edge GND filters transition abruptly from dark to clear. They are designed for shooting scenes with a flat horizon. That way you can line up the hard edge in the middle of the filter with the horizon, so you only darken the bright sky and end up with an evenly exposed image. Soft-Edge GND filters differ because they have a smoother gradient from dark to clear. If you tried to shoot these scenes with a hard-edge GND filter, it would result in a noticeable midline where the brightness changes.

But the gradient on a soft-edge filter avoids that problem. Reverse GND filters are ideal for shooting sunsets and sunrises. As a result, they can let you capture evenly exposed images when the sun is near the horizon. Be sure to take a peek at our guide on how to photograph sunsets! Vu Filters x mm Sion Q 2. Polarizing filters can reduce reflections and glare in a scene and provide more vibrant colors.

They enable you to limit the amount of polarized light that enters your lens, depending on the direction the light is polarized in. The beauty of working with custom white balance settings and a gray card is that you can make whatever correction is needed at the time, no matter the color of light you're working with. If you accept that, and resign yourself to white balance correction after capture, you might wonder why bother with white balance settings in the camera.

Why not just make the whole correction in your imaging application? Photoshop, Lightroom, Aperture, whatever. With raw files, the white balance setting merely writes some metadata into the file; it doesn't change how the sensor captures the image.

Nevertheless, my experience is that it is easier to dial in final white balance correction if the image arrives in my imaging application close to correct to begin with.

The larger the move required to correct the white balance, the harder it is to get it exactly right. For whatever reason, my camera's ability to analyze a gray card image is outstrips my ability to make the same moves manually.

I, on the other hand, am better at making the final tweaks to white balance by eye than my camera is. I think we make a good team. If you're shooting in raw, and using the right software one that processes in high bit-depth then it's unlikely using a warm filter will produce a better photo. As long as you capture the photo as well as you can, setting the white balance on your raw files in post is going to be a much easier solution.

Now, you can accomplish this in post-processing as well, to a certain degree, by taking two shots one exposed for the sky and another exposed for the land and then combining them into a single image. But it's a lot simpler to get this right in camera with the help of a filter. One thing to be aware of when using a graduated ND is that you need a certain amount of precision to keep the edge between light and dark in the correct location.

When using a graduated ND with a soft edge, you may be able to see the transition in the finished image, especially if the division between light and dark in the scene is more abrupt than it is on the filter. And you may not get very good results at all if, for example, you have a lot of trees that start in the lighter land area of the scene and extend into the darker sky area. When you use a graduated ND with this type of scene, you may be able to see that division between light and dark on the tree trunks, which will look really unnatural.

In the past, if you wanted to change the white balance in a scene you did it with film you could get daylight or tungsten balanced film, for example or you did it with warming and cooling filters. These filters do pretty much the same thing as your camera's white balance setting does—they remove a color cast or they add one.

If your goal is to take that blue tinge out of a shady scene, for example, you would do that with a warming filter. If your goal is to make a red sunset even redder, you would also do that with a warming filter. Digital cameras have made warming and cooling filters almost obsolete, because you can warm or cool a scene simply by changing your white balance setting. If you don't get it right the first time, you can also fix it in post processing this becomes even simpler if you shot your image in RAW.

But there are still a few lighting conditions that you can't fix with your white balance setting. Underwater shots are one clear example of this—when you shoot underwater, the predominant color is blue, so blue, in fact, that your white balance setting can't correct for it. And if you try to fix it in post-processing, you may end up introducing a lot of unwanted noise. Any situation where the light is predominantly blue or predominantly red can still be improved with a warming or cooling filter, respectively.

You'll hear a lot of photographers talk about "stacking" filters, which just means screwing one filter on to another. You can achieve even more light reduction by stacking two ND filters, for example, but you shouldn't do this without being aware of the drawbacks. Stacked filters can create vignetting, or a darkening of the corners of your image. Nikon Fs 24 mm filtered reality 12 - triplets by Flickr user mugley. You may also see some problems with single filters, though they are generally less for higher-quality filters than they are for lower quality ones.

You may see strange color tints in your images, or a reduction in contrast. You may have increased problems with lens flare, or you may see ghosting. And these problems may be amplified if you're stacking filters. You don't need to have filters. You can still take great pictures without them. But sometimes a simple filter can take your image from fabulous to extraordinary, and with really minimal effort.

Use a polarizing filter to darken that already dark sky so that it's something really dramatic, or take the reflections out of the surface of a pond so you can see the stones and fish below. When the shoot was done, all that was left to do was get the images into Photoshop to compare how the lens filter looked in comparison to the warming filter in Photoshop.

The results are actually pretty amazing. The digital filter seems to have more of an affect on whites in the image than the lens filter does, but overall I think both images look great. I am a firm believer at getting things done in camera as much as possible though, so personally I would opt to use a lens filter over a digitally applied one.
