How do you avoid noise and artifacts when shooting in low-light or high-ISO situations in architecture?

由人工智能和领英社区提供技术支持

Shooting in low-light or high-ISO situations can be challenging for architectural photography, as you may end up with noise and artifacts that degrade the quality and detail of your images. Noise is the random variation of color or brightness in pixels, while artifacts are distortions or errors caused by compression, processing, or editing. Both can affect the dynamic range and contrast of your architectural photos, which are essential for capturing the mood, atmosphere, and style of a building or space. Fortunately, there are some tips and techniques that can help you avoid or minimize noise and artifacts when shooting in low-light or high-ISO situations. Here are six of them:

1 Use a tripod

One of the easiest ways to avoid noise and artifacts is to use a tripod. A tripod will stabilize your camera and allow you to use a lower ISO and a slower shutter speed, which will reduce the noise and preserve the detail and sharpness of your images. A tripod will also help you compose your shots more carefully and avoid camera shake or motion blur. You can also use a remote shutter release or a self-timer to avoid touching the camera and introducing any vibration.

2 Choose the right ISO

ISO is the measure of your camera's sensitivity to light. The higher the ISO, the more noise you will get in your images. Therefore, you should always try to use the lowest ISO possible for your shooting conditions. However, sometimes you may need to increase the ISO to get a proper exposure or to freeze any movement in your scene. In that case, you should avoid using the extreme or highest ISO settings on your camera, as they will produce the most noise and artifacts. Instead, use the lowest ISO that still gives you a good exposure and a fast enough shutter speed.

3 Shoot in RAW

RAW is the format that captures all the data from your camera's sensor without any compression or processing. Shooting in RAW will give you more control and flexibility over your images in post-production, as you will be able to adjust the exposure, white balance, contrast, and other settings without losing any quality or detail. You will also be able to use noise reduction software or tools to remove or reduce the noise and artifacts in your images, without affecting the dynamic range or contrast. Shooting in RAW will require more storage space and processing time, but it will be worth it for the best results.

4 Use noise reduction software or tools

Noise reduction software or tools are programs or features that can help you remove or reduce the noise and artifacts in your images. There are different types of noise reduction software or tools, such as in-camera noise reduction, which applies some noise reduction to your images as you shoot; external noise reduction software, which allows you to edit your images on your computer and apply various noise reduction algorithms and settings; and noise reduction plugins or filters, which are extensions or add-ons for your editing software that can enhance or refine the noise reduction process. You should experiment with different noise reduction software or tools and find the one that works best for your images and style.

5 Use exposure bracketing and HDR

Exposure bracketing and HDR are techniques that can help you capture the full dynamic range and contrast of your architectural scenes in low-light or high-ISO situations. Exposure bracketing is the process of taking multiple shots of the same scene at different exposure settings, such as underexposed, correctly exposed, and overexposed. HDR, or high dynamic range, is the process of combining these shots into one image that has a greater range of tones and colors than a single exposure. Exposure bracketing and HDR can help you avoid noise and artifacts by reducing the need for extreme ISO settings or post-processing adjustments. However, you should use these techniques with caution and moderation, as they can also create unrealistic or unnatural effects if overdone.

In my experience HDR can cause increased noise in some situations but does help in others, so it needs to be watched. It can even produce an image with reduced noise in some parts of the image and greatly enhanced noise in other areas. One trick I've used is to use different sets of bracket for different areas of a final image.

6 Check your histogram and preview

Finally, one of the best ways to avoid noise and artifacts is to check your histogram and preview on your camera's LCD screen. The histogram is a graph that shows the distribution of tones and colors in your image, from dark to light. The preview is a small image that shows how your image looks on your camera's screen. By checking your histogram and preview, you can see if your image is properly exposed, has enough detail and contrast, and has any noise or artifacts. You can then adjust your settings accordingly and reshoot if necessary. You should also zoom in on your preview and check the edges, corners, and shadows of your image, as these are the areas where noise and artifacts are most likely to appear.

Something to keep in mind if you're shooting in RAW is that your preview is a JPEG and not RAW. Therefore, knowing and understanding what the histogram is telling you is essential for high end photography. Also, it's been my experience that high ISO/long exposure noise is more noticeable in the darker areas of the image. Provided the scene doesn't have a wide dynamic range, you can exploit this element by over exposing the dark areas (without sacrificing the highlights) and correct it afterwards in the software you use (Lightroom, Capture One, etc).
