Of the many factors that make an image dull looking, blown highlights are one such that contributes to it. Blown highlight occurs when the amount of luminosity in a particular scene is way too much than the amount the sensor can cope up with. For example, an overall picture might look correctly exposed, but the sky may be overcast brightly making it fully overexposed and all white. Though photo editing services like photo clipping service can do their best to correct these flaws, given below are some tips you can try to avoid blown highlights.
Learn How to Use the Histogram
You may have seen this feature in your camera; however, you might not be much aware of the importance of this feature. The graph you see displayed on the LCD screen is quite a powerful tool a camera has. It displays the distribution of the exposure of light with brightest areas in the right and darkest on the left. Any frequency that falls on the right is said to be a blown highlight. If it happens, you should either close down the aperture or increase the shutter speed. This is one of the techniques that professional who give photo clipping service know very well.
You need to have a deep understanding of the exposure limit of your camera before capturing the images. Not only should you learn about the dynamic range of your camera capability, but also you need to visually read the light before you lift up the camera to capture the picture. Look for the tonal range from the lightest to the darkest areas, and think how dark shadows of objects in front will be while capturing it. After making suitable adjustments, capture the picture.
JPEG file formats are fine for most things, however, when you need the best quality picture or if you are working in complex lighting, RAW file format will be the best choice. If you use a RAW file, your sensor you will get the maximum dynamic range. A shot that appears to include blown highlights in JPEG would have been recoverable if it were shot in RAW file format. Even though there are certain limitations to this, by combining the RAW shooting with histogram monitoring, you can easily learn the maximum exposure capability of your camera.
