Picturenaut: Create HDR Images From Bracketed Exposures Using Filters

Advertisement

High dynamic Range Imaging, aka HDRI, or simply HDR, is a technique that allows bringing out the range of intensity levels (in images), which are found in real scenes, such as direct sunlight or faint moonlight. HDR techniques are geared towards the representation of contrast between photos of a single imagery. Non-HDR cameras, for example, take pictures at a single exposure level, and hence, have a limited contrast range. This often results in the loss of bright and dark areas of a picture, which can be corrected by using similar images and using HDR techniques. Picturenaut is a HDR imaging application that enables users to create High Dynamic Range (HDR) images from bracketed exposures. All you have to do is to select the input images, and Picturenaut will adjust the exposures in a single HDR image, with automatic exposure correction, picture alignment and color balancing. Additionally, you can tweak the image by managing the tone mapping for creating a desired image effect. Picturenaut provides 8-bit, 16-bit and 32-bit modes, gamma adjustment, support for RAW images and real-time preview. Furthermore, this application is fully capable of making use of multi-core processors.

To get started, simply click Generate HDR image from brackets exposure option and add images. Once done, select required options, including Exposure correction, Ghost removal, Automatic image alignment and, optionally, color balancing. You can also select a weighting preference (Standard or Mid-Emphasis), and choose a Curve (Linear, Compute, Standard Curve or User Defined). Click OK to create the HDR image.
