8 Best Free HDR Software For Windows

Here is a list of best free HDR software for Windows. These software let you add HDR effect to images by changing various image properties.

HDR stands for High Dynamic Range Imaging. It is an old practice of photography to make a picture look good and vibrant. It is a technique which enhances color range, brightness, sharpness, and shadow of a standard photo and adds more dynamic ranges.

There are two ways to create an HDR image. The first method lets you enhance a single image by adding various effects to it. The second method makes use of multiple shots of a single frame shot in different exposures (under, normal, and over).

Nowadays, HDR mode comes built in with cameras and mobile phones, but you might need more dynamic detailing in your photos.

I have tried to find the best free HDR software to add HDR effect to a single picture and merge multiple shots to form a HDR image. Go through the article to know more about these tools. Here you will also learn how to create an HDR image and how to merge multiple photos to HDR.

My Favorite HDR software:

My favorite HDR image processing software is AutoHDR Free. It can merge multiple images to an HDR image. You can also modify color range, contrast, details, highlights, sharpness, shadow, etc. to get desired result. Various presets are available which can be used to easily apply HDR effect on images. You can also add watermark to an HDR image and output can be saved in various image file formats.

GIMP




GIMP is an open source image manipulation freeware, which is the most popular Photoshop alternative out there. Not many people know that it can be used to create HDR images as well. There is not any direct option or special feature to apply HDR effect, but you still can create an HDR image either by using Photoshop HDR plugins, such as Photomatix or by following a series of steps.

How To Create HDR in GIMP without Plugin:

Although plugins give satisfactory results when you apply HDR effect, you can use manual process to get similar or better result. This process includes darkening and over exposing the original photo separately, then adding these three photos as different layers in a single tab. By adjusting opacity and other parameters of these layers, HDR effect can be achieved.

You can use the same process to apply HDR effects to photos using other image editing software, such as: Paint.NET.
