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.

AutoHDR Free

AutoHDR Free is a free HDR software that can be used to process HDR files and create HDR images from multiple images. The features available let you align and merge images and process them as HDR image. The alignment tool comes in handy when you click multiple shots of a same frame and they go out of alignment.

There are various processing options which let you add and modify details, contrast, color, noise, shadows, highlights, and sharpness. There are some preset HDR filters available, which can be directly applied to an image, like: Sharp, Very sharp, Architecture, Landscape, Macro, People, Transport, Wildlife, Artistic, Black and white, Bold, Detailed, Natural, Timed, etc. You can also create your own presets that can be easily accessed.

Another option lets you enable safe smoothing at various levels: Soft, Normal, Strong, Stronger, or none.

This HDR software adds a default watermark, which can be disabled or you can add your own watermark under Advanced options.

The output image can be saved as JPG, PNG, GIF, or TIFF in this HDR software.

Luminance HDR is an open source HDR software. It lets you make HDR images using HDR Creation Wizard. You can add multiple images of same frame to merge and then change different properties, like: alignment, image exposure, anti-ghosting, etc. The options available for alignment are Auto align images, Hugin’s align_image_stack, MTB, and Auto-crop.

Use Tonemap operators and change the properties associated with them. Some of the Tonemap operators are Mantiuk ’06, Mantiuk ’08, Fattal, Drago, Durand, Reinhard ’03, Reinhard ’05, Ashikhmin, and Pattanaik. Based on the Tonemap you choose, you can adjust a bunch of image properties. This includes Contrast factor, Saturation factor, Detail factor, Contrast equalization, Color saturation, Contrast enhancement, Luminance level, Alpha, Beta, Noise reduction, Bias, Base contrast, range, Lower scale, Upper scale, Brightness, Chromatic adaption, Light adaption, Equation number, Auto cone/rod, Rod level, etc.

Options to adjust levels and set white balance for HDR images are available as well. Transformation options to rotate, crop, and resize images are also available.

This HDR software with extensive features also lets you batch process HDR images, copy EXIF data, perform batch tone mapping, and import FITS files.

This freeware to make HDR can open and process the following image formats: JPEG, TIFF, KDC, DCR, PEF, SRW, TKV, CR2, NEF, DNG, VDN, MRW, OFF, CLF, ANV, RAF, REFV, PTX, RAW, SR2, RW2, 3FR, MEF, MEFV, MCR, MCS, EIF, NRVV, etc.

HDR display options let you change the exposure, gamma, and offset values of an image. You can carry out exposure correction, ghost removal, automatic image alignment, and color balancing on a set of images to merge. Add Weight to an image with standard or mid emphasis. Manage Image Curve to manipulate linear, compute, standard, or user defined curve. Grayscale or RGB-color mode can be chosen and color density can be changed to either 8 Bit, 16 Bit, or 32 Bit per channel.

Transform your images using pan, zoom, rotate, flip and resize options.

You can create HDR images with DNG, CRW, CR2, MOS, RAF, 3FR, DCR, KDC, K25, PXN, MEF, MRW, NEF, ORF, RAW, PEF, X3F, SRF, SR2, ARW, TGA, VDA, ICB, VST, JPEG, PNG, TIFF, and PPM files.

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.

Fusion F.3

Fusion F.3 is a free version of Fusion HDR software. You can process a single image to add HDR effect, but it works extremely well if you add multiple exposure shots of the same scene to process HDR. It auto aligns pictures in case they are out of alignment.

These modes let you control threshold, smoothing, compression, detail contrast, shade, middle, light, histogram bounds, left shade, contrast, color saturation, color temperature, tone splitting, sharpness, exposure, exposure center, radius, etc.

The paid version lets you batch process HDR images by applying the same settings to multiple image sets, but that is not enabled in the free version. You cannot save the final result in any image format other than JPEG.

You can open and process RAW, JPEG, TIFF, and BMP images with this free HDR software.
