Introduction to Fotor's HDR feature:
HDR (High Dynamic Range) photography takes three photos with different exposures and combines them into a single image to bring out the best light and tone in each part of the photo. Fotor.com is the first photo editor offering online HDR features that allow you to capture highlights, shadows and striking details without the need to download expensive software. Our HDR feature contains revolutionary HDR technologies including Local Tone Balancing, Photo Alignment and Ghost Reduction that dramatically increase the accuracy and quality of photos at the fastest speeds available today.
