Realtograph's photos are optimized with a High Dynamic Range (HDR) stacking process to maximize the amount of details in all areas of rooms from the brightest to the darkest areas. Three different photos are taken; one intentionally overexposed (too bright) to retain the details in the darkest areas, one intentionally underexposed (too dark) to retain the details in the brightest areas and one evenly exposed to get details from the mid-tones. In the editing process, the three photos are merged into a single high dynamic range photo. Delivery of the highest quality photos of your property is Realtograph's priority.
