Raw Image Data Processing, Stitching, and Blending Very long exposures (using strong neutral density filters or using image stacking techniques to average hundreds of exposures) are also useful to blur and “erase” the moving objects such as cars and people.ġ91-megapixel image taken in Acadia National Park (Maine) by Aaron Priest, member of VAST. Sometimes, the best option is to wait for clear days where there aren't moving elements in the sky. Other methods can help to reduce the motion issues. This requires a lot of patience and a fine-tuned awareness for all of the details happening in the scene.” We'll also do things like wait for a moving object to be completely in or out of a frame before we expose the frame, so as not to cut off the object between different exposures. “For example, if the clouds are translating to the right, we'll shoot the array of exposures from left to right to minimize the apparent rate of that motion. “We are very careful in our shooting process to minimize the number of motion problems we'll have,” said Piech. Moving objects and passing clouds during the capture phase are a big challenge. Depending on the desired resolution output, the photographer can take anywhere from 20 images up to several hundred for the largest gigapixel projects. Additionally, the VAST photographers use some of the best prime lenses up to 800mm to minimize typical adverse optical artifacts such as noise, distortion, diffraction, and chromatic aberration. These systems are designed to mount high-resolution cameras such as the Canon 5DS or Nikon D850. The specially-made gimbal mounts enable the camera's perspective on the scene to remain unchanged as the equipment rotates to expose the matrix of images.

All of the gear must be extremely precise because the tiniest amount of mechanical vibration or perspective-shift during the exposure process can ruin an entire photo. The exposure process utilizes a number of specialty tools such as rotational gimbal mounts, modified tripods, wind shields, and field computers. Even small changes in lighting, timing, or conditions can dramatically alter the mood of a scene, especially because it can sometimes take hours to expose the hundreds of images necessary to create the final photo. The team plans for a time to shoot the photo with a keen awareness of how the scene changes depending on the weather, the time of day, and the time of year. For any given subject, there are countless different angles, perspectives, and conditions to consider.

Scouting and Pre-VisualizationĮvery photo starts with a great deal of location scouting and brainstorming. The basic concept is to capture several images and stitch them together seamlessly in post-production with the help of specialized software. All together, the team has collected many awards all over the world.Ħ,410-megapixel photo of N.Y.C. The list of artists involved in VAST gathers an impressive sum of talents such as Aaron Priest, the master of 360-degree photography, or Scott Dimond who is an expert in numerous techniques including near-infinite depth-of-field capture via the focus stacking technique. The VAST collective is open to collaboration and skilled photographers are welcome to join the team. In doing so, we aim to be constructive contributors to the broader photography community, sharing our methods, ideas, and work.” Our aim is to operate at the intersection of those two communities, helping to bring together the best of what both have to offer. Both communities are producing superlative photographs, solving challenging problems, and evolving their craft. At the same time, we also have a great deal of respect for the work the community of artistic photographers is doing. Photographer and VAST Founder Dan Piech said: “We have a great deal of respect for the work the community of gigapixel photographers is doing.
