Health behaviors are shaped by the context in which people live. However, documenting environmental context has remained a challenge. More specifically, direct observation techniques require large investments in time and resources and auditing the environment through web-based platforms has limited stability in spatio-temporal imagery. For comparison, we examined validity using Google Earth imagery. Thirty-seven different attributes were captured representing three broad constructs: land use, traffic and safety, and amenities.

There are several factors that affect the depth of field. You can increase the depth of field on your camera by:.
There are a few common reasons why the electronic trigger cable might not be actuating the camera shutter. Vignetting is the result of less light reaching the edges and corners of a photo than the center of a photo. Vignetting manifests itself as a pattern of stripes in a panorama. You can adjust camera settings to minimize vignetting and you can reduce vignetting using an image editor before stitching the photos together. Post processing photographs to remove vignetting before stitching At times you may need to rely on editing your photos in post-production because your camera adjustments during the capture of the panorama were not enough to eliminate vignetting or the settings would have prevented you from capturing the images due to low light conditions.
Note that you are able to adjust jpeg format images to minimize vignetting, but you are able to make a more aggressive adjustment to files that are in the camera RAW format. Skip to navigation Skip to content Skip to sidebar Membership. Introduction 1. This is especially useful for nighttime panoramas.
Shoot a test panorama while watching for settling through the camera viewfinder. See Chapter 1. Wind gusts or vibration might have disturbed the lens and camera.
Use a faster shutter speed that is at least the reciprocal of the lens focal length. Consider increasing the ISO to allow for a higher shutter speed if there is not enough light. Attempt to shield the lens and EPIC Pro from the wind by placing it to the side of an object such as a tree, car trunk, or a large collapsible portrait reflector.
Consider taking two or three photographs per position at the same exposure to increase the probability that one of the photographs is not blurry if the disturbance is intermittent. Auto focus may not be yielding consistently focused images. Note that a zoom lens will normally have two values printed on the lens.
Aminimum effective aperture at the shortest focal length and then a slower effective aperture at the longest focal length. Consider using manual focus or a mixed manual focus and auto focus approach with areas such as sky, water, plain walls that do not contain detailed features.
See Chapter 2. There is a point at which you will experience diminishing returns in image quality while increasing the aperture value to maximize the depth of field. You may be able to use auto focus to increase the sharpness of your panorama depending upon your subject, available light, lens, and camera.
Using auto focus allows you to move the critical focus for each position in your panorama. While using auto focus you did not focus the lens before starting your panorama. Press the shutter button on your camera halfway to engage the focus system and achieve good focus before starting your panorama.
Autofocus is not achieving focus and not taking pictures. A minimum effective aperture at the shortest focal length and then a slower effective aperture at the longest focal length. Verify that a memory card has been inserted into the camera and that it is not full.
Verify that the camera is powered and that there is sufficient charge on the EPIC Pro battery to complete a panorama. If you plan on using manual focus, verify that the lens is in the manual focus mode. If you plan on using auto focus, ensure that you are able to achieve focus by pressing the shutter button half way to engage the auto focus sub system. Check the servo mode or release policy of the servo mode. Different camera manufacturers use different terms for the servo modes.
Typically a single servo mode uses a focus policy where the camera will not actuate the shutter unless the auto focus system communicates that a good focus was achieved. On some cameras you can change the default focus policy to a release policy where the photograph will be captured regardless of whether the camera achieves good focus. Continuous servo modes typically have a default policy of release where the trigger will be actuated regardless of the whether the camera achieved a good focus.
Release policy can cause more problems than it solves depending upon your equipment and the subject you are photographing. Go through the Set-up steps in Chapter 2. Note: Remember that you must repeat this every time you change the camera, lens or focal length.
Make sure that your tripod is on steady ground. Make adjustments for vertical or horizontal lines in your panorama. GigaPan Stitch aligns the larger elements of photos, and thus might ignore vertical or horizontal lines such as poles and window frames. Try to avoid taking panoramas with too many vertical lines in the foreground.
Try using a third-party tool to stitch your panorama. Turn to Chapter 2. Note : This is a time-consuming process, and should only be used when necessary. However, it may be necessary for panoramas that have subjects that are both close and far away, and macro panoramas.
The aperture value is inversely proportional to the diameter of the diaphragm opening. Use a smaller focal length such as mm versus mm. Use a petal type lens hood or no lens hood. Newer Nikon and Canon cameras have vignetting compensation settings that help reduce vignetting for supported lenses.
Nikon vignetting correction controls are located in the custom function menu. About Us Site Map. Member Log In Username Password.

In such cases, use a lesser amount of zoom or upgrade to the top Epic Pro model, which has smaller motor increments and also can support much heavier camera-lens combos. However, it has one major drawback for gigapanographers, namely you have to reset the shutter start delay button after each exposure. When fully zoomed, the shutter delay, in conjunction with the programmable delay function on the Epic , allow the tripod and camera to 'settle' after the shutter button has been pressed. Not a big problem with a dozen or so shots, but if you start shooting upwards of two dozen images then it becomes tiresome. So, if contemplating buying a point and shoot, or a camera that has no cable remote, check whether the start delay stays on in manual mode after each shot Slap can be minimised by using the "mirror up" option available on some cameras, or eliminated on cameras that have electronic shutters.
