It is strongly recommended to shoot keeping the same focal length for all the pictures you take.

Following a few tips are provided so as to pick the proper photographic gear:įull-frame cameras: use lenses with focal length value between 25 and 50 mm Īps-c cameras or lower sensor size: use lenses with focal length value between 18 and 35 mm considering a crop factor value between 1.5 e 1.6

That is the way to get bigger pixels in the images even though less Įvery survey has its own features and conditions so choosing the most suitable lens for that depends on both environment status (light, obstacles on field, user movement capability) and features of the survey subject/scene. For instance, if a 36 megapixel full-frame reflex (35.9 x 24 mm) is being employed it is worthwhile to shoot at a lower resolution than the maximum provided. You’d better draw your attention to pixels size rather than pixels mount for each picture. Pixels size must be higher than 2 µm therefore it is strongly recommended to exploit camera sensor bigger than 1/2.3″ even if smaller sensors may be used depending on the accuracy you want to reach That’s why DSLR cameras (reflex) are usually recommended even if both mirrorless and bridge camera can fit that need.Ĭamera sensor is the real highlight of the matter and the following hints could be quite helpful:

High-end cameras do not always lead to better result Ī good camera must allow a full light management in order to control each exposition value. What you’d better keep in mind when picking your gear:Ĭamera performance is not provided by its megapixels resolution
