Florida photography up to a minute to understand the depth of field

May primary users don't know what is the depth of field, is actually very simple easy to understand ^-^ it means to be taken in comparing dongdong produces a clear image of the nearest point to the farthest point of the range. That is clear and fuzzy point distance. Depth of field also is a worthy of Word. In short is: large aperture (F value) + Telephoto + macro = small depth of field depth of field size may primary users don't know what is the depth of field, is actually very simple easy to understand ^-^ it means to be taken in comparing dongdong produces a clear image of the nearest point to the farthest point of the range. That is clear and fuzzy point distance. Depth of field also is a worthy of Word. In short is: large aperture (F value) + Telephoto + macro = small depth of field depth of field size issues: clear point to blur the greater the distance between the points is the depth of field; on the other hand is the small depth of field. How to adjust the depth of the non-stop, small small depth of field; aperture, depth of field. 2 Why are inversely proportional relationship of the small depth of field? in order to highlight the ring, the blurrier clear and intentionally blur the necklace. Let others know I shot a glance's main object is the ring instead of rings and necklaces. Long depth of field: depth of field length, the background and foreground are clear, necessary for shooting landscapes or use background and foreground form. Another problem, hyper-focal depth of field is very deep depth of field, which does not focus camera used this principle
