True Macro?
Apr 9, 2012 00:39:58 #
Maybe Nikonian 72 can answer my question. Can this photo be considered a true macro shot?
The exif data says focal length is 4mm with a max aperture of 3.36.
What is meant by max aperture?
Oh, this was shot with a Fuji 14mp bridge camera in macro mode.

This is not a macro-photograph. This is a close-up photo.
What is the sensor size of your camera? A typical APS-C (cropped) sensor is about 24-mm wide x 16-mm high. At 1:1 (life-size), a macro-photo of a U.S. quarter (24-mm diameter) will fill image side-to-side, and a U.S. dime (17-mm diameter) will fill image top-to-bottom.

In order for this to be a macro-photograph, based on your narrowest CCD side of 4.55-mm, this flower would have to be about 1/3 * 4.55 = 1.5-mm wide. It can't be that small, so this must be a close-up photo.Nikonian72 wrote:

Gottcha" But I have seen the exif data on many different cameras and they all have a line telling what the max aperture is. Why is this important?tainkc wrote:

IMO, the only reason for know max aperture is for viewing brightness during focusing. It is a known characteristic, and appears in Exif info, along with a lot of other useless stuff.I have seen the exif data on many different cameras and they all have a line telling what the max aperture is.
