TIOParams.EXIF_ExposureTime

Declaration

property EXIF_ExposureTime: Double;

Description

The exposure time of the photo (reciprocal of the shutter speed). Unit is second.

Note: Use EXIF_ExposureTime2 for easier access to the value.

Example

if ImageEnView1.IO.Params.EXIF_ExposureTime > 1 then
  // It will be something like 4 i.e. 4 seconds
  sExifExposureTime := IntToStr( Round( ImageEnView1.IO.Params.EXIF_ExposureTime ))
else
if ImageEnView1.IO.Params.EXIF_ExposureTime > 0 then
  // It is something like 0.25, which translates to 1/4 second
  sExifExposureTime := DoubleToFraction( Round(1 / ImageEnView1.IO.Params.EXIF_ExposureTime ))
else
  sExifExposureTime := '';

// Write the value back to image parameters
if pos( '1/', sExifExposureTime ) > 0 then
  ImageEnView1.IO.Params.EXIF_ExposureTime := 1 / FractionToDouble( sExifExposureTime )
else
  ImageEnView1.IO.Params.EXIF_ExposureTime := StrToInt( sExifExposureTime );
