Some uses of Credo WS back

Creative photographers will explore their art using the Leaf Credo WS using techniques such as:

  • Woods Effect — landscape images with dark green foliage becoming very bright and light blue skies become very dark.
  • Portraits — skin blemishes are typically much less visible in IR and skin "glows”.
  • Invisible flash — Use a flash filtered with an IR-pass/visible-block filter and you can do flash photography without anyone else being able to see the flash.
  • Macro — Some flowers show patterns in the IR space that aren't in the visible spectrum (more common with UV than IR) .
  • • Science/ Art conservation – In near IR light and near UV light you can reveal invisible paint layers that will help is research and in repairs of old masters work.

On Technical cameras

Because technical cameras don't utilize autofocus or a viewfinder, it does not matter that you can't compose or focus through-the-lens when using an IR-pass/visible-block filter. The Leaf Credo WS delivers stunning quality that has been Leaf’s trademark for many years.
