Dandelion

One of the 24 images used.

Dandelion

This is another composite photograph of 24 separate photographs focus stacked in Photoshop.

Each photo only has a little of the dandelion in focus, a very shallow depth of field of a couple of millimetres.  The photos are loaded as layers in Photoshop or another suitable software.  The images are first aligned to a best fit by the computer.  When that is done focus stacking is started and takes several minutes while the computer does loads of number crunching.   At the end of the process the computer produces the final image, a moment of pure magic and very satisfying to see.  The 24 original photographs that appeared to be all out of focus are now one in focus and showing fine detail.

Exif details for the 24 photos are much the same, only the point of focus is changed each time, either by moving the whole camera forward on a rail or by turning the focus ring a little each time.

Camera  Nikon      D800

f/16  to get as much depth of field as possible to keep the number of photos low.  in this case 24 photos  but could be over 60 sometimes.

Exposure time was set at 1/250 sec but the photos were taken by flash TTL metering

Metering mode was Spot with auto focus off.  (full manual)

Lens was the Nikon 105 macro for full frame.

The background was black art card but this has come out as grey because of the total number of flashes.  The flash was camera mounted with an overhanging reflector to direct the flash down beyond the end of the lens.

A few water drops were placed in the canopy to see how they would look.

There are some errors where the computer was not quite able to resolve what should be in focus.  This is noticeable if you look closely where two stems cross one behind another.

If you get the chance you must try focus stacking if you have not already tried it.




Swan

Swan Lake

Swan

The swan was on the other side of the river but I waited for 10 or 15 minutes, it came over and danced. You can listen to the music and look at the photo.  I think the darkness of the water and the dance of the swan works well with the music, like a ballet.  :)

Randalstown Viaduct

This was the railway viaduct over the river Maine at Randalstown, Northern Ireland.   The railway no longer follows this route so the viaduct is now used for pedestrian traffic.
