With many thanks Clive introduced and welcomed meeting speaker Mr Brian Gromett.
Subject: Exposure/Dynamic Range & Filters.
With Diagrams Brian talked about the over and under exposure or images comparing this to a full and empty bucket!!
– Dynamic range of images together with diagrams of histograms explaining
the under and over exposure of highlights and shadows – The exposure
triangle, ISO/exposure/aperture, getting the same exposure using different settings – Shutter stops –
Depth of field, using different f stops f1.4 to f16 - The use of different shutter speeds for
capturing fast moving objects (500th Sec. plus) and low light images (5secs.) - Auto Focus points.
- Exposure compensation to add or subtract brightness to an image - Metering modes, evaluative/center weighted/spot (Brian
uses mostly center weighted).
Brian brought several old and new cameras to demonstrate to the meeting the various old (Film) and new (Digital)
camera settings and lenses.
To close his presentation Brian talked about and demonstrated the use of various types of filters, most of which
can now be replicated in photo editing software.
Frances gave a vote of thanks to Brian for his excellent and informative presentation.
With our grateful thanks Pat Henson presented to our group several excellent photo editing books for members
Bob & Clive.
