As you can see the original is rather blah as I was trying to moderate exposure between the poorly lit sign (the sun was shining into the lens &#8211; note how flare free the image is, especially as I do not use a lens hood) and the brightly lit beach.  A separate attempt using fill-in flash looked too artificial for my taste, like one of those over-lit 1950s outdoor Hollywood musicals.<\/p>\n<p><center><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.pindelski.org\/Blog\/BeachSign_before_after.jpg\" width=\"700\" height=\"493\" alt=\"\" \/><\/p>\n<p><i>Original on the top.

The sheer idiocy of the sign testifies to the fact that the least able in any society work for government.<\/p>\n<p><center><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/www.pindelski.org\/Blog\/BeachSign.jpg\" width=\"814\" height=\"548\" alt=\"\" \/><\/p>\n<p><i>Stop!

Things are made a lot easier by the fact that the Panasonic G1 has one of the very few viewfinders which shows 100% of the image &#8211; most crop 3-5% making it impossible to exactly preview the saved file.<\/p>\n<p> Lightroom3 is a powerful, efficient photography tool.  The enhancements in Lightroom3 have now almost totally obsoleted my use of Photoshop for which feature, alone, I am immensely grateful.<\/p>\n<p>Thank you, Adobe.
