Photoclub Alpha

Here’s a question which came in to my email just now:

“Could I process a RAW file in Photoshop to achieve a similar effect as if I had used a Polaroid lens filter?
Or would I be better just using the Polaroid filter?”

The answer is that you can never imitate the effect of polarizing light (which changes the way reflective surfaces look, and deepens or lightens the sky blue according to the zone of the sky relative to the sun’s position. But you can use Adobe Camera Raw (CS3 versions) to deepen skies you never thought could be rescued.

SEASON’S BEST wishes from David and Shirley here at photoclubalpha! You know how the pursuit of photography can take over your plans? Well, we were offered a short break in Portugal (inspection visit terms, 2 hours wasted time and iron constitution to resist sales pitch) and took it up for the week before the holiday. A chance of some sunshine and different subjects for the Alpha 100 and 700! Of course, it rained so hard the entire Algarve coast was flooded, and the only sun we saw was the sunset as we landed. However, back at home, the world was in wonderland mode even as we drove back through the Lake District with the moon rising over frosty hills lit by the last pink light of the sun. The next day, Kelso was in full sunshine but -7°C and freezing fog had coated everything for three nights in pure white. So here are our Christmas cards from Kelso, courtesy of the A700, 16-80mm, and Minolta polarizer.

THE PROBLEM of darkened extreme corners with the 16-80mm CZ Sony lens definitely exists. They are there in many of my shots, with or without SSS anti-shake enabled, significant softly darkened corners. Everyone is saying this must be due to filters, and at least one of Forum regulars has emailed Zeiss about this issue (and got a reply almost admitting that the lens falls short of ideal design). But is it?
