Excellent!! Did you use a filter for the sun and/or the water reflection? What metering mode did you choose?

Kevin Childress on November 10, 2011

Thank you, Draken - it's my favorite recent photo! I was using a circular polarizer which in this case only helped to darken the blues. That neat star pattern on the sun is caused by the blades of the aperture when stopped down to a very small diameter (a tip I picked up from one of whoelius's photos. The metering mode here was set to matrix.

Good to hear from you - I hope all is well.

I wait your uploads because I always find very good photos (you know you are among my favorites on Google reader).

By small diameter you mean f stops 11 and higher?

Everything is fine, I also hope you are both well!!

Keep taking excellent photos.

Thank you, Draken, I am truly flattered. Oh, and thank you for the tip on Google Reader - it works wonderfully! Yeah, in my experience so far I have only been able to get that star-patterned effect with apertures around f/22, although whoelius pulled it off at f/9. I suspect the number of blades on the aperture has something to do with moving that range between different lenses, and maybe the angle to the light. whoelius' example had 9 diaphragm blades where this lens of mine only has 7 diaphragm blades.

Lovely shot.

Oh now I see I'm kinda famous. :D

p.s. - If you use Live View, you can turn the camera around and look into the lens to see the shape created by the aperture blades when you thumb through the apertures. Many blades are rounded; others are mostly rounded save for a straight end (and, in that case, sunstars will only appear in the smaller apertures); and others are fully rounded, so the opening is always rounded and thus there can be no sunstars. I believe the 18-200s have well-rounded blades, so it makes sense that they only show a heptagon once stopped down quite a bit.

One of the (many) big reasons I stick with Nikon is the odd number of aperture blades. These give much more interesting sunstars than Canon's cheesy symmetrical ones.

Oh and if I can squeeze in a p.p.s. - see if you can't pick up a 28mm f/3.5 on a craigslist or a kijiji or whatever. It's beautifully constructed with good sharpness, I can get sunstars on it from f/4... and it can be reversed (with a reversing ring) for some of the closest close-ups available with a Nikon SLR. I think I got mine for about $60.

Thank you, whoelius - this is one of my personal top favs for 2011.

More excellent tips 'n tricks ... always very much appreciated and almost always put to use! :)

I'm liking the sounds of the 28mm lens you mentioned and you did get a good price (sounds like). I haven't really considered looking for used lenses as a cost saver ... will see what I can find!

All the best!
