The 60mm macro is worth every penny, IMHO. Haven't tried the 30. The 40-150 f 1:2.8 PRO is excellent for tele-macro and a great walking-around lens.

The first one is very nice. Why don't you sharpen it more?
Thanks. I took your suggestion and tried Sharpen AI on it just now. The original post (signed on the right) is pretty much untouched except for a crop to about 2/3 of the original image. Here's the sharpened version (signed on the left), with about the same crop and nothing else but sharpening using motion blur (the left wings are a tiny bit out of focus and apparently moved and stopped during the exposure - 1/500 s!) The motion was quick and discrete enough to produce a clear doubling of the horizontal lines of the veins, more pronounced toward the wingtips. Sharpen AI did improve the sharpness in the rest of the picture, and the left wingtip area is also sharper but it sharpened the second instance of the wing too. I didn't apply much denoise.
I have been using the Topaz denoise and sharpen filters to good effect recently, and Gigapixel just the last few days. They can do remarkable things, but one does want to examine the results carefully and not over-do it. In this case it seems worthwhile.
Anybody else care to examine both and offer their observations?

Twelve-Spots resting on coyote willow and in a juniper tree in our yard in Eastern WA. The white spots are more pronounced on ours than some, so there are twelve spots on each pair of wings. Why they aren't 6-Spots or 24-Spots remains a mystery.

Nice work Tony - glad you had a good trip! We have very similar twelve-spots here in the inland NW. I'll post a couple in a separate thread.

Sometimes I find that when I pick a command after using clone, then adjust the settings for the new tool and try to use it, that the command selection has reverted to clone. I haven't been able to figure out what sequence causes this.

I thought I'd offer my retired OMD-EM1 here first. See the attached pdf for details. $350 would send this good starter kit to a good home. You'll want a better lens soon, and there are plenty to choose from.

Your fourth picture suggests that the bird is somehow dissatisfied with the pay scale...

That sounds great! We just took in the daily mass show, which was pretty cool itself, partly because I'm a little taller than average.

Arizona-Sonora Desert Museum, right? Nice airshow, and it saves a lot of trampling around in the desert...

I learned a useful trick to speed up hand splitting softwood and easier hardwood: Using a mid-weight axe (pref. single-bitted) or light maul, take a nice easy round swing aiming to put the bottom of the head near the near edge of the round. Just prior to impact, give the handle a little twist (CCW if you're right handed). The blade will bite and penetrate and the greater mass of the rest of the head will be a little off-center so it will rotate rather violently and pry the wood apart. It's pretty surprising how effective it can be once you get the timing right - one can walk around a large round and blow off 4" flakes without disrupting the round until you get down to an unstable core. If you get the timing really right, the head will flop clear over flat on the round and bounce back up, saving you some effort and greatly reducing the incidence of stuck tools. (Keep a grip!) Not as easy as a hydraulic splitter, though you don't have to move the rounds so much or lift them. You need some room - bad timing can bounce the axe alarmingly, and good timing with a strong swing can blow sizable flakes of wood quite a way. It's very gratifying!

At the short end of the zoom range a CPL will have different effects on different parts of the sky, depending on the angle of the polarizer and the angle of the sun relative to the axis of the camera. The result can be part of the sky is darkened considerably while the rest is unaffected.
There are things a polarizer can do with no more effort than putting it on and twirling the ring while observing the result that would take hours and serious skills in post - reducing glare off reflective surfaces in a scene with both specular and diffuse highlights for example.

PEMDAS rules applied:
8/2(2+2)= ?
8/2*4 Operation in Parens first
No exponents
4*4=16 Mult & Div in L to R order
PEMDAS rule properly applies only if the expression is taken as being written in a single line, such that "/" = "รท".
Excel doesn't interpret it that way: "=8/2*(2+2)" returns 16.
For PEMDAS to result in 1, the expression would have to be written 8/(2(2+2))= ?
Without some convention to determine the order of operations, 8/2(2+2)= ? would be ambiguous.
