I found the reason for purple color with Luminace HDR. I had default RAW settings in white balance. When I changed "predefined D65" to "Camera", purple colors disappeared:

Predefined D65b => Camera

Has anyone used freeware softwares easyHDR and Luminace HDR to make HDR photos?

I tryed to do "HDR" photo from single picture (Pentax RAW file) and I managed to get reasonable good with easyHDR (with default settings), but Luminance HDR result was more a less purple.

What is your opinion, basicly which to use or use both depending used photos?

Fine and unusual image and a good idea. Expecially the later one.

Here is same butterfly on both side taken through the window:


and opposite side:

So, sign on the front is better solution. That's the way what painters do and why not photograps can't sign same way.

Thanks

Mayde it's better to sign the photo on the frame (backside the frame) or on the backside of the print in such a way that it does not show through the print.

I have couple of photos which I'm going to sell (try to sell) them printed and framed. I wonder which will be the common practice, signing the photos by hand or by e.g. photoshop (to the front right corner or to the backside) or let them be without signing at all?

So, it's sound of shake reduction system.

I found more information on from PentaxForums.com:

"There is an exploded view of the Shake Reduction assembly on our Web site, but it doesn’t explain how the assembly itself works. (The sensor is on a plate containing motion sensors and electromagnets. The plate rides on bearings between two other plates, one of which contains permanent magnets. When an exposure is made, the plate with the sensor is held in place by a balance of forces between the electromagnets and permanent magnets. Shake Reduction is turned on, input from the motion sensors will be used to vary the pull of individual electromagnets and adjust the sensor position."


So when SR is OFF, "When an exposure is made" might mean that SR holds the sensor on place only when you press the shutter to the bottom, not half press.

And when SR is ON, SR system tries to compensate the camera movement by moving the sensor with electromagnets.

My conclusion is that SR makes sound, whether SR is On or Off.

Thanks

Will (Pentaxophile), what are you mean by "edit- but not in live view"?


I made quick and dirty test with SR Off/On and here are results. Left is SR Off and right SR On:
