John Bee: I fully agree(I too shoot RAW exclusively), though I've found that auto or PP WB to be surprisingly frustrating. Which didn't really come-up until I started shooting with a laptop at my side... and boy... was I ever wrong! The fact is(in my case) that not only would my WB be far out in the field but also that the colors(explicitly reds) were nowhere near that of my original compositions.

So now... with every lens capped, I carry a color calibration card everywhere I go.
And though that may sound like a hassle(it's not really), it has completely transformed my outlook on WB and color calibration.

For what it's worth, the caps were cheap(3 - 6.00 a piece), and the true color card was something like 19.00. Which is really good considering what it used to cost( 39.00 per cap and 150+.00 for a McBeth color checker card a few years ago)

Hope this helps
Yes, I agree again with your insight. In fact, I used to have problems, even with RAW, when trying to recover WB & correct colors. I learned that some soft ware is much better than others for this purpose. I have now rested in a soft ware which allows me to accurately get WB & color from a RAW file.

However, before this realization, I too was calculating WB for specific shoots. with a white card. Now I no longer have to do this.

That sounds interesting, would you mind sharing the name of that software?
I would like to test it against my current calibration methods and see if perhaps I might simplify my workflow as well...

Though I am skeptical with color balance though since camera sensors are not often good at reproducing specific colors.

K20D with the sears 28F/2.8 @ iso 1600 Jpegs resized and cropped only.
Some shadow noise but not too bad. I could have used noise ninja to clean them up I suppose, but I rather like the K20D noise as it gives street pics that dirty gritty look to them.








And here is one at ISO 3200

When it comes to high iso image, the lowly DL or the base sensor is really outstanding


From FA135mm at iso 1600




If you feel like counting hair or noise pixel go for this

Sure, it is with the Adobe Photoshop Elements 8 that I finally found success. It is not too expensive either, available for $80 on a sale day, perhaps even better now.

Yes again--colors can be problematic for cameras, particularly reds. But, with AE8, and with the free Helicon Filter soiftware, I am able to do whatever I wish with colors.

BTW, there are times when I m not interested in color accuracy, but am more interested in creating colors which I feel best highlight the shot. So it is rare I use the camera's given colors, even if they are spot on.

Yes, I have heard this about the DL, but seeing is believing. Thanks for this very nice contribution. BTW, where you been--long time no see--great to have you back posting here @ Pentax forums.

Simply great colors and IQ Jarvier! BTW, do you know any of these "Famous Dancers" who are advertised in your 2nd shot.

Thanks. In truth, I have never even been in that type of place.

Thanks. I was in a trip to HK and China until earlier this month. I did post a couple of images here and there of my trip. Life is back to normal now

Just curious - is that first image more heavily processed (like a large exposure push, or even added noise). It certainly does look "gritty"- considerably more so than I'd expect for ISO 1600. In fact, it looks "grittier" than the ISO 3200 shot to me. The other ISO 1600 shots look much more like what I'd expect.

Let me translate this one for Jarvier--it would go something like this (from google translate).

In truth, the little lady monitors Pentax Forums. LOL

Marc, The only PP i do is what comes out of the camera. The reason that picture looks super gritty is because it was too dark for ISO 1600 when I took it. Should have been at 2500-3200. I was going to delete that image, but it grew on me, more so because I know the conditions. Infact that sears lens tends to over expose by a full stop compared to my other lenses and so for it to be at +.3EV is really more like +1.3-1.5EV

So gritty and ugly and nothing special would be correct, but considering the conditions, the K20D did pretty good. Atleast you can see a picture
