I prefer shooting RAW since I can correct WB. Memory is so cheap nowadays so saving space is no longer my concern.
By the way, some people prefer shooting JPEG, other prefer RAW; never a controversy. Calling people who prefer shooting RAW bragging or superior air is insulting and useless in conversation.
Regards,
Peter

The raw file contains raw pixel data rather than an interpolated/demosaiced photo like a JPEG. This means that the raw processor may be able to do a better job of interpolating the file (decoding the bayer pattern) than the camera. There is no single best way of doing this, so some might enjoy the flexibility when it comes to artifact removal. The photo will most likely look slightly different (especially around edges and file details) when developed using two different raw converters.
Yes, but that dynamic range is discretized into 8-bit values per channel (24 bits total) in JPEG versus 14 bits in RAW (42 bits total). So RAW has the potential to represent 2^18 times more colors (that works out to 260k times more colors). 0 in jpeg (i.e. complete darkness) might be represented more precisely in a raw file, and it usually is. I've had JPEGs that looked almost completely black turn into perfectly good night shots after +3 stops in ACR, whereas the JPEG simply had too much noise.
My stance is that raw mode gives you endlessly more control, as it should. However, out-of-camera JPEG files will usually end up better color-wise unless you apply a profile to the raw file or spend a while adjusting the sliders (away from the raw processor's default presets). Thus, the main trade-off is time spent during post. That's why I use RAW+: you've got the JPEG as a starting point and a color reference, and if that isn't enough to work with, then the RAW file can be used to recover extra detail.

DPI means dots per inch and is essentially a meaningless number except when you are printing. Your image size is 3264 x 4928, that is what is important. The DPI translates that image size into a physical dimension based on the display medium. For high quality ink jet that might be 300dpi (although most articles I've read say 240 is indistinguishable) or 5dpi for a huge billboard. The camera (or jpeg engine) assigns a default dpi when the jpeg is cooked. This can be changed in the printing or editing software.
A digitally stored image has no physical dimensions until those are assigned and that is determined by the output or display method.

It looked a lot better in the viewfinder. I think it needs more contrast.

Just give up ever hoping for anything anti democrat ever appearing on this forum you will learn that all conservatives are wing nuts or nitwits that all Republicans may as well drop dead or be though of a liars or hellspawn by the vast majority of posters in this forum. There a a few of us that are soooo stupid that we continue to post from time to time but I think we are masochists. But welcome to the forum and post away oh by the way the only acceptable sources of information are the huffington post, the daily kos, Msnbc, and other liberal new outlet. Should you watch FNC you are an idiot that enjoys being lied to and you have swallowed the lemonade brewed by the secret world order led by the Koch brothers and a few others. Ok I think I covered all the bases for the uninformed conservative new to these threads. Carry on there is nothing to see here take you camera and go outside.

Basically, because on this forum, conservatives are attacked until they are silenced.
I consider myself moderate, more likely to lean towards the demaocrats, but reading the deluge of anti-Romney posts on this forum, I feel like I must be an out and out right-winger.

Took it to the balloon rally in Prosser, WA this morning (a two hour drive from my home in Oregon) and had alot of fun.
Here is one example:
Lens was 24mm f2 internal focus Pentax.

I got my new K-30/18-135 kit from Amazon last Wednesday and have spent this past week learning and adjusting to the newer features and capabilities, as well as strangely placed buttons :lol:. My K-r has been a trusty little camera, but the K-30 is superior in every way. It's too early to do a real review of the K-30 yet, but I do have some photos I wanted to share. I don't suppose they are anything particularly special, but please excuse my excitement over my new toy!:)
As always, thank you for looking and I hope you like them.
First three were taken with the 18-135 WR. (Really like the bokeh of this lens)

I had exactly the same problem with my K20d. I got it replaced, they said it was a faulty sensor. I also tried different SD cards.
It was only clearly visible on some photos but I could see them faintly by pixel peeping on almost all photos. If I remember it right it appeared more often if I used D-Range. (is it called that, can't remember)
I would not be too happy if I were you anyway and would definitely try to return it.
But if it doesīt show that much and often maybe it isnīt a big deal...
hope it works out for you!

The extra effort is vastly over-stated. Using Aperture, at the beginning of a sequence I use one of my presets, whichever one gets close. I just click down the list and pick the closest one. Then I make the final changes. Before I start the individual controls, if the number of changes is different from my normal presets, I save them as a preset. I use that preset for the rest of the pictures. Or if I don't think I'll use it again I save the changes and apply them without saving them asa a preset.
FOr example my BIrds preset, has fairly heavy setting on definition and contrast to bring up feather detail, as well as sharpening, saturation, and edge sharpening. So not only are those setting automatically applied. The slider bars are in my adjustment menu for fine tuning. I have presets for fall colours, for boosting shadows, etc.
SO really, I apply a preset, then do a couple of fine tuning adjustments, use the spot tools for problem areas. Usually it doesn't take me more than two or 3 minutes per image at the most. Many times I go out and shoot 200-399 images and spend less than 2 hours processing. For a "roll of film" 36 shots, less than 20 minutes.
You simply cannot get the most out of your images without spot controls, and that was also true in film. You have to dodge, burn, etc, and nothing messes that up worse than trying to do that on a jpeg. Nothing feels worse than when I have an image good enough to sell shot on a point and shoot and realizing that if everything isn't just perfect, I'm probably not going to get it to the "next level".
Jpegs are like polaroids. They give you an impression, and every now and then you see a really good one. Most of the time, you just see hints of the picture you could have had. But hey, I seen people with their fridges covered with polaroids. For some, an extra 5 minutes to work on a great image into a magnificent image is too much. And really , if you have a young family , lots of kids to keep up with no time to breath forget about process pictures, just like polaroids, jpegs are a great thing.

Glad to hear that they have already been added to the database. I am looking forward to seeing how the 50/1.8 handles, if it is anything like the 35/2.4 it will be a real bargain.

The uneven sky color is the effect of the polarizer, not the lens. The effect is maximum at 90 degrees from the sun (in any direction), and minimum when lined up with the sun (0 or 180 degrees). Wide angles cover a very large angle of view, so it is more or less impossible to avoid.
I personally like the effect, but since you don't, take off the polarizer.

Here's an experiment in post processing. A bit of a blown out look but I think I like it. She did.
Lit with a home made beauty dish at 11 o'clock.
Let me know what you think. Do you like the photograph? No, I will not post the original. She'd kill me haha. Just look at this and spill the beans.

Hi Tim,
The K-7 is a very different camera in many respects.
I've had the K10D, K-7 and K-5, sold the K10D 6 months ago.
To answer your question: YES. The K-7 dust removal system is extremely effective, much more so if compared to the K10D.
I've cleaned my K10D many times, rocket blower, wet swipes etc.
An occasional blow into the K-7 once a year to get the dust out is all I've ever done.
What I do not understand is that it is the *only* improvement that matters to you...
You'll get a *lot more* camera:
- Much better, larger display
- In camera level indicator, you never had that, so you don't miss it (oh, how I like that feature!!)
- Lens calibration (need debug mode in K10D), makes your pictures more sharp
- In camera lens correction (makes it slow though)
- A much better, faster, AF system, including a AF support light.
- More resolution
- Lighter camera, with better grip
- HDR, digital filters
- Better ergonomic (takes some use to time)
- .. all the things I forgot to mention
Get the K-7 and you will not be disappointed.
- Bert
