My ND grads were not far off that...
...and I still don't use 'em with the K5
Matt

I haven't used an ND grad in a long while
Not since the K5 and 14 bit RAW + Lightroom

But interesting idea - wonder how it will handle that in the output stage?

This thread may help

I've seen 'mashups' with the radio flash receivers wired into the remote so you can press the transmitter to take a shot. IIRC, the Yonguo flash triggers feature this already.

Correct - as far as image is concerned. But...

AFAIK, the Pentax Camera Utility does apply the in-camera settings automatically to the RAW

Pentax have built a very close link between the camera settings and the RAW converter. Others cannot easily match this since they have to cope with a myriad of different cameras and models, and not all embedded EXIF information (like the custom manufacturer data) is not public knowledge

It works like this - the camera records a TON of data about the shot and settings. Most RAW converters will take the basic cues from this EXIF data (like lens type, ISO, etc) to make automatic adjustments. Some of this EXIF data is Pentax-specific and difficult to work out what it means (unless you are Pentax ). So... Pentax's RAW converter takes a look at the full EXIF data and models itself as closely as possible to the camera settings as a starting point - and that's where you'll get the most consistent colour rendition between RAW and JPG (but not necessarily the most flexible work flow or creative options).

Lightroom is very nearly automatic - if you have a lens that's been profiled - but any extra CA (like the more difficult axial CA) needs to be done manually... but it takes 2 seconds.

Personally, I'd set up a test scenario: wide angle, backlit fine detail on the edges (like trees) and push a shot so that CA is obvious. Then shoot with and without CA adjustment in camera. Bring the two RAW files into Google Picasa (it's free and doesn't do CA adjustment), and into the Pentax supplied RAW converter - and pixel peep to work out which has CA adjustment applied

Have NT and EH... but there's not so much EH stuff around the south coast (but Dover castle pretty much makes up for it - a couple of visits a year for the family breaks even).

Always use NT for travelling too. We work out the closest NT restaurant and stop off for a bit to eat and a quick visit en route

Matt

Just a thought off the top of my head...

Perhaps it wouldn't be a bad idea to have a camera colour profile specifically for IR?
Not sure if anyone's done one, but there's no reason why the camera profile can't yank everything into the world of grey-scale, or at least some kind of decent range for working with colour (and then the B&W conversion).

Just worth adding this point:

When shooting RAW, it is only the embedded JPG image that is processed. As mentioned the RAW is just that.

It can be useful to know this - you can use in-camera options (like processing style, lens correction etc) and have that applied to the embedded JPG. There are a few free tools that will extract this JPG from the innards of the RAW file

But it can be equally frustrating, as sometimes the camera can get it more "right" than the RAW processing tool does! Many RAW processing tools will show this embedded JPG first, before handling its own internal RAW processing - e.g. Google Picasa. It's good to have a camera 'reference' that can be called on though - even if you haven't shot RAW+JPG

Also, as stated, Lightroom 4.1 has utterly astounding CA corrections! For example, the DA*16-50 can show some serious axial (longitudinal) CA when shooting wider than f/4 (so you get purple fringe near focus and green fringe far focus) - LR4.1 can completely resolve these issues! Other bright lenses can pop up purple fringing at wide apertures too (e.g. FA50/1.4, etc) Transverse (lateral) CA can be fixed in camera, and is common on the corners of very wide angle lenses - showing itself often as blue/yellow fringing either side of highlighted edges.

Given that LR4 is now greatly reduced in price (LR3 was around £225, LR4 is now around £91 new) it's definitely worth considering

Matt

The Historic Inflation Calculator is quite fun to compare these prices to today

Charlotte - which firmware version?

I know that the majority of 1.13 users won't have a problem. I really want to collate which firmware is running on the cameras that have this problem. I don't believe it's battery related, and am not at all sure that it's a hardware fault. I'm looking for some evidence for this mirror issue occurring either only in 1.13 or in other versions too

Matt

Peter - are you saying that you do have trouble with a K5 now yourself?

If anyone has the same issue, could you let me know what firmware version you are running?
I am running 1.13 - and wonder if somehow the batch of firmware released on 2012-03-01 is the issue (because I've never seen this on any other Pentax, and didn't see this before on the K5)
