Was: Does this mean what I think it means? Lets back up a bit here. You have a sensor that has an analog out put. You send that output to an analog to digital converter. The converter produces an 8, or 10, or 12, or in this case 22 bit digital representation of the analog signal. Then that digital representation is processed digitally. Note that the analog signal does not change. The only difference is that the higher bit rates produce a more accurate representation of the analog signal. There is no magic here, just technology. Rephrasing that, the analog signal is simply broken up into more digital pieces, nothing is added to it. -- graywolf http://www.graywolfphoto.com http://webpages.charter.net/graywolf Idiot Proof == Expert Proof Hi, I did not say the digital processing would add anything else than noise! If you look closely at the if part: Yes, it has to decide the exposure time and f-stop but *IF* the imaging *AND* image processing has a really wide dynamic range you can still choose the correctly exposed part of that range (choose the most fitting 12 bits space from the full 22 bit space for example). With *imaging* I mean the sensor and with *image processing* I mean the analog amplifier stage and the a/d conversion. Sorry for maybe not being very clear (English not my first language). In another e-mail to this thread I already said this was going into a bit too technical (and theoretical). I know there is no magic in the electronics design (I do it at work) but sometimes I sure feel like a magician... At least in theory (and I am sure we will see that partly in practice with the K10D), using a higher bit depth in the a/d stage is a really good thing to do.

RE: It is ingenious! Was: Does this mean what I think it means?
I think the actual sensors do have the 14-16 bits you mention - which literally means that the max charge is up to some 65000 electrons. However, they also have a readout noise of at least 10 electrons, which is equivalent to 3 or 4 bits. This essentially means that you are left with a usable dynamic range or latitude equivalent to 12 bits; any additional bits would just be measuring the noise, if they contained any information at all. That's why a 12-bit A/D is traditionally used. Furthermore, when you amplify the signal for a higher ISO setting, you also amplify the noise, thus shifting up the 3 or 4 bits so that contain noise, so it enters even the 12 bits you keep. But like I said, this has been discussed a lot in the past few weeks. In in several rounds before that, too. Enough for now. I'm not sure I've read the data sheets of the *exact* sensors used in the Pentax cameras, either, by the way (I've seen technical data for various ones of similar type...) - Toralf Hi, Yes, actually I was talking about usable bits, taking the noise into account, thus giving 14-16bits of usable data. This is so at least with the good quality astronomical ccd sensors but I am sure the DSLR camera sensors are coming close nowadays (or am I just hoping?). In any case, when designing measuring systems (using amplifiers and a/d converters) it is a good thing to have plenty of more bits and precision compared to the original signal. This way you will minimize the added noise. When having a 22 bits a/d converter on the K10D you can also measure and analyze the noise of the low expusure pixels. You will get all the available information out of the sensor.

A question to you, digital pundits, should I mass convert my PEFs to DNGs for archival or should I retain the PEFs?

They aren't staying with 6, they've just introduced a 10 megapixel camera. We're seeing DSLR's stratify into two tiers - 6 megapixels, like te K100D, and 10 megapixels, like the K10D.

Antti-Pekka Virjonen wrote: I think the actual sensors do have the 14-16 bits you mention - [ ... ] Hi, Yes, actually I was talking about usable bits, taking the noise into account, thus giving 14-16bits of usable data. This is so at least with the good quality astronomical ccd sensors but I am sure the DSLR camera sensors are coming close nowadays (or am I just hoping?). As has also been mentioned many times, the max. charge or full-well capacity of the sensor depends directly on the pixel area. Apparently it's approximately 1000 electrons per square micrometer in a normal CCD I'm not sure about astronomical sensors, but in the linear CCDs I've used at work, the pixels are 12x12 or 14x14 micrometers, which should give you 2-3 times the data required for 16 bits. That may not be quite enough to leave you with 16 good bits after you've thrown away the noise, but 14 should be no problem. On a DSLR, on the other hand, the pixel size has been something like 8x8 microns for a while now, but on the latest (10MP) cameras, it's down to 6x6 or so. In other words, the DSLRs cameras are not coming close; they are actually moving further away in that the pixels keep getting smaller! A different side of this is obviously the noise situation. You can also improve the number of usable bits by reducing the noise, and this is an area where the DLSRs probably are getting better - but they also have to, in order to compensate for the smaller pixels. And it wouldn't surprise me if the astronomical sensors have very low noise, too. In any case, when designing measuring systems (using amplifiers and a/d converters) it is a good thing to have plenty of more bits and precision compared to the original signal. This way you will minimize the added noise. When having a 22 bits a/d converter on the K10D you can also measure and analyze the noise of the low expusure pixels. You will get all the available information out of the sensor. Yes. It definitely seems like I good thing to keep *all* the info for the early image processing stages. Also, having some extra bits around will minimise round-off errors that might accumulate across multiple pixel value adjustment steps. You may think of extra bits as more decimals in intermediate results. I think this may be the most important consideration behind the choice of 22 bits. - Toralf -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

RE: It is ingenious! Was: Does this mean what I think it means?
Toralf, I think you got it all just right and I believe we were both talking about the same thing in the first place :-). Sometimes it just takes a lot of writing when trying to describe not so easy things. I have to admit I wasn't looking too deep into the DSLR ccd data sheets when trying to figure out why they chose 22 bits. Plus, it is not very easy to get the bare foot data from the current sheets, since the ccd manufacturers seem to be hiding the basic facts to get more of their sensors sold (?). Astronomical sensors generally have quite big pixel sizes (but there are quite small as well, comparable to DSLR). The smaller the wells, the higher the noise (because of the smaller area to capture photons and smaller space to store electrons. Making better signal processing stages is one way (maybe the only one at this time) to improve the results. Pentax seems to be ahead of the competition with the new (to DSLR world) approach when using better designed signal processing. Let us hope there will also be better sensors in the future :-). Actually the only negative thing I have with the K10D is I hoped they would incorporate a full frame sensor to get more sensitivity and lower noise (more exposure latitude). But maybe it would have competed with their coming 645D too much. BTW I did preorder my K10D today! It will be exciting to see the sample photos of production model K10D. I think what we will see is a little different digital pictures (closer to film kind of images). But I have been proven wrong before...

Getting a bit of an Ah-Ha from that skim, apparently folks are talking about electrons and holes as if they are the same thing. They definately are not. A hole is a space that can accept an electron, and if we are talking about 40K or so holes in the photodiode then that makes sense as that would be the amount of additional free electrons that the diode can accept (note that lots of them will bounce around and never find a hole to fit into). Still in the real world sense the output can not be considered stepped but a fairly smooth analog curve. Sometimes we try to apply too much to our understanding of things. For those of you who insist that quantum mechanics apply at the real world level, please send me a quart of quantum foam, I want to use it as a battery.

I'm bummed. Even though I know she's right. !! You gonna let her tell you what's what ?? You gonna let her wear the trousers ?? You gonna let her have the final say ?? Sure you are. But the key trick here is, confusion. Works a treat. Use dummy equipment and decoys to your advantage. Build up a collection of tat and old junk so she doesn't know what's coming or going. Then when the coast is clear, pounce. Go into covert operational mode. Delivery to work address only. Substitute items that look like each other. Stifle hysteria over new acquisitions until late at night with vodka. I've got so much stuff in and out that she can't tell what's coming or going. It's like a sleight of hand, only bigger. Values - nothing is as advertised. (Converted to US dollars for clarity) so anything around 50 bucks comes in at 25 or 30. This builds in room for human error which we all have to take into account. It's not lying - it's like traffic cops allow 10% on your speedo for error. It's just 'write-off' ergonomics. 500 bucks comes in at 'Oh a couple a hundred or so'. Once you get over a thousand, it gets more tricky, but can be done with some creative accounting. Always deduct any local taxes, postage, insurance, anything like that. Then of course there's the profit margin the manufacturer makes, that's got to come off. Before you know it, a $1200 camera can come in at gee, WAY under a grand, honey, and sound very palatable.

I was planning to get a Pentax digital camera and possibly use the tele lens from my Pentax film cameras but I thought I could crop more heavily with a higher number of MPs. I assume the photo quality must be good for Pentax to continue using 6 MP, but I thought cropping would be more limited with the 6 MP than with more MPs. Why is Pentax staying with the 6? -- Things should be made as simple as possible -- but no simpler. --Albert Einstein -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
Re: Cropping and MP count
Because they're going with a High-Low strategy. The 6mp camera is the budget model. The K10D is being released this month, with a 10mp sensor. That's the current high end. You've been partly misinformed. MikeM wrote: I have just read that Pentax have stuck with 6 MP for their K100D.

Re: K10D sensitivity?
Pentax is reportedly still finalizing the firmware as we speak -- Mark Roberts Photography Multimedia - Does anyone else find this worrisome? Since dealers have been given availability dates, Pentax's engineeers and code writers will be working under pressure to get everything finished. I'd prefer that Pentax take time to do it well, and ship later. Joe -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Re: Re: Re: PESO -- Ken is looking much healthier now
That looks pretty much what I got when I worked on your original image. If you go much further you'll be sacrificing the lighter details to the right of Ken.

Re: To (convert to) DNG or not to DNG
Pentax's own Photobrowser/Photolab 3 will do that now. I haven't tried it yet but then I don't have a reason to at this point. Boris Liberman wrote: Mark, How one does obtain PEF-DNG converter?
