Thanks Christian. I was in an auction for a Tokina SZ-X last night but then couldn't get to my computer in time for the auction ending. And it went for under 20, which seems like a giveaway price judging by your samples. Once again, I should have used autobid but didn't. How many auctions will I have to lose before I ever learn?

With yesterday being Remembrance Day, I spent some time looking at family photos from the early 20th Century (as I'm sure many did). Leaving aside the matter of B&W vs Colour, I'd say that my great-grandparents were taking photos a hundred years ago that were technically at least as good as, and often better than, the ones that most of family are taking today with their smartphones.

And of course that's because every frame that my great-grandparents shot cost them money, and they weren't particularly well-off people, so taking a photo was an event and they made a real effort to do it well. The main reason why most of the smartphone photos that people take today are so bad isn't the fault of the phone technology itself, but because they take so many photos so casually that they just don't make any effort at it. Presumably people who invest in a "proper" digital camera are more likely to make a bit more effort, resulting in hopefully better photos.

One thing's for sure, I think that my great-grandfather's hundred-year-old folding camera loaded with a high quality modern film could still give any smartphone and many DSLRs a pretty good run for its money in the right hands.

As you say (and I agree) aesthetics always comes down to a matter of personal preference, but I can't personally see how the choice of resolution in a print can ever be anything other than an aesthetic decision.

(Talking about what an advertising and commercial professional would do is an argument from authority and a straw man at the same time. Darn, those straw men can get authoritative if you let them. :lol:)

The part I don't understand is why anyone would ever look at a photographic print from ten inches away. When there is a lot going on in a photo that viewers need to be able to make out in detail, that photo is usually printed big enough that the detail can be seen from a comfortable viewing distance. Would anyone ever really make a print in the belief that the ideal viewing distance for it is ten inches? Apart from the sort of gear-obsessed photographer who only takes photos of brick walls and test charts?

Setting up HDD for reliable read/write access from both Windows 10 and Ubuntu / Mint?

I've been dual booting Windows 7 and Ubuntu for a few years with the shared drive formatted to NTFS, and both operating systems have handled it okay. In fact, I've actually had more problems dual booting Windows 7 and Windows 10 causing a frequent need to run CHKDSK.

The main thing to watch out for is that Linux allows longer file names than Windows, which can be hassle. You have to then extract the 8 character file name from the Windows command line, and I once lost a file when that failed.

Centuries before photography was invented artists had already realised that people tend to look at any image from a distance roughly equivalent to the diagonal of the frame. The great masters relied on that to get their perspective effects. You mention that the human eye can only resolve about 170 ppi at 20", and 20" is close to the diagonal of a 12"x18" print, so in the real world even a print from a 6 MP camera made at 150 dpi (or upsampled to 300dpi) comes close to the limit of what most viewers can resolve a normal viewing distance. And funnily enough I've got several 12"x18" prints on my walls shot with 6 MP cameras, and nobody, not even other photographers, has ever mentioned any lack of detail.

I think that a photograph deliberately intended to be seen bit-by-bit in close up would have to be printed at a size large enough that it doesn't really give viewers much chance to get far enough back to see it from the diagonal distance. I suppose Andreas Gursky is the obvious example of that approach. With a 15 foot wide print there seems to be an instinct to move in closer to look at the details, while with smaller prints the tendency is to stand at a distance where you can take in the whole. The reason why Gursky's photographs look like nothing much on a computer screen is that they were never intended to be viewed that way.

Which raises the obvious question: At what size does a print make that transition from being seen to its best as a whole, to being seen at its best as an assemblage of close-up details?

It looks like a movie I'll definitely want to see if it's coming to my part of the world. I think the therapeutic value of photography is something that deserves some serious study and consideration as a treatment. My personal feeling is that being able to capture the world with a film or digital camera, and to make it look the way we want it to look, can give us back a sense of control that we might have lost in some other part of our lives. It's certainly what photography has done for me when things have been rough.

Perhaps you could clarify? You seem to be using the terms "resolution" and "image quality" as if they mean the same thing. My point is that aesthetics, which you seem to want to put aside, is a fundamental part of image quality as that term would be understood by most people in the real world.:)

Aesthetics is (are?) the only thing that matters when it comes to making a print. To equate resolution with "image quality" and to claim that this "IQ" is the most important factor in a print is completely to miss the point of why real people in the real world like to look at photographs.

It's really best to use a lab that provides profiles that you can download for soft proofing. A good lab should provide profiles for each paper type they offer, and soft proofing then uploading your file with the correct profile embedded means that what you see on your screen will be a very good match to the final print.

Wonderful shots of a car that gives me pure joy every time I see one. And thanks especially for the shot showing the rear door mechanism. I remember being endlessly fascinated by the beautiful simplicity of it as a kid, and I got exactly that same feeling again when I saw that photo. It's the same feeling I get when I'm working on one of my Takumars: that sense of the pure rightness of how each component is designed to do just the thing it has to do, and does it beautifully. A feeling that I never get from modern day plastics and electronics.

I'm not sure exactly how much of a hopeless geek that makes me, but probably quite a lot of one. :)

It has to be the original E30 BMW M3. I used to own the lowly E30 316 way back when, and the handling was just a joy. So you can keep your 911 if you want it, but I'll take the old Beemer thanks.:)

At first I thought the lighter parts were wood, but then I realised that it was just painted to look like that. There's something about a wooden-framed car that I've always loved, perhaps because of so many happy memories of my mother's old Morris Traveller from waaaay back in the early seventies.

Great results with the 16-45 again.

As others have pointed out, the K10D is well out of date in terms of resolution, ISO performance and speed of operation. It has developed a cult reputation because of its unique rendering style, particularly its colour rendering, that you can really only get from that 10MP CCD sensor. We've got quite a few members here on the forum who own much more recent cameras, including the K-1, but who still use the K10D when they want that indefinable CCD something.

My usual suggestion is to hang onto the K10D no matter which of the more recent cameras you decide to go for. You won't get much for your K10D if you sell it, and there will be days when you'll want to enjoy that unique rendering style again for old time's sake. :)

I use Flickr purely as a place to host photos for posting here, and I expect it'll take me a few more years to get anywhere near 1000.

And call me pernickety, but I'd never switch to a Flickr "Pro" account simply because it's called a "Pro" account. I absolutely refuse to ever own or use anything with words like "Pro" or "Executive" or "Exclusive" on it. So I'm glad PF uses the nicely neutral "Site Supporter", because the site never would have got a penny out of me if the word "Pro" had been involved. And let's face it, the number of actual professional photographers on Flickr is a miniscule percentage of the "Pro" accounts.

There's nothing more amateurish than a thing that says "Pro" on it. :)

Small size "always with me camera" - any tips?

I've always thought a Leica X or X2 with a clip-on optical viewfinder would make a great always-with-me camera. And used prices are very reasonable now, certainly less than a new Fuji X100F.

But in the real world I use the Pentax K-S1 with either my Takumar 24mm/3.5 or 28mm/3.5. It's a great little camera, and while it's not pocket-sized I can easily carry it around on a wrist strap all day. If f/2.0 is essential, you could combine it with the Kiron 28m/2.0, which I've owned in the past and can confirm is a really excellent lens that I never should have sold.

I've used the DNG converter to convert raw files from 6MP cameras that only offer PEF into DNG files to create custom profiles using Adobe Profile Editor. They work fine for that purpose, and the resulting profiles work directly on PEF files in Camera Raw without any need to do an intermediate PEF to DNG conversion for each shot. As you'd expect them to, since of course PEF and DNG are just the same candy in different wrappers. :)

Thanks Tim. The F100-300mm that I've been using is f/5.6 at 300mm and I've been able to manually focus it fine (and certainly more accurately than autofocus manages). So I'm hoping that the extra half stop to f/6.3 won't be a problem with the Tak. I'd certainly go for the f/4 version if one happens to turn up at a bargain price -- maybe a fungus infected one that I can buy cheap and clean up. But the f/4 seems to usually go for about three times the price of the f6.3, and at the moment that's a major factor for me.

But who knows, maybe in a few months my health will have picked up again and I'll have more cash coming in to feed my photography addiction. :)
