1Ds Mark IV & 3 Lenses in August?

[unruled]

thanks for the cost clarification posts. puts things into perspective for me.

"Lightroom might choke......"

Considering LR struggles with even very small files because of the resource hog it is, I would tend to agree. However that's more of an issue for the software designers rather than a problem with the computer or high pixel count image files.

I've always considered good computer code as code that manages to achieve the object using as little computer effort as possible. LR seems to have been written by people who think otherwise.

LR is so incredibly slow for me, its unbelievable. As much as the UI on DPP sucks (as does the workflow), performance just seems easily 3x faster in it. Ive actually started doing initial sorting (ratings, removal flags) in DPP now, and then I import to LR after that.. just cuz its so much faster that way.

Generating thumbnails is just a problem for LR. Ive set LR to use lower quality thumbnails in hopes to speed it up, but not much result. DPP has higher quality thumbnails and its fast. Its a mystery why LR couldnt do that.

unruled,

Apart from higher MP for smoother images, my own interests lie in the dynamic range and low ISO performance, which must be best in class by some margin. I have no interest in the higher, noisier ISO's already offered on existing bodies and certainly don't need even more.

I don't want to be rude here, but don't you realise that dynamic range is the difference between clipping (255) and the noise floor. The better the noise supression the better the dynamic range, the two are inextricably linked.

Considering all the things that LR does, storing absolutely every edit in it's db as well as all the metadata capabilities, I consider it resource intensive but not a hog. It NEEDS ram and a fast disk and I expect no less. I own both CS5 and LR3 and I have no problem running both simultaneously on either my laptop or my desktop. To get LR to perform, make sure you max out available RAM, I have 8GB in my laptop & 16GB in my desktop. Put your catalog(s) on an SSD and store your raw files on separate 7200 RPM HD, the larger cache available on the more expensive HDs is definitely helpful. While I have a RAID config on my desktop, I don't find it absolutely necessary to get great performance out of LR.

My own judgement of dynamic range is a whole lot worse than that! I am not bothered about scientific lab tests, just a practical rule of thumb measurement. So I judge DR as the number of stops in a printed image from paper white to as close to full black as my R2880 will go, this is typically less than half the DR as measured using noise as the limit. So using my method, noise is not a consideration in DR.

So where the lab tests might claim 12 or more stops using the noise floor, I would argue that 5 or at the most 6 stops really represents the current state of the art. Give me 12 "real" stops and I'd be a very happy man.

DR is one area where digital still lags film, by some margin.

You should be on a Mac, no problems here even with multiple P65 (PhaseOne 65mp back) files in Capture on or Canon files in Photoshop.

yeah aperture only on mac. I am using one. I have an overclock mac with 4Ghz quad processor and 12GB of RAM. Except your disk are faster. I did not bother with RAID.

I do have a small SSD for my primary drive, but images are stored on a ordinary $60.00 1 TB drive.

It did not work for me, because in OSX must store all program in SSD, i have a lot of program, my old SSD cannot fit in all program. I gave up and just run everything on normal HDD.

By small, I mean 120GB. They are available often for $100, and easily hold all my software plus Windows 7 64 bit.

I have a TB of images, so I use a separate drive for those.

got this from another camera site :

National Geographic photographer Stephen Alvarez has posted on his blog that “[a] friend told me that there are some Canon 1ds MK IV test models floating around. That means 2 things. The much awaited camera’s release is imminent and we should have a first look at it here soon.”
We’ve been expecting the Canon flagship to appear, and the first sightings are being reported.
As noted previously, expect the Canon 1Ds MK IV to be 30 megapixels or more, possibly as high as 40 megapixels (although I think 30 to 32 is where it’ll come in at).
The big unknown on the Canon flagship is video. I’m thinking not, due to technical constraints with such a large sensor and the amount of information that it would need to pipe through for video, but you never know. Canon may surprise us.
Expect the 1Ds MkIV to have the 1D MkIV focus system. That’s pretty much a given.
It’ll be interesting to see the full official specs on the flagship, and if anybody has anymore sightings to report, let me know!

Local photographers have been seen with test models of the 1DSMK IV for over two years. It does not really mean much, except that they are testing.

when i bought my 60GB SSD it was high capacity then, now i can buy a 200GB one at same price.
i gave up 60GB SSD for osx, but it work with win7, because win can use other partition easily, not so osx.

so high, it must be very expensive, because yield will be low.
and i doubt there is any PC or mac that can work with the RAW file on aperture 3 smoothly.

I might have to wait for end of year, when intel come out with new chips and raid on fastest ssd available to even stand a chance. CMOS chip is moving faster than PC technology.

Why do you think the yield will be low? If there is a flaw on the sensor, its no good, regardless of the number of photosites. The yield, given the same quality of wafer is mostly affected by the size of the sensor.

I don't get it?! If the sensor gives you 12 stops and the print only 6, why is this a problem of the digital part?

The problem is not the printer or the paper. Yes they have their own limitations but the camera sensor is the major stumbling block.

When the labs test DR they look for "information content" in the highlights and shadows and as long as there is information its counted as valid. The problem is that at the shadow end its pure noise, nothing else exists, yet the tests ignore that inconvenient fact. The problem exists because science rather than the mark one eyeball is used.

Now consider the response curve of any digital camera sensor you care to name. Typically in the middle there is a curve that approximates the curves we are used to seeing with film. However at either end there are enormously long tails that are virtually horizontal stretching maybe 3 or even 4 stops in each direction, serving no useful function except to fool the lab tests I am being so scathing about!

So I repeat, 6 stops is a typical "real" response from digital cameras right now and I for one look forward to Canon improving on that. I have a very nice iron footbridge over a river near me and on a bright summers day I can get less than half the tonal range of the scene in one shot. I tend not to like over the top HDR images, but often shoot at least 3 bracketed frames and pick and choose the best from each. But I'm hoping that in future we will be able to do it with one frame.

Richard/Motorhead,

This is totally off topic but I saw pictures on your Zenfolio from Provence. We're going there at the end of September, so I'm looking for tips/suggestions. Flying into Nice, driving to the Canyon du Verdon then to St. Remy de Provence, where we are renting an apt. for a week.

I'd love to channel Cartier-Bresson and get an iconic shot of the Plane Trees. Any location ideas? Also hoping to visit the Camargue. Plus, of course, the cities and villages themselves.

Any thoughts?

Sorry guys for veering totally off-topic, but as we all know, hardly any of these threads stay on-topic anyway.

unfocused,

We based ourselves in Avignon with the intention of catching the sunflowers and lavender. Sadly both were early that year and we pretty much missed both. But Avignon is convenient to get to by train and a good base for your work I'd say.

Cannot remember too many plane trees, but the main square in Avignon has a number from memory.

Motorhead/Richard,

Thanks. I appreciate your response. BTW, as a regular reader of this forum, I also appreciate the reasonable and commonsense approach that comes through on your posts.
