HDR - High Dynamic Range / HDR with LR 4...
« on: September 22, 2012, 11:51:22 AM »
Highlights that you thought were unusable are easily rescued with Lightroom 4.

These three images are all from the same base image that I was going to use as part of a set of 5 for HDR because of problems with highlights.

The three images are - "from_camera.jpg" (this is the image imported into Lightroom, without any adjustments being applied). "lightroom_process_2010.jpg" is the best I could get with Lightroom v3.6. Maybe I could make it a bit better but going further requires messing around with tone curves and is quite tricky. Lastly, "lightroom_process_2012.jpg" is what I get with Lightroom 4.2

Of the three, it is the one from Lightroom 4.2 that looks the most natural and as can easily be seen, a lot of detail is recovered from the clouds whilst a little bit of saturation fills out the colours with some body.

Software & Accessories / Does LR4 do away with HDR for you?

I've been working with a bunch of images that I previously took for HDR purposes and I'm finding that with LR4 and "process 2012", I can normally work with one of the more over exposed images and achieve the look I want a lot easier. it's like earlier versions of Lightroom (and DPP too!) are hiding a lot of highlight detail.

What about others?

Canon General / Is it time for the "CEO" of Canon's DSLR division to resign?
« on: September 18, 2012, 08:06:32 AM »
The revealing of the 6D has got to be one of the biggest anticlimaxes in Canon's recent DSLR history. Never has a camera wasted so much potential to score well. If Canon were alone and the only manufacturer producing a cheaper DSLR then it would probably be doing better amongst the Internet forums but unfortunately for Canon, there is the Nikon D600, alongside which the 6D appears as a "huh?"

The 5D Mark III also suffered a lot, primarily because of the rise in price without a commensurate rise in IQ. Again, if you took away the Nikon D800, it doesn't appear too bad but again, there is nothing exciting about it.

Now that all of Canon's cards are on the table for this year, you're left wondering what were they thinking? That Nikon and Sony would just stand by and not enter the market? Or did Canon simply underestimate what they've been able to do in CMOS sensor development?

The 1DX is out there by itself. It is a remarkable piece of equipment, tailor made for its target audience. And perhaps that's where Canon's problem is: it doesn't really know who the audience is for the 5D3 and 6D. Why wouldn't it know that? Because so many people bought the 5D Mark II, it became impossible for Canon to understand all the details of who was using it, how and why.

Thus the success of the 5D Mark II may have actually killed Canon in multiple ways. First they've become complacent because they've thought they could just tweak it a little here and a little there, increase the price and everyone would fall over themselves in love. That hasn't happened, in part because of the price and in part because it was just tweaking. In the second, as above, the camera has had such wide appeal that it became impossible for them to fully grasp why it succeeded and thus they didn't know how to repeat that success. This is likely just an accident of history as much as anything else. Thirdly, in not knowing who to listen to or why the 5D Mark II was such a success, they've ended up listening to the wrong folks about what camera Canon would need to succeed.

Thus given what the 5D3 and 6D have revealed to be, I think that the only option for Canon is remove the people who made the final decisions about which features should be in/out and the price for the camera. I think it is more than evident that they targets for both cameras simply wasn't high enough and thus Canon has underperformed.

Third Party Manufacturers / New Pentax K-5 IIs - no AA filter!
« on: September 11, 2012, 07:48:35 AM »
Another manufacturer is now offering a DSLR without the low-pass AA filter - Pentax.

Nikon was first with the D800e and now Pentax with the K-5 IIs.

Will Canon offer us the option?

Lenses / New: Canon CN-E15.5-37mm T2.8 L S/SP
« on: August 29, 2012, 08:29:09 AM »
Along with the C100, Canon has announced a new wide angle lens that comes in at 15.5-47mm.

Now that's a lens I could really do with on a DSLR!

Except that at $24,500, it's a bit out of my reach.

Canon, why can't you give us a photography version of this lens?
With autofocus and no (or very little) field curvature?

EOS Bodies - For Stills / 5D3 - AFMA similar to 5D2 or 1DX?
« on: August 17, 2012, 08:51:11 AM »
Does the AFMA in the 5D3 work in a similar fashion to that of the 5D2 (one setting per lens) or does it work like that of the 1DX where it is possible to have two settings for zoom lenses?

From a local newspaper:

Verdict: This is a wonderful camera. If you hvae Canon lenses and want to move into the blissful realm of full-frame capture, then the 5D Mk III is for you. But the MkII is just as good for stills and costs $1600 less. If you already have a 5D Mk II (as we do), there is no pressing reason to upgrade. If you are starting from scratch with nothing invested in lenses and accessories, then look at the Nikon D800. It has superior ergonomics, a more luxurious feel and higher resolution sensor, and produces uncompressed video. And it is several hundred dollars cheaper.[/u]

This guy uses the raw sensor data from DxO (remember, they're worthless!) to create some different measurements:


ModelQEMin Read Noise (e-)Max Saturation capacity (e-)

This table also makes the 60D better than the 50D and 7D.

Third Party Manufacturers / 41MP Nokia PureView Reviewed

Page 4 with the interview with the Head of Imaging Resources at Nokia is very enlightening.


EOS Bodies / New, cheaper, Canon FF DSLR... 70D?
« on: July 21, 2012, 12:13:00 AM »
Given that Canon seem to be putting APS-C into the EOS M cameras, why wouldn't they be just a bit more aggressive and make the 70D full frame?

Sure, if it debuts at $1999, it is vastly more expensive than what the 60D is today, but over time we should see prices drop.

It also solves the problem of which "digit" to use for the camera in the 6-9 numbering scale.

Lenses / Why did Canon release the 40/2.8 pancake before the A1?
« on: July 20, 2012, 07:50:41 AM »
Any thoughts as to why Canon released the 40/2.8 pancake so far ahead of its mirrorless offering?

Lenses / Are these new lenses expected to be sold for 15-20 years?
« on: July 17, 2012, 09:16:30 PM »
When we look at some of Canon's current lenses, such as the 50/1.4, we can see that they either are or are approaching being 20 years old and that their price hasn't changed a whole lot in that time. However in the last 20 years, lots of other things have had rather dramatic price changes, for example houses and cards and last but not least, wages have gone up.

What that makes me wonder is in 10 or 15 years time, will the prices of these new primes with IS still be considered to be "high" or will they have moderated if the price stays the same but our take home salary has increased?

Is Canon delivering new lenses at a higher price with the expectation that they will remain on sale for close to 20 years and that if the price doesn't change then as they approach end-of-life, they will have become as affordable as the current lenses are today?

Is an $800 lens today a $400 lens (in terms of affordability) in 20 years?

Something that I just realised is that Canon have to replace or retire a lens within 26 years of its first manufacturing date as their date code system does not have a way to handle it wrapping.

Looks like Canon think that recycling the 5D Mark II's sensor technology continues to make sense.


The technology in that sensor is approaching 4 years old now. Isn't it past time for something better?

Something with less read noise?

Something that is free of banding?
