Leica M8 and M9 DNG Profiles for all

March 1st, 2011

Yes, I know I haven’t updated this site for a while, but that is just because I was busy with other projects. Since there is a lot interest with the Leica M8 for Nikon cameras preset I did a while back, I thought it’s a good idea to update that the real thing is now available. I finally had some time to create Leica M8 and M9 DNG profiles for other cameras. This means that you can get Leica M8 colors right on your Nikon, Canon, Sony, etc…

You can actually do a lot more. You can mix between platforms, you can get Nikon colors on Canon cameras or Canon colors on Sony cameras and so on…

Check out this page for more information.

Edge-Preserving Decompositions

May 2nd, 2009

Local toning algorithms are becoming very popular among photographers. We all grown to love Lightroom’s clarity tool, which basically preforms local contrast operations on the image. A new paper suggests using Edge-Preserving Decompositions for Multi-Scale Tone and Detail Manipulation, which may bring new possibilities for image processing operations such as clarity, USM, DRC and even HDR. I really liked the tone manipulation method results as shown on the researches web site. I think it will allow me to get very interesting photographic results. Maybe some of this will be implemented in a photographic tool someday so we can enjoy it. Click here for Edge-Preserving Decompositions for Multi-Scale Tone and Detail Manipulation.

Lightroom Preset: Leica M8 Colors with your Nikon

March 26th, 2008

A few weeks ago a kammagamma reader asked me if it is possible to set Adobe Lightroom to mimic his Leica M8 colors with Nikon D3 RAW files. For those of you who don’t own a Leica M8 rangefinder, Leica M8 captures DNG files with gamma and color settings that were designed by Leica. So when opening Leica M8 DNG files in Lightroom or ACR, a “Leica” color look is being applied to the images. Long story short, it’s rather simple to mimic those setting with lightroom for Nikon cameras and I think most of you might find this preset interesting.

I’ve tested this preset with some Canon cameras and it was quite close (although in theory it should be the same), but there is more accuracy with Nikon D3/D300 cameras. If there is going to be demand for this preset I’ll try to produce a more accurate Canon version. Please do let me know how this preset works for you.

New top story, Nikon D300.

December 10th, 2007

We have a new top story today! We wanted to test how much of an improvement is the new Nikon D300 over the Nikon D200. We tested the Nikon D300 for true sensor RAW Dynamic Range, SNR and noise reduction on JPEG files. All in our new top story.

Nikon D300, how much of an improvement?

We were curious to see what improvements there are in the Nikon D300 compared to the Nikon D200. To find out we performed a few simple tests. Almost all of the tests you are about to see were done on the actual RAW file using Matlab. This means that there is no image processing involved […]

New article, High ISO with DPP.

November 29th, 2007

We are back from a slight break with a new article! This one is about Canon DPP and High ISO images. As you know, we are quite pleased with Canon’s JPEG noise reduction performance. Sadly though, the same excellent level of noise reduction is not what you’ll find with DPP. There are some tricks you can do to produce better results, but it is really up to Canon to address these issues. Click here for “High ISO with DPP should and can be better”.

High ISO with DPP should and can be better

We have already established that Canon’s current noise reduction system is excellent. However, you can only take advantage of the new system by using JPEGs produced internally by the camera (As of today the EOS 40D, the EOS 1D Mark III and the EOS 1Ds Mark III are using Canon’s new noise reduction system). Many […]

iPhone’s screen gamut is quite good

October 13th, 2007

I had to get me one of those iPhones. It really is that good as they say. During some sneaking inside the iPhone I have discovered the ICC profile for the screen the iPhone is using. It is really amazing that the iPhone actually uses an ICC profile, but even more amazing is that its screen is quite good. Its gamut range is very close or in even better in some cases than the old non LED LCD screen of my MacBook Pro. Not bad at all, you can find some comparisons here.

Finding focus for EOS 1D Mark III images

September 21st, 2007

I was analyzing some focus tracking test images I’ve done with the Canon EOS 1D Mark III a few weeks ago. To speed up things I need to come up with a simple tool to automatically find the most detailed and string edges in the image. The result is Focus Finder, a Photoshop droplet to find the focus point in your images.

See this page to download Focus Finder and for more details.

Just drag and drop any image on the droplet and Focus Finder will attempt to find the strongest most detailed part of the image. A red circle will mark the focus point. Focus […]

Top story: Leica M8 colors

September 2nd, 2007

We have a new top story today. In the new “Leica M8 colors” article we talk about how Leica has designed the color look of the JPEG images. We also looking into how different RAW solutions render the colors out of the Leica M8 DNG files. The results are very much subjective, but we also use some objective measurements to help you better understand the colors. Read the “Leica M8 colors” article.

Leica M8 Colors

Whenever you hear the word Leica, say the word Leica, or even think the word Leica, you think of quality. The quality of the product, the quality of the lenses, the quality of the image and surprisingly, also the quality of the colors. But why is it that when you think “Leica”, you think that […]

Phase One Capture One 4 beta is here!

August 30th, 2007

Finally, it’s here! Phase one just announced a free beta download of Capture One 4.0. The new version has some new editing tools, a new design and a very slick user interface. I have been a long time Capture One believer, mainly because the ICC support so I am very glad Capture One will soon be up to date with Aperture and Lightroom. The one thing that is very important to me is Image Quality, and version 4.0 seem to have a few improvements. From a first glance I think the Luma noise filter still needs quite a lot of work (Think beautiful grain Phase One!) and the Color LUT editor is now missing (Might appear on the Pro version?). Let’s hope for a quick final release. Download Capture One 4.0 Beta here.

Canon EOS 1D Mark III vs. Canon EOS 5D

August 26th, 2007

We have a new scene comparison today! As many readers requested we compared the new EOS 1D Mark III to the EOS 5D in our lab scene. You can find our Low ISO comparison here and our High ISO comparison here. There is a new feature in our High ISO comparison, we are now allowing you to switch between RGB view, Luma view and Chroma view. This will allow you to better understand how the camera maker has filtered the image. Very cool new feature.

Canon EOS 40D high ISO samples

August 25th, 2007 has some interesting high ISO samples of the Canon EOS 40D with NR set to ON and OFF. From those samples it looks like the EOS 40D can reduce noise in the same fashion as the EOS 1D Mark III, but we will have to test that ourselves to be sure.

New Nikon EXPEED image processor

August 25th, 2007

Nikon has announced the new Nikon D3 and Nikon D300. Both are very much similar in exception to course to the full frame sensor of the Nikon D3, a 12 MP CMOS sensor with a pixel pitch of 8.45µm! Both cameras now utilize Nikon’s new 16 bit image processor called EXPEED. It has some very interesting features, such as real time chromatic aberration correction and Active D-Lighting. For those of you who are not familiar with the D-Lighting technology, D-lighting can “light” the dark parts of the image by using a filter. This way the system will lighten pixels in depends to where the pixel is in the image. Also interesting to note is the new “Picture Control”, a unified color system for all Nikon Cameras. There are Standard, Neutral, Vivid and Monochrome Picture Control settings. Each can be tuned by the user and could be transferred to other cameras. This still not means Nikon uses color LUT that could be uploaded to the cameras as Canon does (And all of this is worthless if you use non Nikon of Canon Raw software). Nikon claims EXPEED is capable to produce the same image quality as Nikon Capture NX, which normally does produce excellent image quality – far better than the Camera. We’ll have to test EXPEED to see if it is true.

Update: Picture Style Editor, new details emerges!

August 21st, 2007, a Japanese website has new details on the Picture Style Editor. From the included screen shoot it looks like it has a color LUT editor!!! Finally you can create your own picture style profiles by transforming HSL values, something I have been wanting to do for ages.
Picture Style Editor will show you both before and after images while you edit the color LUT. It looks like you can also sample the color from the image. On the right side you can find a list of all edited colors and a luminance editor along with input/outpot text boxes. I wonder how many points could be added to the luminance editor. It looks a bit like the Capture One ICC editor, but never the less, we are very excited here at Click here for full PSE screen shoot.

Update: Canon has a new sub website for the PSE in Japanese.

New Sony APS-C CMOS sensor, 12MP at 10 fps

August 20th, 2007

Sony as today announced a new APS-C CMOS sensor that can read out full 12 megapixels images at 10.39 frames per second. It is doing so by having “line parallel A/D conversion system (column A/D conversion system)”. Are we looking at the next Nikon DSLR sensor? We will know soon… If you recall, a few days before the Nikon D2x was announced sony released a press release describing the new D2x CMOS sensor. More information is available in the press release.

Picture Style Editor 1.0, editing color LUT’s?

August 20th, 2007

Out of the many new Canon announcements today is the new Picture Style Editor 1.0 software. This is very exacting, according the the announcement it will allow us to edit picture style profiles by editing the “style, color, and tone curves”. I hope that by color they actually mean that we could easily edit the color LUT to change how colors are rendered. This would make DDP one of the more powerful Raw software currently available for Canon cameras. Speaking of which, version 3.1 promise to deliver many new lens aberration corrections functions to correct chromatic aberration, color blur, vignetting, and distortion.
