CCD and CMOS – The Leica Debate

NEC-2

For the big names, they can never win.  Just look at the things Apple get critiqued for.

I have two CCD cameras, a Leica and a CCD PhaseOne back for my Hasselblad.  I like the muted subtle look of the colours.  The sharpness of the image and the more film like dynamic range.  Out of camera the images can look more pleasing, plus the noise is far more organic.

CMOS though is winning as a technology and has many advantages, not least the high ISO performance, high dynamic range allowing you to post process the images in more directions.

I have heard many people say they will refuse to upgrade to the latest Leica rangefinder because its CMOS, so was very interested to find the article I have linked to about comparing a Leica M9 (CCD) and a Leica M (240-CMOS).

I think the article finally puts to rest the CCD/CMOS is better then CMOS/CCD and that the firmware and post processing is more important.

One of the big complaints about the latest Leica and its something true about Leica in general is that when it first came out the white balance was poor and skin tones and red was not right.  After the camera had been out about a year in the field Leica finally got it right with a new firmware release.  Its something that is quite common for Leica.  I think it was this colour issue that put more people off the new camera then its new CMOS sensor.

Lightroom – working from external drives

ev SSDWith Lightroom, I have the application on my internal SSD, the database on the internal SSD and the Cache on the internal SSD.  The photographs I am currently working on the internal SSD whilst completed images are on external hard drives.

Now that I am looking a getting a new computer, one of the options is to use my old laptop for occasional light use, my wife’s laptop for heavy use when I need power and portability; and the new computer for maximum power and colour critical work together with the Adobe RGB monitor.

This will entail moving between Lightroom databases, possibly having a master Lightroom database on the main computer and a working database that gets moved between the other machines.

While Lightroom works well with importing and exporting databases into other databases, one of the options I have been testing recently is putting the working database and photographs onto an external drive, possibly an external SSD.

It seems that the key to getting performance out of Lightroom is raw processor power.  As long as the application is on the internal SSD, and the Lightroom Cache is on the internal SSD then the database and photographs work quite happily on a external drive, either FireWire 800, ThunderBolt or USB3 (USB2 not quite so well).

Lightroom Preferences

The camera RAW cache settings depending on Lightroom version is between 1 and 5 GB.  This is far to small.  For a laptop 20 GB was recommended, and 100 GB for a desktop, since Lightroom V4 Adobe have changed the cache format so 20 GB may be enough for both laptop and desktop use, unless your catalogue is particularly large.  If you use DNG or convert to DNG, then its also important you have fast load ticked.

For now, I am going to create a new Lightroom database on a LaCie external drive that is both FireWire 800 and USB3 and keep switching between my laptop and my wife’s laptop and see how I get on.  If its works well I may invest in a G Tech ev drive and dock.  The dock can be left connected to the desktop I buy.

Fuji X100T and my first real tryout

Fuji X100sA few weeks ago I finally got my hand on a Fuji X100T, at first I was less then impressed until I realised that the battery was very low and Fuji’s when low on power and/or have the power save features selected do limit some features.

On Tuesday this week I had another play, thanks to the local Lincoln London Camera Exchange.  This time I was much more impressed, after setting the power mode correctly and ensuring that there was a fully charged battery I managed to give it a good test.

I liked the way the optical viewfinder works and the speed of performance is now more then fast enough.

I am still torn in the direction I should take with my compact.  I might just in the end buy a better small bag for my Leica and use it with a 24mm, 28mm, or 35mm lens.  If not that then its something like the Leica X, Ricoh GR, or Fuji X100.

Still in usability the the Fuji is a great little of camera, the only concern I have is with the X-Trans sensor, and the option that if I want a compact, then go completely left of field and buy a Olympus OM-10, which is as small as most good quality compacts.

Spring and the evening light

All Saints ChurchNow that the spring is finally here and the clocks have changed to British Summer Time, there is no excuse for not going for a walk on these lighter evenings and taking a camera with you.

While not a fantastic picture, I like this because it reminds me of the warmer evenings to come, with the blue sky and late evening sun kissing the church’s tower.

I’ll be going for a lot more walks now and if the weather is anything like the last few days, definitely taking a camera and shooting a few shots.

 

Veg Plot update – planting the potatoes

garden-3

 

Until this Easter weekend the veg plot was looking a little bare.  While we have seeds planted out in the cold frame, the only thing in the veg plot is last years leaks and this years onions.

This weekend we set to and planted the potatoes.  Its going to be great harvesting some fresh new potatoes and some salad leaves in the early summer for lunch.

Graphic Cards and Monitors

I have been researching what I want from my next computer and I have been considering recently image quality.

The computer is our view into our photography. But what is the limitations of editing high high quality images. The computer or the monitor?

Looking at the software I use, it is recommended that the memory of the graphic’s card is at least 512 MB. Modern inbuilt Intel graphics and discrete graphics all have at least this.

The other limitation is down to the lookup tables built into the hardware. Laptops generally have 8 bit screens, but external high end monitors have 10 bit hardware, meaning higher quality images and better editing without the possibility of banding becoming an issue.

This means that for general work a basic laptop will do the job, but for detailed colour work you will need to plug it into a high end monitor; for more intensive work then a machine with at least 8 GB of RAM and 512 MB of video RAM, 12 GB of RAM plus 512 MB of video RAM for photoshop.

So for general work a MacBook Air with 8 GB will do the job but for more extreme work at Mac Mini with 16 Gb, or a MacBook Pro or Mac Pro/iMac is required.

The top picture is from a Leica X Vario, the second bottom picture from a Leica M (240. The top camera was generally hammered and dismissed on the internet. The middle picture is from the Leica X a well rated if expensive compact.

I have been showing these pictures round to see what people prefer. In theory the most modern camera should win but in fact is was the oldest. Which possibly shows that something else is more important then how modern the camera is.

It can truly be said that we have never had it so good. The most modern cameras may make life easier and pictures easier to take but when it comes to image quality the improvements are now very small. Its more important to choose a camera that suites you and the sort of pictures you take, and most important of all, one you enjoy using.
