Coherent Ramblings

Coherent Ramblings

A strange name and almost an oxymoron, unless you understand.

Take the photo of some of my friends herding cattle above - to the untrained eye there would be many cattle and calves rambling along going seemingly wherever they wanted, yet while moving these cattle great distances they all end at the intended location.

Such is life and these web pages, an un seemingly ramble, yet coherent.

These pages are not updated regularly or often, but I post things I want to affect or make a point about. I maintain pages that receive over 1,000 unique viewers per year.

I do not want to get into age, but I have decades of life experience (that woul dnot be two or three!). I've raced cars, climbed mountains, can easily survive in the desert or the mountains, sailed the seven seas and some more, and owed several businesses all of which have been sold for a profit.

Occupations have included a dog trainer (racing greyhounds), machinist, professional photographer, a pattern maker (ask if you must), information architect, a Sailor, human resource specialist, web designer / developer, graphic designer, marketing communications specialist, and work in information technology.

Here are a few links to older work that some seem to still seek out -

Why no CorelDraw X6

I simply did not see enough of a compelling reason to upgrade. If I used the program full time no doubt I would have upgraded.

For the most part rgw CorelDraw X5 Fist Looks is still relevant. Just google for what is new - it is a short list.

If you own a CorelDraw version before X4 you are no longer eligible for an upgrade price!

 

 

36 Megapixels - Really!

Many awaited the replacement of the highly rated Nikon D700 for quite some time - only to rewarded with the D800/E with 36MP images!

Rewarded? Many moans and groans could be read on the internet about 36MP, people had not expected such a high resolution camera! Others ooh'd and awed over the possibilities while others took a "wait and see" attitude.

At the announcement of the Nikon D800/800E Nikon set out to prove the camera to be a truly world class camera by introducing some of the "best photos and video" ever used for the launching of a camera. Nikon also issued a Technical Guide to explain how to get the best out of the camera, which many interpreted in all the wrong ways.

You have to use a tripod, can only shoot in live view, use only the best lenses, can't shoot above F8 without compromising the image quality due to diffraction, and the camera could not be used for sports because it only shoots at four frames per second, are often mentioned on the internet.

Those people missed the technical guide's main point of "to get the best possible images" from the D800/E a photographer would need to use the best equipment and shooting techniques. Geesh, that is the same advice to get the best results for any image as far back in photography history as you can go!

Since most people do not photograph to get the best possible images from their cameras, that left a lot of territory for hand holding, consumer lenses, and sometimes even less than ideal photography techniques.

Photographers have since demonstrated all those beliefs are incorrect and the camera can produce outstanding images while handheld, not using live view, using consumer orientated or older lenses, can use apertures above f/8 and still get outstanding images, and even sports photographers are using the D800!

The D800 seems to pull the best image possible out of almost every lens that has been on the camera. There are a few lenses that the D800 seems to highlight the flaws of the lens, but you will have to do a lot of research to find out about these and even more to validate the claim, and then see if the claim is relevant to you or not.

But 36MP is a Burden and Too Big

Often heard or read on the internet is  - 36MP is going to eat through hard disk space and I'll need to upgrade my computer to process the images.

Those may very will be true! Especially if you are the type of photographer that sprays and prays approach to get an image.

What I'm talking about are those that take many photographs with little thought as too what they are capturing. At a recent air show I was picking my shots and occasionally using my cameras capability to shoot two or three quick frames at 5 frames per second, to increase my likelihood of a spot on focus image. Next to me was a photographer taking photos of every plane pass and shooting at eight-ten frames per second for every pass. (Which made me think my camera was malfunctioning and taking only 1 image per second  when I wanted a couple of high speed burst!).

I ended up with 600 photos for the day, the other guy had over 8,000! How do you even sort though that many photos to find your best amongst all of the less than desirables! And if had been shooting with a D800 at 4fps for all of those images! Talk about gigabytes …

Here are some options -

Take your time to compose and photograph only what looks interesting. If there is not a shot there - don't take it!

You do not have to shoot eight-ten frames per second to catch the image you want. In everything there is the height or highlight of the moment. Know your subject, understand the action taking place, learn to anticipate the moment you want, practice eye hand coordination timed with your camera capabilities. Click the shutter at the moment!

Become scrupulous about the images you want to keep and delete the others!

Do not shoot raw if it does not fit your purpose. Raw photos need to be developed to produce the final image. You camera will change your images into jpg files which are much smaller in digital size. But if you want the latitude of raw files there are other options.

Some cameras allow you to change the file and resolution of the captured images. Some Canon cameras allows one to select the recorded size of raw images. Nikon has other options.

Some Nikons produce 14 bit images which are digitally larger than 12 bit. You can change to saving 12 bit images reducing the file size. Nikon also offers several levels of compression from none, to lossless compression to lossy compression.

These can be combined, or not, with cropping options in the D800.

The D800 allows you to select several cropping options that change the size of the captured raw image. The D3 series and D4 cameras offer several of these options as well while the D700 only offers the DX crop.

You can further reduce the file size by choosing one of the options below. Note that Nikon states that even changing to 12bit and lossy compression you will not lose any visual quality and is similar to saving an image in jpg format without compression.

So 36 Megapixels Really?

Yes! There seems to be several emerging types of users for 36 Megapixels.

Which brings up the questions -

Is the D700O the equal of a D800 image
shot in DX crop mode?

Most are stating that yes that is the case. I have relatively a small comparison base but for me the D800 does produce slightly cleaner images from the DX crop mode than the D7000 at full resolution. The difference is slight, but notable, and was the straw that was enough enough to push my choice to purchase the D800.

The Worst of the D800

Rumors!

See the first section of this article. Almost all have been demonstrated to be just that, unfounded rumors!

Some D800s have a left focus point deficiency, but some would have you believe that the camera should be recalled. Yes there are some D800 that have a left side focusing issue and Nikon will calibrate or repair your camera if needed.

My D800 lacks the clarity of the middle sensors for the extreme left focus points but at this time I believe mine to be in within an acceptable tolerance range. I have only tested it with a 17-35mm lens and need to do more testing, but the images the camera produces are truly phenomenal!  So I do not have  major concern. Nor have most users even stated such a minor issue if it even exist for them.

If you have a D800/E an have not made a 30 inch print - you need to do so! Why is this listed on the worst of the D800 - because web images and smaller prints cannot replicate the awesome resolution and image quality of a D800/E! You will not understand until you have compared a large print with what you see on your computer!

The price - yes for some, but you expect too much if you think the D800/W should be priced lower.

36MP - Well that was primary point of this article. The 36MP is so amazing that the 36MP can actually mask the problems of many less than ideal photos!
