50 mega-pixel photography

(Tuesday, July 8th, 2008)

I don’t intend to go too deep into this kind of extreme photography right now, but I wanted to indicate two news items that could be reflecting on the continuous trend toward larger sensors and additional pixels:

Again, those people are keeping pixel size around 6µm (a good target to keep diffraction low and manageable).

I assume that the lens choice was not the right one. Unfortunately, I could not find the author of this image.

Why go Full Frame?

(Monday, June 23rd, 2008)

With all this talk about existing Full-Frame photo cameras (Canon EOS 5D, Nikon D3) and about possibly upcoming new ones (Sony Alpha 900, Canon EOS 5D Mk II or some other similar name, etc.) many photographers happy with their existing digital equipment are wondering: “What’s all the fuss about?”

And it’s a good question to ask, but the answer goes with some of the comments about sensor resolution. About the same people who noticed that resolution is not all that counts (despite what is said or implied by some of the major brands on this market) also understand that going Full Frame is a possibly very important decision for the attentive digital photographer.

Disable hotlinking

(Friday, May 30th, 2008)

When you have a web site, it becomes quite common that some people feel so easy to just borrow your images that they do not even take the time to make a copy on their own web site. Not only do they use your artwork, but they also use the bandwidth you paid for.

Normally, there is a solution. You can modify slightly your website to ensure that if this happens, the image served is not the original one, but a modified one (either a big red X, or a message to the reader). But it is a little difficult to do by hand. A wbe site tool comes handy for this: HTMLbasix - Htaccess Disable Hotlinking Code Generator.

Soon: A new lens in my bag

(Wednesday, April 30th, 2008)

Happy news here: I finally bought a lens I wanted for quite some time. I found and paid on eBay a Minolta APO G 400mm f/4.5 (Yes! The old white lens that is renowned so much for its optical and mechanical quality, while being nearly impossible to find in auctions).

It will go really well with the Giottos MT 8251 carbon tripod and the MH 1001-652 ball-head I bought a month ago in Shanghai, People’s Republic of China.

Soon to arrive from Osaka, Japan. I can’t wait.

Plenty of tips for food photography

I don’t know why (maybe because I’m looking for them) but I seem to find plenty of posts about optimizing your photography of food. Let’s share some of the best ones here:

PhotoShop Express online - a few reviews

(Sunday, April 27th, 2008)

This was a little event a few days ago: Adobe launched its first beta version of the online PhotoShop under the name of Photoshop Express. As it was easy to predict, it’s not as simple as marketing would like you to believe and you cannot replace one by the other as most of the reviews hereafter will show you:

  • Les Numériques (en français): would better use Picasa to share the images prepared with Photoshop Express, and would want to see Raw files management, curves and histograms, and masks.
  • Ars Technica (in English): it is rahter a cross between iPhoto and Adobe Bridge, but they love the basic features and (including color correction).
  • Baekdal.com (in English) : disappointed; This is not an image editor, by far - just a fun way to apply a few corrections/effects. Woudl rather recommend Splashup, he feels is superior.
  • Photojojo (in English): This is certainly not Photoshop but it does very well what it offers (basic image edition/correction).
  • LifeHacker: Not the Full PS Package, but Good Web-Based Editing
  • Pixinfo.com (in Hungarian): Honest! I didn’t understand what they think about it…

To notice: Photoshop Express is free, limited to 2GB of online storage (easy to reach) and in English only for now.

Upgrade your Canon camera to OpenSource nirvana

(Wednesday, April 9th, 2008)

CHDK screen opyIf you have a simple Point-n-Shoot digital camera, you may not know it, but you are limited more by the marketing teams than by the real technical constraints of your hardware. But if your camera is from Canon you may find an easy way out.

The Canon Hacker’s Development Kit is an open-source software project that can be loaded on cameras using Canon’s DIGIC II or DIGIC III processors. Interestingly, it has the following features:

  • It’s free (as in free beer)
  • Its installation is completely reversible (it does not remove anything, does not replace the existing firmaware, just adds new features installed on-the-fly from an SD card)
  • Faster shutter speed: up to 1/60,000 of a second!
  • Slower shutter speed: down to 65 seconds!
  • Automatic bracketing of exposures
  • RAW file format
  • Live histogram display
  • Battery readout
  • Scripted actions
  • Longer videos
  • More image compression options
  • Use USB for remote control
  • Depth-of-Field calculator

Impressive! The list is long enough to give your food for thought and it applies to an impressive list of compatible cameras.

Nikon manuals

(Wednesday, April 9th, 2008)

I found the user manuals of several Nikon SLR cameras on the web:

2007: 131 million photo cameras

(Sunday, April 6th, 2008)

According to IDC, the sales of photo cameras progressed by 24% in 2007 to 131 million cameras. The global market is in the hands of several companies:

  • Canon: 24.5 millions (18%)
  • Sony: 20.9 millions (16%)
  • Kodak: 12.6 millions (10%)
  • Samsung: 11.7 millions (9%)
  • Nikon: 11.4 mililons (8.4%)
  • Olympus: 11.3 mililons (8.3%)

For the SLR market (Single Lens Reflex), two companies are overwhelming:

  • Canon: 43%
  • Nikon: 40%

Canon looses some ground to Nikon, but the margins were going down thanks to added competition.

Before a tripod: Photo stability solutions

(Monday, March 24th, 2008)

Of course, you know it, a photo tripod is an excellent solution to stabilize your photo camera and get crisp images despite a long shutter time (or a trembling hand). But there are other simple solutions that you should keep in mind:

  • A photo monopod: After all, one leg (instead of three) can be enough, even more if you push the camera against another fix support (a wall, for example). and, the monopods are lighter and cheaper than photo tripods.
  • The bean bag: It’s only a bag filled with dry beans or grain; The result is a deformable and stable base where you can easily push a camera into. Even a heavy one.
  • The self-timer, shutter-delay, remote release function of the camera: Most of the camera moves come from the photographer pressing on the shutter release button. Why not use the self-timer integrated in your camera (even if the supporting base is not very stable, it will improve the situation a lot)?
  • Several images: I use it a lot, shoot three images in a row using the auto-drive of the camera; The first one is most influenced by pressing the shutter release button, but the next ones are better.
  • In-camera shake reduction: Yes, it is included in the camera system just for this purpose. Be it part of the lens (at Nikon, Canon, for example) or of the body (at Sony for example), it brings between 2 and 4 speed stops. But sometimes, you may have to take seevral photos to get one really good (when you are bordering with the limits of the system).
  • Hold your breath: And press the button just after blowing slowly al your lungs air; It’s an old and reliable solution and it works.

Last but not least, do not forget that if the subject itself is moving (and the camera is already stable) there is no other solution than a fast shutter speed (or flash light).
