Test images from my current cameras

My available cameras today (shot with my 5D2, so it's not in the image)

As part of some experiments I’m running I snapped more or less the same image with all the cameras available to me today. The devices you see in the image above in addition to my 5D Mark II (that I used to snap that image…). Simply because I wanted to be able to compare some details.

And my conclusion? Once you go full frame you never go back. If I’m shooting anything even remotely serious I’ll bring my 5D2. Now if someone could give me a full frame digital compact with the size and weight of my old analog (and indeed full frame) Olympus XA

DXO Optics Pro Rocks!

I have written about how to correct Fisheye images in this blog before. Now the team behind DXO Optics Pro have built support for the combination of Canon 5D MarkII and my Canon 15 mm f2.8 Fisheye.

And look no further. The best fisheye correction you can get is here. DXO analyze the different lenses in detail. On the specified camera. So you need to check if they have a module for your lens / camera combination. But if they have, DXO does the best corrections possible.

All sorts of corrections

I’ve just scratched the surface of this program. It does all kinds of advanced corrections. Here is my old test image from the 50mm f1.4.

Original 100% crop at f1.4

Any chance that DXO can do something with this total mess of optic errors?

Pretty impressive! But before you run out buying crappy lenses thinking that you can save everything in DXO, have a look at the same image snapped at f5.6:

Proper optics out there in the field is the best way to go. But so far I’m impressed with DXO. It’s worth the fisheye correction on my 15mm alone!

Aperture and the huge difference

First of all: The Digital Picture.com has an excellent page where you can compare the sharpness of different lenses and different apertures.

But recently I did some quick tests with my 50 mm f1.4 myself. It’s a decent lens and regarded excellent for the price range. And it’s pretty fast, featuring an aperture of 1.4. But lenses loose sharpness and contrast at low apertures, and I wanted to know exactly how much. In this lens the difference is huge. Here are two 100% crops:

50 mm @ f5.6

50mm_at_56_100crop

50 mm @ f1.4

50mm_at_14_100crop

Yes. That’s the same lens, the same camera and the same conditions. Only a different aperture value. But will you see the difference if you snap an image at full resolution and reduce the size down to what you’ll need on a web page? Let’s have a look. 21 megapixels from my Canon 5D MarkII reduced down to an image that is 500 pixels wide.

50 mm @ f5.6

50 mm @ f1.4

img_6182

And I guess you’ll need a slightly trained eye to see the difference clearly. First of all you see the vignetting: darker corners. Then you see that the DOF is more shallow and that the cars at the bottom of the image in the f1.4-version is not completely focused. This is how it should be. A shallow depth of field is one of the beauties of a low aperture value.

But if you look closely you’ll see that the overall sharpness and sense of depth in general in the f5.6-image is better. Even when the image is reduced down to this size.

So, if you want the ultimate in technical quality you should plan your aperture. And buy very nice lenses…

How to remove distortion on a Fisheye image

IMG_1284

I recently bought the Canon 15mm f2.8 Fisheye for my new 5D Mark II. It’s extremely wide angle and gives the characteristic fisheye distortion.

Here’s a gallery of images shot with that lens:
http://www.flickr.com/apps/slideshow/show.swf?v=63961

In some images you want the fisheye distortion, but in other images you might want to remove it.

And there are several applications that can help you with that. Regardless of what fisheye you’re using.

ptlens

The most common way to remove the distortion is to squeeze the image in the middle. Something like what PTlens will do for you. In addition you can adjust perspective, rotation and a couple of other settings.

But this leaves you with an image that has to be cropped and if there are people along the edges of the image they will look very distorted.

Another program called Fisheye Hemi aim to fix that problem. And will try to remove the fisheye distortion using advanced algorithms to keep as much as possible and do the adjustments but keeping people and other details in the image without distortion.

I’ve made a simple flash animation to show the different images. Click the buttons below the image to change from original, to the one corrected with fisheye hemi to the one corrected with PTlens.

There are a lot of programs that is made to help you adjust lens distortions. I’ve also tried DxO, but simply found it too difficult to use. For people using Windows I’ve heard positive remarks of RectFish.

Different seasons in one image

If you have been following this blog for a long time you know that I did an experiment snapping images out of my window for a year. I made a video that was hugely popular and my images have been used in several interesting projects.

At that point I snapped the images with a Sony compact camera. After buying a digital SLR I decided to do the same thing. But this time in better quality and not shooting the images through my window.

I still have a couple of months before the next year of images are captured, but I have enough to do some experiments. Mainly because I want some feedback. This time I’m shooting three exposures each time. Giving me the possibility of putting them together using HDR software.

The following video is a horrible rough cut of the images so far. The black levels are completely off, the HDR effect too strong and the video is way too long for this kind of viewing.

The audio is actual audio captured at the same spot that the images are taken, but not at all synced with the images.

Still, it would be valuable to get some feedback and ideas. That will make it easier for me to make the final video perfect when I have all the images at some point late this summer.

Never bored – Part 2

I wasn’t bored at the Zurich airport, and as you already know I found some entertainment in Frankfurt as well. In addition to the band and the CEO of the whole airport I just had to shoot the tunnel between terminals A and B.

A fantastic place for a 10mm super wide angle. I traveled alone, so to put a person in the image I had to use myself. And when leaving the camera on the floor, walking down the hall to let the timer shoot an image some of the other people in the tunnel started looking pretty suspicious.

But I managed to shoot a couple of nice images without being bothered by security. And apparently I am not the only one finding this spot interesting.

Romantic images sell

I post the image above to one of my galleries on SmugMug. Then I get this comment:

Hey, redo the picture and you’ll have a heart shaped sky! Do you see it? If you would crop out upper half of the picture and turn it 180 degrees, you would have a heart. and you know…. romantic images sell!

And seconds later I’ve done some cropping and rotation in Aperture and this one is up there as well.

Haven’t sold it yet, but I can see all kinds of embarrassing metaphors popping up. “Look up and you’ll find love”. Blah. Blah. I’ll let you know if someone buys it.

The interesting thing here is how the community steps in and gives valuable advice. Just because they can.

Romantic images sell

They stole an image of my son and just had to pay $4000

Edit:
I seems like I’ve done a bad job selecting words for my headline. Some people think that I am complaining because I “just” got $4000. I’m not complaining. It’s a not-so-successful formulation to say that this happened recently. Or like one of the commenters over at Reddit said:

“I assume that “just” refers to time. Meaning they only now, a short while ago, had to pay $4000.”

About a year ago I was surprised when I saw an image of my son in an ad for a shop called “Vinderen Elektriske”, selling electronics.

I immediately contacted the editor of the magazine in question, “Vinderen Magasinet”. She directed me to the advertiser and the designer behind the ad. I contacted the designer. She had found the image “on the internet” and reacted like I was rude and angry without any reason when I told her that she couldn’t use the image without my permission. I was obviously talking to a professional designer with absolutely no knowledge of intellectual property laws.

The use of my image is a very clear violation of several paragraphs in those laws. Both because I own the rights to the image and because they need permission from the easily recognizable person in the image.

So I called the manager of the shop responsible for the ad. He was not very friendly either and simply directed me to their lawyer. Probably in hope of me simply forgetting about it because I didn’t want to fight their lawyer.

Unfortunately for them this simply pissed me off. Seriously. I am not too difficult when it comes to people wanting to use my images. An apology and a suggestion for some kind of compensation would have been okay. But now I just went from a minor irritation to pure anger.

Fortunately I am pretty well connected and a couple of emails later I am in contact with the utterly talented Mr. Halvor Manshaus. You know, Jon Lech Johansen aka DVD-Jon’s lawyer. A lawyer you don’t want on your neck when discussing digital rights.

But he’s not cheap. Not even after a couple of beer and a very interesting discussion about technology and new media… And with this incident I don’t know if I’ll get any kind of economic compensation in the end, so I have to put aside thousands of dollars and prepare to cover the expenses if I lose.

Most people would probably just give up. That’s why this story is important.

Some weeks later I am fortunate enough to meet Mr. Jon Bing at a conference where we both where speaking. Jon Bing is a Norwegian writer and law professor at the Norwegian Research Center for Computers and Law. I tell him about the case. He tells me that the economic compensations people get in cases like these very often are pretty low. But he also says that the case is somewhat important and that I should go through with it to state an example. I should do my duty.

Okay. This would cost me time and money, but I’m pissed, the professor tells me I should do it and Halvor Manshaus is at my service.

I instruct Mr. Manshaus to go on and send a proposal to the lawyer that Vinderen Elektriske was using. He proposes a compensation of about $8000 and make it clear that they have violated Norwegian law of intellectual property. He also asks for documentation on exactly where they used the image.

After a while they reply that this is out of proportions and that they won’t pay more than something like $1000,- No apology and no documentation on the usage.

I don’t accept this. Mr. Manshaus sends another letter. This time with even more references to Norwegian law and a statement about the fact that I am willing to go on and charge them for violation of intellectual property law.

They fail to answer on time and we need to send a reminder with yet another letter. In the next letter they propose something close to $4000,- as long as I prove that it’s my son in the image(!) That’s not very difficult to prove. Because I don’t have the time and money to push this further I accept the $4000,- It’s enough to cover my expenses and leave some dollars that I will put away for my son.

Still, Vinderen Elektriske never gave me proper documentation on where they used the image. They never gave me any form of apology.

But at least it states an example. And I hope the designer now have learned that she can’t just use whatever she finds through Google Images and I hope Vinderen Elektriske are more careful the next time they put together an ad.

And there is another important lesson to be learned here. The one about communication and marketing. In about 20 seconds the owner of Vinderen Elektriske could have avoided:
– $4000,- in compensation to me
– Expenses for his own lawyer
– Bad publicity

How? Instead of answering

“We found the image on the internet. Talk to our lawyer”

He could have said something like

“Oh. I’m so sorry. Our designer must have made a mistake. We really liked your image. How can we fix this? Of course you should have some kind of compensation. Maybe you would give our shop a visit and pick a Nintendo Wii and some games for your son?”

Unfortunately they selected the other option. Pissing me off. Making sure I now hate really dislike Vinderen Elektriske. Making sure my family, most of my readers and huge amounts of people around the different forums where this story has been shared also hate dislike them.

Fools.

What I’ve been up to

Straw
Vacation. Yes, in Norway most of us can enjoy about five weeks of vacation each year. Spending some of it during winter, but usually most during summer.

Tent
This time I’ve had fun in the mountains.

And what’s up on eirikso.com? I am working on a lot of details with my new design and my new host. But I also have a lot of interesting articles in my list of drafts. I am geeky enough to include some technology in my vacation. You can expect an article about navigation systems and how they’re excellent entertainment for your geeky kid.

Navigation
And as some of you might have noticed already. An article about my recent experiments with HDR photography.

And of course a lot more. I’m not spending hours on redesign and a a new host because this blog will be less interesting in the coming months!
