07.08.10DxO and their completely ridiculous licensingI'm using Previously I used DxO Optics pro to adjust and correct some of my images. But because of their stupid licensing system I've been forced to use other solutions lately. And my conclusion is that you probably don't need DxO. The licensing I'm using several professional software packages. Adobe Lightroom, Photoshop, Final Cut Pro, iStopMotion Pro. Elgato Turbo HD, Apple Keynote etc. Pretty expensive and professional software. I'm working on several different computers. But my main workstations are: 1. My MacBook Pro (on the road) 2. My 24" iMac (at home) 3. My MacMini (for time consuming batch jobs) I would guess that laptop + desktop machine ...

06.10.10Quick test of some flashlightsI needed some flashlights for use in water this summer and gave dealextreme a chance. After some reading I ended up with an UltraFire W200 and a Diving Cree SSC-P7. My conclusion so far is like most people that have done some flashlight research. The way the vendors measure Lumen must be completely different from each other. The 175 Lumen UltraFire is extremely bright and much brighter than my existing 100 Lumen LED Lenser T5. And the Diving Cree SSC-P7 that is supposed to be 900 Lumen is by far the brightest, but not at all 900 Lumen if they measure ...

06.14.09Test images from my current camerasAs 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 ...

05.04.09DXO 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. My original image Corrected with DXO Optics pro Corrected with DXO Optics Pro with new aspect All sorts ...

04.04.09Aperture and the huge differenceFirst 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 50 mm @ f1.4 Yes. That's the same lens, the same camera and the same conditions. ...
