Nikon D40 high ISO test

Introduction and ConclusionThe purpose of this test was to see what degredation of the image would be caused by using high ISO settings on the camera. My conclusion is that even the highest ISO settings are useable, and certainly 800ISO can be used as a matter of course, without worrying about degradation of the image. My long-time experience is that plenty of light thrown on the subject also helps – so very low light shots may well still show chroma and luminance noise in deep shadows. Which begs the question of why use high ISO if there is plenty of light about? The answer is that higher ISO enables higher speeds to be used, which is great for moving subjects; and a high ISO sharp shot is always better than a low ISO clean file, but blurred, shot. A note on ISO For those not familiar with the term ‘ISO’, it is a measurement of the camera’s sensor sensitivity to light. The higher the number, the greater the sensitivity. The term is a holdover from …

Adobe Photoshop CS3 – intel Mac version – first impressions

Bridge is much quicker and much, much more stable than in CS2. I hated Bridge in CS2; so much so that if I did not have it open I would sometimes rather go to file/open in Photoshop and trawl through the images in the folders on the computer, than go to Browse and watch the clunky Bridge program open and struggle. All that is changed now with Bridge in CS3. Now it is a pleasure to use and let’s you get right on with finding what you want. After 16 days use it has not crashed on me once. It has however told me on two occasions that it has quit unexpectedly, but on both occasions I had just closed the program. So whatever it said, it had not crashed at all, in fact. I have had that happen with Bridge CS2 also – strange bug. It has a nice Preferences panel to set the background (from black to tones of grey to white) for the images and for the data, and for the highlighted …

Real-World Review of the Nikon D40

Buying considerations and the Competition I got fed up with the weight carrying my D200 around – even with a little 50mm lens – for those not-specifically-about-photography walkabouts. So I read the reviews and pondered the Nikon D40 as well as the Canon EOS400D/Rebel Xti and Xt and small-sensor cameras, such as a Leica D-Lux3, or a Canon SD700, or G7, or A640, or A570IS, or S3-IS and I tried them all save the Leica and the Xt/Xti in a camera shop, and then read some more. I read Ken Rockwell’s review of the D40 and if you are in the market for a small camera you would do well to read it (just Google Ken Rockwell D40). Of course, Ken Rockwell is a firm proponent of shooting JPEGS exposed correctly and using the camera’s settings to maximise the shots the way he wants them. But I shoot RAW and the number of shots I have post-processed that would have suffered had I shot in JPEG, keeps me wanting to shoot RAW if I can. …
