Casio Exilim EX-Z1000 Compact Digital Camera - Test Shots - Full Res Crops
A range of test shots are shown over the following pages. Here, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it in order for you to gain an appreciation of the overall quality. The following pages consist of resized images so that you can evaluate the overall exposure. For those with a dial-up connection, please be patient while the pages download.
Note: These ISO test shots were taken indoors using diffuse natural light, auto exposure and auto white balance. The 800 ISO shot is taken using Anti Shake DSP mode, and the 3200 ISO shot is done using High Speed Mode. These ISO settings are not available in other modes. The camera was mounted on a tripod, and the 2-sec self timer was used.
¼ sec, F3.8, ISO 50
At the lowest ISO setting the image is crystal clear and sharp as a metaphor. However the auto ISO system will hardly ever select this setting except in really bright weather. Best to use manual.
1/10 sec, F3.8, ISO 100
At 100 ISO the image is still sharp, smooth and noise free, just as it should be.
1/20 sec, F3.8, ISO 200
At 200 ISO there is a hint of noise in some mid-tone areas, but it hasn’t affected the lighter or darker areas.
1/40 sec, F3.8, ISO 400
At 400 ISO, the highest normally available setting, there is some image noise visible in the darker areas, but it is very fine and unobtrusive.
1/80 sec, F3.8, ISO 800
In Anti-shake mode the camera selects 800 ISO to ensure a fast shutter speed in low light conditions. It reduces shake, but there is a lot of image noise and the picture quality is seriously degraded.
1/320 sec, F3.8, ISO 3200
In High Speed mode, the ISO setting is pushed up to 3200, but the noise reduction system has removed a lot of fine detail and added a lot of artefacts. Not a good picture.
