Olympus mju 725 SW - Test Shots - Full Resolution Crops
A range of test shots are shown over the next few 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.
1/160th, f/3.5, ISO 80
At the minimum setting of 80 ISO the image is relatively noise free, but still looks over processed and has visible compression artefacts.
1/200th, f/3.5, ISO 100
At 1/3rd of a stop faster, 100 ISO produces virtually identical results as the previous image.
1/500th, f/3.5, ISO 200
Already at 200 ISO there is visible colour distortion and image noise, loss of contrast and shadow density, and the image is over exposed.
1/400th, f/4.5, ISO 400
At 400 ISO there is plainly visible image noise and colour distortion, and the image has lost a lot of fine detail. Overall quality is low.
1/500th, f/5.6, ISO 800
At 800 ISO the image quality is seriously degraded, and there is heavy colour speckling and luminance noise right across the image. Even more fine detail is lost, and the image quality is very poor.
1/1000th, f/6.3, ISO 1600
At 1600 ISO the image has lots of coarse-grained image noise right across the frame, which would show up on even a small print.
