Just posted: Compact Camera High ISO modes: Separating the facts from the hype. It's rare these days for a compact camera to be launched without a high sensitivity mode / high ISO capabilities, but the truth behind the marketing hype is often disappointing to say the least. We believe consumers are often being misled by the manufacturers when it comes to the actual performance of most cameras at higher ISO settings and in low light. So we decided to put together a short article for the uninitiated on the truth behind those headline high ISO modes. If you're new to digital cameras or are in the market for a new one this is well worth checking out.
Yes, if you pixel-peep on F31 at high ISO you'd notice that the images are heavily processed to remove noise. For consumers printing at 4R, that's ok, but at ISO 1600, so much colour details are lost that it's hard to do post-processing.
