These are 100 percent crops of photos of our test scene at each of the camera's available ISO settings. For the WB250F features come before photo quality. I'm not saying the photos are bad, just that if you're shopping by megapixels, you probably won't like the results when viewed at full size, limiting how much you'll be able to enlarge and crop. However, if you're main concerns are getting better photos than a smartphone and a megazoom lens in a smallish body at a good price, then you're set with the WB250F.
Like many point-and-shoots with its price and features, the WB250F does well up to ISO 400, so you'll be able to get good-looking shots when you have plenty of light. Photos get noticeably softer from noise reduction at sensitivities above ISO 400; going above ISO 800 isn't recommended as you lose too much detail and colors desaturate. That said, the built-in flash is actually useful since it can be angled up and bounced, getting you better results than you'd have without flash or with a blast of direct light that you'd get from other camera flashes.
Pop-up flashes aren't uncommon on compact cameras, but few can be tilted back allowing you to bounce the light off ceilings and walls. The WB250F's flash can do just that and can make a big difference in your results. These three shots were taken in Auto mode. Without the flash (top) the camera uses ISO 800. Using the flash and leaving it pointed forward (middle), the camera uses ISO 100, but you end up with a typical crappy point-and-shoot flash photo. (It's better to use this position for backlit subjects.) Pulling the flash back and bouncing off the ceiling (bottom), the camera only goes up to ISO 240 and makes a difference in overall quality.
