Even if you force the HDR mode ON, it only produces regular, single exposure photos when holding the shutter button. The reviewer probably just looked at the HDR switch and assumed it also works in burst mode without actually checking the result. So, your ...


If I take a photo with my iPhone 5s, the photo is a JPEG and approximately 700 - 2,000kb. If I take a snapshot of that photo on the iPhone, the resulting image is a PNG and approximately 200 - 300kb. (To take a snapshot I would view the photo, full screen, then press the Home and Power buttons simultaneously). You can also install an EXIF viewer app - ...


Take a newspaper, and shoot it from a normal reading distance, starting from an exposure that results in only traces of the letters over paper rendered bright white and all the way down to the paper rendered black. Bring the shots to computer, open them so that the scale is 1:1 and see the range of exposures where you can read the articles, including small ...


You can do what DxO and others do - make test photos and analyze the result. Dynamic Range can be measured using the test chart displaying a range of fields of known brightness. imatest is one of applications that automate the process (see: but this is all maths and image processing and could be performed "by hand" by a ...


I think the simple answer here is "you can't". "Dynamic range" isn't a concept with a simple definition, so unless you can get numbers from DxOMark as you've quoted for the NEX-5R and RX100, then you can't compare them. As an example of this, compare DPReview's test of the Sony a6000 where their tests give a dynamic range of 8 2/3 EV for the A6000 (the green ...
