Previously I borrowed a Fuji F200EXR from Duncan Turner of DLT photographic\u00a0<\/a>, the point of which was for me to evaluate the technology that Fuji refers to as EXR.\u00a0 What this technology\u00a0\u00a0essentially\u00a0does is capture two separate exposures at the sensor level at the same time by using half the total photo sights for each exposure.\u00a0 The trade off\u00a0of this\u00a0is a reduced resolution, to half of the total.\u00a0 The benefit is a greater dynamic range.\u00a0 In the case of the F200EXR the resolution drops from 12mpixels to 6\u00a0Mpixels when used in EXR\u00a0dynamic\u00a0range mode.<\/p>\n

This isn’t a lab or a studio test of\u00a0EXR for this camera but as close to a practical real world usage as I could make it.\u00a0 What I found was that the difference was subtle and it was really only necessary to go into EXR mode under harsh lighting, such as a shaded forest with bright sky in the back ground.\u00a0 In EXR\u00a0%400 mode a similar exposure allowed for some retention of highlight detail where in full resolution mode some highlights were clipped.\u00a0 As there is no RAW shooting mode for this camera all images where jpegs.\u00a0 And here is the thing, I don’t think that the EXR results would be superior to a similar camera that allowed RAW shooting.\u00a0 With a slight under exposure bias to preserve highlights followed by some image adjustments during RAW conversion I think that all the stated benefits of EXR could be duplicated.\u00a0 In fact even the high resolution jpegs from the the F200EXR can be adjusted to produce similar results with the right exposure (again a slight under exposure to preserve highlights)<\/p>\n

There are subtle differences between the two modes but is it enough to justify the drop in megapixels?\u00a0 I will answer that “No”.\u00a0 Both modes produce good results with the trade offs mentioned.\u00a0 So what do I think this means in relation to the new Fuji X10 that is being released and soon to be available?\u00a0 I think that the camera will need to stand on it’s other merits such as it’s fast F2.0 lens and it’s optical viewfinder because if you need to look this hard to see a real difference, your time could be better spent taking pictures.\u00a0 I hope I’m prove wrong when the X10 arrives as an advancement in camera technology is worth a bruise to my ego.<\/p>\n
