A Quick Look at One M9 RAW Photos

yesterday, htc updated their htc digital camera application for devices with htc feel. usually, this is not worth discussing, however the changelog had an entry for raw images mode on the one m9.

for the ones which can be unusual with what a raw image is, in essence it is exactly what could come to thoughts in relation to something this is "uncooked". the record efficaciously encodes the sensor's records at every pixel, without any loss or tremendous processing. typically, this file is absolutely hidden from the user, and as soon as it enters the picture sign processor (isp) it is most effective used to supply the final jpeg and is possibly deleted as soon as the jpeg report is stored to inner garage. as a end result, we grow to be with a file that may be without problems examine by using any pc, but is effectively not possible to change in a meaningful manner. a uncooked/digital poor may be without difficulty changed to look nearly nothing just like the authentic image, but is impossible for maximum applications to view properly.

fundamentally, a uncooked photo is an unprocessed picture, and if you can see the uncooked image with out demosaicing to handle the digicam's pixel layout, it'd appearance nearly not anything just like the very last picture. however, it's this fairly unprocessed country that lets in for potential profits in image nice. in any case, the isp ought to determine a way to procedure an photo without human intervention in an powerful manner, and it also need to procedure and save the image within approximately a third of a 2d or less. relatively speakme, if i method it myself i'd spend a stable 5-10 minutes playing with sliders to get an amazing balance between noise, detail, assessment, and dynamic range, and each picture calls for a 2nd or two of most cpu load on a present day center i7 4702hq.

the real query is whether raw photographs could make a difference in a digicam's output. in my enjoy this does rely pretty a bit. something like the nexus 5 did not in reality see any extra benefit from hand-processed snap shots. but, the one m9's raw photograph mode well-knownshows a pretty beautiful difference in image great while properly processed. so as to reveal it off, i took some short evaluation pictures. our first comparison is a sunlight hours shot, that is only immediately comparable between the m9's jpeg and raw output.

jpeg m9


raw m9

we will start with a totally simple daylight evaluation. please observe that for this shot it is best comparable among the m9 raw and jpeg output, as the iphone 6 shot is from the identical region, however at a one-of-a-kind time of day and a couple of weeks apart. in the authentic assessment, i referred to that the only m9 regarded to have detail equal to the iphone 6 with its 8mp digicam in sunlight hours. this single test shows the huge upgrades that can be determined with a few short publish-processing in lightroom, with unique emphasis on the advanced shadow detail within the backside left side of the image, the dramatically advanced detail at the building to the top left of the image, and stepped forward element on quite lots any tree in this image. there's a sizeable grain to the photograph that isn't always as suggested at the isp-processed jpeg, however the noise is surely masked via blurring rather than truly getting canceled out. once more, it's crucial to note that the iphone 6 picture isn't pretty at the same angle or from the same time as the one m9, but it have to serve as a great reference for gadgets inside the scene.

the real check is in low mild, and for this i delivered some additional phones and a tripod to try to get a take a look at that became higher-controlled, even though this is not a managed check in the strictest sense to start with.
