Toggle between RAW and jpeg with these images. Ever seenanything so weird?

Look at the change in the Canon RAW to Jpeg. Arguably, the best Jpeg and vastly different than the RAW. Pentax is weird too. RAW very good, Jpeg not so good. https://www.dpreview.com/reviews/ima...51288434416907 So tell who is the larger fool, you are the people who posted that? You *can't* look at a RAW image, there is no such thing. The only image you can possibly look at has been converted to an RGB format, such as JPEG. And of course if you see two different JPEG's from the same RAW file it just means someone set up the conversions differently. Whoop de doo! I downloaded the D5500 RAW file shot at ISO 12800. Interesting, as it has several hundred pixels that are clipping in the raw sensor data, in all four colors. The Exif data indicates it is over exposed by +0.2 EV. The embedded JPEG, generated by the camera, from the RAW file has almost 39,000 pixels that are clipping. The "Quality" setting was 76, so somebody intensionally configured the camera to produce a relatively poor quality JPEG. The ACR generated JPEG only has about 10,000 pixels that are clipping. Not perfect, but better than the camera JPEG as far as brightness goes. The Quality setting is 96, which is the reason the file is 32Mb in size; the main point though is the obvious attempt a the highest quality JPEG possible (greater than 92 merely adds size, not quality). Overall, as a test this is simply ridiculous! It means nothing and suckers fools, Rich. -- Floyd L. Davidson http://www.apaflo.com/ Ukpeagvik (Barrow, Alaska) |

Might be more interesting than seeing fanboys ranting about their brand back an forth. There is no "comments section" of that article. -- Floyd L.
