How sharp are RAW photos before processing?












1















Are RAW images by nature slightly blurry prior to processing? If I open them up in Lightroom and zoom into the photo, my photos are not tack sharp but a bit blurry. Once I process, it comes out looking pretty sharp.



As an amateur I am trying to figure out at what point is the blur a product of user error or if it's natural? I shoot with a Sony A7RII if that makes any difference.

Wait wait wait — let me stop you right there. When you open up RAW files in Lightroom, you are seeing a processed image. Lightroom does not have a RAW data viewer, and the unprocessed RAW data doesn't look very interesting even if it did. What you're seeing is either a JPEG preview (processed by the camera) or the default processing you have configured in Lightroom.



It sounds like the settings for that default rendering include less sharpening than you like. Behind all of this is your fundamental question: is sharpening a necessary part of a RAW workflow (assuming sharp images are desired)? The answer is yes — see Why should my last post-processing step be sharpening?, which is partly about the order but also gives some explanation as to why.



Digital cameras (with the mostly-obscure exception of Foveon) use a pattern of colored filters to create color images. This means color in the final image is produced via algorithms which infer complete color information from neighboring photosites. A final sharpening pass usually makes the results of these algorithms more snappy. And, although it's less common now that higher-resolution sensors make it less necessary, many digital cameras contain an (optical) low-pass filter, which intentionally blurs the image slightly to avoid moire. (See Why is a physical anti-aliasing filter still needed on modern DSLRs?.)



Additionally, digital sharpening (especially the magic that is Richardson–Lucy deconvolution) can compensate for other sharpness factors: missed focus, soft optics, or even motion blur.

    thanks for info! I have always assumed RAW photos have a "default" look. So if I viewed a RAW file on different viewers/editing programs, they would not be identical? If so, then I mean the default processing when using Lightroom CC for iPad. I press the Auto button as a starting point and it seems to get it 70% of the way there to what I would want it to look like.

    Right, that's absolutely the case. There's no default look. This leads some people to say that RAW files aren't even really images. They're... potential pre-images or something. Usually, cameras encode some basic information about camera color settings that can be used by RAW converters, but often that's just ignored, and even when it isn't, each program has its own way of interpreting what that might mean.

There are two questions here:




  • is it normal that the final processed photo is more sharp than what was captured by the lens?


  • is it normal that the RAW sensor readings are more blurry than the image focused by the lens?



And the answer is YES - both the lens and the sensors are not perfect and digital processing is used (and sometimes overused) to make up the imperfections.
