A uniformly lit portion of the sky is what is pretty good flat field to check sensor uniformity. Rotating the camera allows to differentiate between sensor and sky non-uniformity. De-focusing the...

If you are interested, here is the compression curve http://cl.ly/1b13163l4531/SONY_NEX5N_Curve.csv

One more request if you do not mind. Can you please check that shutter speeds 1/60, 1/125, 1/250, 1/500 result in linear brightness progress (black level being set to manual 32 for all channels) ?

One thing I would ask you to check is the sensor uniformity. Couple of shots of uniform sky rotating the camera 180 degrees on a tripod so that the same portion of the sky is projecting onto...

I set the Preferences for analyzing unmodified raw data. Yes, but the result is the same - the histogram peaks move in ISO setting progression.

If you look at the Preference pane in RawDigger you can see I switched decompression and multiplication off. RawDigger also allows to dump the decompression curve in human-readable format.

Thank you. Here is what I see:

Right, of course. I think free EXIFTool does a lot of metadata decryption.

Apart from this, and from what The_Suede wrote below, focusing accuracy, camera shake, lens resolution, aberrations, and the camera elements alignment affect perceived DoF too. The tests for DoF...

If exposure the maximum possible exposure is used the image is as low noise as it can be? But I still do do use a handheld meter to know how much I'm underexposing for the midtone-to-be. The...

Looks so. http://www.dpreview.com/forums/post/52270702 http://www.libraw.org/http://www.rawdigger.com/

Please wait till beginning of the next week for the public beta with Foveon support.

My dear friend, I do not have this camera right now. If your bandwidth allows, please, upload the test raw files.

That's why I suggested to work from his samples.

We do not know yet what happens with NEX-5N - it might be that the light was changing between the shots to compensate for the ISO increase, as I used Imaging Resource samples. Please have a look at...

All the conversion settings are the same except for the white balance that is sampled in the marked area on the Neutral 8 patch of CC24. Indicated Lab readings below the histogram and to the left...

Now I know what is an image to you :) And another. http://www.libraw.org/http://www.rawdigger.com/

Both do. Overall, the pushed one is better before befouled. Another bogus one. http://www.libraw.org/http://www.rawdigger.com/
