I found this amusing so far. I use the name Apolinario at DPReview. You can call me Raul if you like even if it may not be my real name!
My curves are not the same as the JLMcurve or the e20 curve someone else had posted. I tried out several other curves and most of them did increase low-midtone brightness, however, they did so by sacrificing contrast. What I tried to do is create a curve that created histograms that exactly match the histograms created when you add +0.3 and +0.5 EV corrections in the camera while using the normal default tone setting. With the curves on my website, they do exactly that without any noticeable color shifts. My +0.7 curve, however, does have an increased red and yellow saturation which looks good for some photos(some landscapes), but not others (portraits).
I was working on more custom tone curves for people who wanted less contrast than the normal setting, basically a tone curve that mimicked adding +0.3 and +0.5 EV with the less contrast tone default tone setting. Unfortunately, my USB cable broke! I'm waiting for Christmas to get a new one. Warning: the USB cable does not stand up well against someone taking thousands of test photos while connecting and disconnecting the USB cable in between photos! ;-(
