Given your vast output of color imaging as generated from raw data of space missions, good scientific methodology would require a concise documentation of ALL the corrections inherent in ALL your imaging results . Already in case of Mercury I asked you in vain to make the formulas public for the ma...

Here's backlit Titan again, this time with Rayleigh scattering coefficients increased: <cut> There's now a visible bluish-purple fringe. I quite like this version and would probably also increase the depth of the Rayleigh scattering layer, if possible. Is it possible to mix the two effects to get a...

Since the available CICLOPS raw images basically lack physics/hardware-based normalization, neither Matt McIrvin nor Gordan Ugarkovic can really know the truth. Matt carries a PhD in theoretical physics from Harvard. So no surprise that I tend to trust him ;-) . At least he must have had a thorough...

What I have been arguing is that in view of various uncertainties and Ugordan's undisclosed calibration code, it seems to be the safer bet to go for the official NASA coloration . OK, let's play your game. Which of the three different NASA colorations would that be and give me your scientific reaso...

Believing you is not what matters here, if we are to compare two subtly different shades of brown-gray from NASA and your work! For what it's worth, the differences between NASA/APL image 22 and mine that you compared side-by-side pretty much boil down to two things: ⋅ sRGB gamma correcti...

Ugordan, for example, claims that he has written his own code for normalizing the raw images. I wasn't gonna respond to that, but the tone of that statement made me. Yes, that is exactly what I claim because it's a fact. I did write the software based on none other than the following document: http...

So let me ask you then, what community you are addressing with the kind of imaging you are doing? Basically anyone who likes color images of the planets. I'm not targeting scientists nor am I expecting any serious analyses being done on my data. As far as I know, natural color images in this respec...

Since my work is being discussed here, I might as well chime in. Steve, But this was not what I really wanted to know about Ugordan. In his personal profile, http://www.flickr.com/people/ugordan/ he writes about himself: I'm a guy who does programming for a living, have a college degree in computer ...
