Been shooting steam too long, forgot about ditch lights...  :D I guess my budget has saved me; with the cheap lenses I use, haven't seen any of that.  Well, I haven't taken the AF-P 70-300 on an ...

Just read Thom's paragraph on that, and he advises, "but do be aware of near edge light sources.".  Y'might squirt him an email directly, ask about the correlation of ghosting to the placement in ...

I'm 3D printing HO scale model steam locomotive parts, the details are so small I can't really see them well even with magnifiers. So, I use my Z 6 and AF-S Micro Nikkor 40mm DX lens to take ...

It's good your personal failure experience is non-existent.  So is mine, 3 drives running constantly in two machines.  But those are way-too-small samples to inform the general case. Ask anyone who ...

I've both worked with and taught distributed computing systems, and I've found data backup to be the most mis-understood yet critical thing to manage.  Someone else mentioned understanding your ...

I have two levels: 1) a second machine to which I incrementally back up at each new photo session; 2) multiple portable USB hard drives that I re-do from scratch every couple of months from the ...

I don't do birds, but I use this metering mode all the time with my Z 6. What you need to be prepared to do is to spend time in post lifting shadows. It definitely protects highlights, but at the ...

I started out shooting JPEGs and damaging them in Picasa. Long story short, I wanted a better outcome and it led me to this. Now, I'm a programmer by trade so writing programs isn't daunting, but ...

Cool beans!  We do something like this at discuss.pixls.us, called "PlayRaw".  I've learned a lot from doing it, considering others' approaches. I did this render of  your .CR3 in rawproc, my hack ...

I have spent the last couple of years chasing what it takes to make decent color in my photographs, and I've essentially found that I need three things: 1) a decent camera profile, 2) a good ...

Is this the lens: "Lumix G Vario 100-300mm f/4.0-5.6 Mega OIS"? If so, it's in the current lensfun databases.  Also, the camera shows up, as the "DC-G9" per it's nomenclature from the metadata.

Without getting into a race discussion, here's a comparison reference you can actually look at either on the device itself or various renders on the internets. For reasons that escape me, I ...

Yes. I was curious to see how the dcamprof methodology would compare, although I see it'd be a more appropriate comparison with the natural colors spectra...

Jim, I finally got to the basement and made some dcamprof ssf-to-matrix profiles.  I have the camspec database; from there I picked the Nikon D50 for comparision, as I actually have that camera.  ...

The fellow who wrote the software I use to make camera profiles, Anders Torger, had this to say about matrix profiles: http://rawtherapee.com/mirror/dcamprof/camera-profiling.html#matrix_profile I ...

A well-constructed matrix and relative_colorimetric intent seems to do well for the majority of images, where extreme colors don't dominate.  I started down the LUT/SSF rabbit hole when I shot ...

Yes, I think what I'd be doing is validating dcamprof algorithms... After dealing with the Kodak -chromes in the '70s, I'm pretty happy with my non-LI cameras.  The "taste-tests" I've done shooting ...

Interesting analysis.  I'm going to use it to "validate" (well may be "just compare" is a better objective) the same analysis done in dcamprof when I make camera profiles with it. Now, I'm trying ...

Apologies for not hitting the mark...  yeah, I tend to wander a bit. That's the thing, you're not going to get to see the raw histogram until you get home and then it's too late to change your ...

Yeah, it was luck.  i didn't even know it was a thing until I started reading the manual... Thing is, you almost always need to work an image in post-processing where the exposure was pushed down, ...
