So I was looking the , which looks pretty cool. However in the copy they claim that it produces images with great color.  Now if the lens glass is slightly tinted, then  that will naturally have an effect on the color. However I am wondering what other aspects of lens  design affect color reproduction.  So other than glass tint, how can one lens produce better colors than another?
It seems to me that my costlier (Tamron 90 f/2.8 macro) lens gives better colors than my cheap Canon 18-55 IS kit lens.  So does lens matter for color quality? What physical processes are involved in that?

I am generating breadcrumbs from URL arguments as described .

Proof: Show there is set of $n+1$ points in $\mathbb{R}^n$ such that distance between any two distinct points is $1$? Placing the object of an infinitive before it instead of after it I installed blender for the first time, so I have the latest version, 2.78c.  I played with it for a bit.  Then I discovered I couldn't save my work.  I uninstalled it and reinstalled it.  Rebooted.  Same problem.  After a little testing, I realized I CAN save to my NAS storage drive.  I cannot save on my C: drive.  Any project.  Any folder.  C: always fails.  If I run blender as Administrator, it will save to the C: drive.  But not as my normal userid.  So it sounds like a bug of some kind.  I am running Windows 10.  Bitdefender A/V.  I use OneDrive.  I have a 2TB drive installed.  All clean and purring nicely.  Is there a better way to install it?  Or some change I can make (other than always running as administrator)?    Sounds like a bug - but hopefully there's a proper solution.  Thanks,  Jerry I often find  syntax very helpful, e.g. process substitution like in diff &lt;(sort file1) &lt;(sort file2).  Is it possible to use such Bash commands in a Makefile? I'm thinking of something like this:  file-differences:     diff &lt;(sort file1) &lt;(sort file2) &gt; $@   In my GNU Make 3.80 this will give an error since it uses the shell instead of bash to execute the commands. Why can't a Federation Starship's transporter history be used to bring someone back to life? I've always been a little confused by the fact that when a crew member dies they don't just use the transporter history to bring that person back. I'm aware that this wouldn't make for good TV, but I was wondering if there was a more technical reason. I'm at roughly 67% completion of the Alola Dex, with ~200 caught, ~290 seen. After scanning QR codes, I've caught a Swinub and Cyndaquil. However, neither were registered in the Pokédex, since neither are Pokémon in the Alola Dex. This brought up the following question:  When will I unlock the National Dex?   Do I need to have seen all the Pokémon in the Alola Dex? Do I need to complete some specific quest, like catching/defeating the Ultra Beasts? I got a new laptop; it came with an existing Windows installation, but I wanted to migrate my current backup to the new machine. I dd-ed the new machine's partitions to an external drive:  /dev/nvme0n1p1 /dev/nvme0n1p2 /dev/nvme0n1p3 /dev/nvme0n1p4   and afterwards move my current partitions to the new machine. What followed was a medium-sized nightmare. The new machine would boot, but the wireless network drivers were not recognized and later found out (to the best of my knowledge) they couldn't be installed. I tried:   booting from the console and running:  sfc /scannow chkdsk C: /f /r /x   both seemed to have completed successfully, but now the machine would get stuck in a startup repair loop. I tried resetting the machine (whilst keeping my files), but this failed halfway through. now the machine's still stuck in the loop and decided to try and repair it externally using a bootable Windows&nbsp;10 . It's likely that I'll need the new machine's Windows&nbsp;10 key. I'm not sure if it's stored in the BIOS (it came with Windows&nbsp;10  preinstalled) or somewhere on the partitions.   How can I get the key from the partitions (if it's there at all) while booting from a Linux image? when EditText is empty and click calculateButton, app crashes $N$-body simulation in General Relativity How would one perform an $N$-body simulation in General Relativity (GR) for something like galaxy formation or galactic dynamics?  Suppose one wants to simulate the rotation curve $v(r)$ for galaxies with an $N$-body simulation, and wants to do it in the framework of GR / the Einstein equations. Is mass converted into energy in exothermic chemical/nuclear reactions?  My (A Level) knowledge of chemistry suggests that this isn't the case. In a simple burning reaction, e.g.   $$\mathrm{C + O_2 \to CO_2}$$  energy is released by the $\mathrm{C-O}$ bonds forming; the atoms lose potential energy when they pull themselves towards each other, in the same way that a falling object converts GPE to KE. There are the same number of protons, electrons etc. in both the reactants and products. I would have assumed that this reasoning extends to nuclear fission/fusion as well, but one physics textbook repeatedly references very small amounts of mass being converted into energy in nuclear reactions.  So I just wanted to know if I was wrong about either of these types of reactions, and if so, what mass is lost exactly? I am looking for a clean and fast method to force GNOME in Ubuntu 14.04 to switch between active apps only on the current workspace when pressing the shortcut alt + tab. I came to this conclusion: the primes that can't be written as the sum of two squares (lets use$p\prime$ to denote) can be written as ${p}\prime \equiv 3 \;(\bmod\; 4)$.  I need a simple proof to show this and am stuck. I would appreciate guidance! Correcting projection of 360° content onto a sphere - distortion at the poles I'm using the Autopano Giga 4.4 and Autopano Video Pro 2.6 to stitch and create spherical content, but I've recently moved into wanting to create 360° tours via Unity. I know this is partly a developers question, but if anyone out there can help me with the right specs for exporting a spherical image or video from Giga to use to create the image for the inside of the sphere on Unity, I'd appreciate it!  Experimenting with Premiere and FCPX to edit highlight reels of spherical content, I've had seamless experiences created. For some reason in Unity, the images appear to be stretched around the sphere wrong and it's creates issues on the top and bottom of the image:    The image shown is the bottom of the sphere. I'm using the Android platform to hopefully turn these tours into apps when completed. Thank you for any help! Did Snape ever commit murder? It's well known that Severus Snape was, in one way or another, a Death Eater since he was at Hogwarts. He hung out with the likes of Avery and Mulciber who became well known Death Eaters, he joined Voldemort right after he left Hogwarts, and he basically became Voldemort's right hand man until the very end.   However, in his time as a Death Eater did he ever kill anyone? We know that he was a Death Eater for around 3 years before Voldemort fell; Lily and James died at 21 and they were the same age as Snape, so it would have been 3 years since they left Hogwarts. Then after Voldemort came back in book 4, Snape would have been a Death Eater again for around 3 years. That's a total of around 6 years of Death Eaterhood with Voldemort.  So, in either of these periods, did Snape commit murder as part of his job as Death Eater? I'm not counting a certain death at the end of book 6 for reasons which are obvious if you've read book 7.   Clearly it's much more likely he killed before Voldemort fell since that roughly correlated with the period when he pledged allegiance only to Voldemort, before he became a teacher at Hogwarts. But did he ever do it? When you earn one tag badge, and then don't click "Track the next one" in the tag badge progress tracking box for a while, and then earn a second tag badge, that box continues to show "Congratulations, you earned [the same badge as before]", rather than updating to show that you've actually earned another tag badge since then.  For instance, right now  looks like this:    Even though I  a few weeks ago and then  yesterday, my profile hasn't updated to show the new achievement.  I also didn't get the "cipher" tag badge until after the 3am watershed, even though tag badges usually appear as soon as I visit my profile after earning them (for instance, I earned the "tags" tag badge on meta.SFF.SE today the very instant I clicked on my own profile there after having become eligible for the badge). Even when I went to look at the list of my progress towards different tag badges on Puzzling, which I thought would jog the system into realising I'd actually earned the badge, "cipher" still showed up as 99/100 score even after I'd gone well past 100, until last night when the badge was finally awarded and "cipher" disappeared from my list of badges to track.  TL;DR: if I don't click "Track the next one", my tag badges update slower than they should.  It's a very unimportant bug, but there must be more people than just me who like to see the "Congratulations" thing there for a while and rest on their laurels before moving on to track their progress towards the next milestone.
