What is the difference between APS-C and Full Frame sensor? Full-frame sensors of the same vintage, and maybe same brand, have higher quality. You can not generalize this to all cases, and older FF sensor may deliver lower quality and lower quantity than a modern APS-C. |

What is a reasonable formula for depreciation of photography equipment? Minor nit: even very expensive lenses become completely obsolete, and can become functionally obsolete a lot sooner than "forever". I have a ton of pre-AI Nikkor lenses from my Nikon F days. They all still work. They will mount only on pro-level Nikon DSLRs, none of the mid or lower bodies will even mount them. And as good as they are, modern lenses have better coatings, better designs, etc. From a real world standpoint, really good lenses probably have a 20 year life. Which is a long time, but not forever. |

What photo management software would you recommend for Linux? Even when Google was actively supporting Picasa on Linux, it actually ran under WINE, the Windows emulator. It "worked" but I didn't think it worked well. |

Can Canon Rebel XS effectively optically trigger a speedlite flash? @ysap, I have not found this to be true. I have three LP160 and love them. Use them with my Canon 50D. Its true that using ETTL can be easier, but it can also fail. Manual settings flat out work. It takes a few hours of practice, but the end result is often better. Plus you will have a better understanding of light, and after all, we take all of our photos with light. |

Should I buy a camera with kit lens, or body plus lens separately? I disagree with the generalization. The 18-55 retails for only about $100, and is well worth that as a first lens. My 50D came with their 28-135, and I found that on a crop sensor body, it was far too long. I bought a 18-55 explicitly for the extra ten mm of wide angle use. Sure, its not much of a lens, but $100 is not much money either. |

Is blu-ray a good long term storage option for photos? @mlp, having a RAID system as one of the three locations is fine. But RAID is not backup, its a disk system that is slightly more reliable than a single disk. Far too many folks have lost everything when one disk in their RAID failed, they didn't notice, because RAID worked, until the second disk failed and they were completely up the creek. |

Is it possible for a hobbyist to create a lens element? Ah ah, thanks for the correction |

Is blu-ray a good long term storage option for photos? RAID is not backup. Repeat: NOT backup. RAID is useful and good, but you still need backup. You really need all images in three places. One can be your main computer. Second is another computer on your home/office network (maybe a Drobo), and the third is outside your house. Three, not one. |

Home-made snoot for macro photography. What shall I put inside? "any light"? The grid itself blocks light. The end of the straw itself has an area, and it blocks light. Maybe not a lot, but definitely more than zero. I agree, its narrower and well defined. not spread out. But it does this by blocking light that was trying to spread. |

Home-made snoot for macro photography. What shall I put inside? A grid blocks the light. It doesn't concentrate it. Sometimes you want a small spot of light, and a grid directly on the speedlight works well. |

What camera settings should I use for NASCAR night racing? I don't think a tripod will generally be useful. Perhaps if you get a 400 or 600mm lens, then you need a gimble mount. A standard ball head is not going to help much. I don't know if flash would effect the driver, but when I was racing at Charlotte, I was busy on the banking. if you distracted me, I'd probably kill you. |

What camera settings should I use for NASCAR night racing? Right, there are at least two big, heavy fences between you and the track. A few years ago, a car exploded into the fences, so NASCAR moved them back and made them thicker. For a clear shot, you have to be way up high, which means a really long lens. The Charlotte races are long, maybe 3 hours or more. Move around. Don't try to freeze cars, pan and get the motion/feeling of speed. You might even want to rent a faster body. But I wouldn't do the body rental your first race. |

What is a good cheap camera for new photographer who wants to take pictures of people at gigs, shows etc. Also street art, views? I think this is a bit broad of a brush. One can take great photos with any camera. Its the light and composition that make a photo, not the camera. Modern high end point-n-shoot cameras allow a lot of control and can shoot raw. |

How do I properly determine which camera is better in low light? @user, right. What is "best" depends on what the criteria are. For me, being able to AF counts a lot, especially with the evil kit lens that are slow at AF even in a fair amount light. |

How to Avoid Red-Eye in Photos? Preflash works for some people, but for others, it triggers a blink reflex. The most reliable solution is to move the flash off camera. |

Before buying Sony NEX 7, what other cameras I should consider within the same price? If the sand and humidity ruined your last camera, perhaps you should have protection from them as a major criteria for your search. |

Simple comparison of LightRoom 4, Corel AfterShot Pro, DarkTable I have used Darktable and Lightroom, and they have a lot in common. Lightroom has a more polished, professional UI. If you want a blow-by-blow feature comparison, you really have to give us the list of features that you care about. All of these packages have huge lists of features, and most people only care about a subset. |
