  • the suggestion about using a 3rd party partitioning tool makes some sense, but if it tells you the partitions are all OK and W10 still can't mount/read them then it still doesn't solve your problem. ...
  • this sounds similar (but not exactly) to a thread here a week or so ago where a guy's USB drives stopped being recognized by W10 after an OS update. He had the same symptom where the drive is ...
  • Many technical people end up learning far more on the job the first few years out of school than they did while in school, so the discussion isn't as simple as what curriculum to study in college, ...
  • I think the general message regarding how product engineering actually works has been covered well, a few more comments that I'd like to add. 1. products get more complex over time, so if you stay ...
  • its kinda funny how an obviously sarcastic one-sentence generalization is taken seriously/literally by a couple of people.
  • you answered correctly yesterday, with 55mm.
  • if I have a 24MP sensor with a 50mm lens, what is the effective FoV in terms of focal length if I crop the image to 20MP??
  • the big difference is the brain translates things for the eye that it really doesn't see, based on experience.  The classic example of this is the cube with the same shades in the shadows and in ...
  • But this is a forum of engineers, not photographers, so the analysis of the equipment is the main purpose, taking pictures is secondary.
  • re-shooting is probably the best solution, but if that's not practical then one option would be to copy one of the flag/banners from the left side and try to reverse it and place it over the idiot ...
  • I guess you changed your mind because a couple of replies earlier you said this: "I could also go mirrorless and jump to Nikon but don't particularly want to do either of those. Mirrorless has some ...
  • So now that you're back and running, if you're not doing OS image backups then you're just asking for trouble again sometime in the future.  Fool me once... fool me twice...
  • Replied in History
    poor choice of wording perhaps, but as I said before, you lose something on the wide end with FF lenses, which are your only option.  The 16-35 and 17-40 go no wider than 21-22mm equivalent, and ...
  • maybe it is, unless she has an old 4:3 computer monitor @ 1024x768 or something.  What other viewing format uses 4:3 aspect ratio? OP, what's your viewing device for the final video?
  • Replied in History
    the reasons the 1d2n isn't of interest today are several: 1. no support from Canon, if the shutter breaks you have no repair option so you throw it away 2. the batteries are big, expensive, and ...
  • google "perspective correction" for any pixel editor like photoshop, etc. I use it for wide angle architectural shots, it improves tilted buildings fairly well, but its not perfect.  Not sure how ...
  • yeah, I took a quick look there and didn't see it either. There were 3 different 18-200 versions, not sure which you have, but they all had similar transmission levels. I think the way they spec ...
  • when Canon designs a system, they design it the way they want to, for whatever reason they want to.  Their only goal is to make their lenses work on their bodies, so the mount doesn't have to be ...
  • So if I understand your OP correctly, you shoot in manual mode, and the two lenses provide slightly different image exposure brightness when the camera is kept at the same exposure settings, right? ...
  • OK no need to examine the partitions then, that part is known. I have no idea what to do next, other than give some advice about doing system image backups periodically.  If you do that after this ...
