Consensual review[edit]

File:Лесопарк_Городской._Шмель_на_цветках_брусники.jpg[edit]

  • Nomination Лесопарк Городской --Ele-chudinovsk 07:05, 7 June 2021 (UTC)
  • Decline
  •  Oppose not enough in focus --Charlesjsharp 21:08, 7 June 2021 (UTC)
  •  Support Good focus body --Fernando.tassone 21:27, 7 June 2021 (UTC)
  •  Oppose Insufficient focus; noisy. A shorter focal length, lower ISO with slower shutter would help. --Tagooty 02:43, 8 June 2021 (UTC)
    •  Comment Sorry, a shorter focal length wouldn't help, provided you use a camera with the same sensor size. The depth of field depends solely on the magnification and the aperture set (Addition: and the allowed Circle of confusion). A significantly longer exposure time, on the other hand, can very easily lead to motion blur with a living insect. I cannot judge whether the lighting would have been sufficient for a longer exposure time in this situation, because I cannot see how much the "model" was trembling or shaking. I can't see any motion blur, so the photographer didn't choose completely wrong settings. --Smial 14:09, 9 June 2021 (UTC)
      • @Smial: A shorter focal length would suffer less from camera shake, hence one could set a lower ISO (to reduce noise) and/or a smaller aperture (to increase DoF). --Tagooty 13:32, 11 June 2021 (UTC)
        • It would not. Only the magnification is relevant. If you image an object with different focal lengths but at the same scale, the motion blur will also be the same. By the way, this does not contradict the usual rules of thumb for freehand photography. On the contrary, these rules are based precisely on the context I described. --Smial 01:21, 12 June 2021 (UTC)
          • @Smial:  Thanks for clarifying my understanding! You are right that for a macro shot as long as one moves the camera closer to keep the same magnification, reducing the lens focal length does not reduce motion/shake blur. I had in mind a landscape or other distant subject: the magnification reduces with a shorter focal length, so effect of camera shake reduces. --Tagooty 02:51, 13 June 2021 (UTC)
  •  Oppose per Tagooty --George Chernilevsky 05:29, 9 June 2021 (UTC)
Total: 1 support (excluding the nominator), 3 oppose → Declined   --Peulle 06:29, 14 June 2021 (UTC)
