  • Hi Benh, no polarizer, I skipped those years ago since they steal so much of the light. ;-) When you shoot things moving in water, you need to get at least below 1/200 sek for sharpness and for a bit of dof and low ISO a polarizer would ruin everything (I have tried). And no tweaking of aspect ratio (the ratio is as in raw), the proportions were already ok since the surface was calm and almost flat. Through much trial and error over a few years, I have found the perfect way to shoot things in the water. You have to wait for a very calm day with no wind (very rare here), choose the time of day that the sun will be at a good angle (non reflecting way) at the place you want to have a go at. Nearby moored boats are a blessing since the provide shade from the glare on the surface. I usually stalk things in the sea at marinas for this reason. Then you take a lot of photos, hoping that one will not have the stray surface reflection like in this photo I included for reference. So I keep an eye on the weather forecast and hope for good conditions. I've been testing this place, a marine nature reserve, since September last year. It has some nice interesting marine life. We finally had two days of calm weather and lots of sun so I could spend two rather successful mornings by the fjord. Unfortunately the eels were too deep to get good shots of. --Cart (talk) 13:01, 14 July 2019 (UTC)[reply]
  • Thanks a lot for those insights. As for the aspect ratio point, I'm fairly sure that since the light changes direction between water and air, it compress the image in one direction (or both? not sure). If one direction, as it seems on the first picture, they it might be good to consider tweaking the aspect ratio. But, just my feeling. It's not like I see that many jellyfishes in my daily life. - Benh (talk) 17:21, 15 July 2019 (UTC)[reply]
  • and under certain conditions, the polarizer "steals" mostly only the reflected light :) - Benh (talk) 17:24, 15 July 2019 (UTC)[reply]
  • I don't think it's necessary to change any ratios. In all of these photos the jelly was only a couple of centimeters under the surface, so any distortion is negligible. This is pretty much what these small specimens look like, rather flat, unless fully contracted. They don't get large and dome-shaped this far south. --Cart (talk) 17:47, 15 July 2019 (UTC)[reply]
  • Yep. They work the same way fibre optics do (or those water-filled pet bottles you see on smart-fix videos on YouTube). The sun hits them, and they light up. --Cart (talk) 13:05, 14 July 2019 (UTC)[reply]
  • I was pretty sure someone would have these two objections. First: When a jellyfish expands it kind of "explodes" with tentacles going all over the place. The tentacles are about 60-80 cm long so having the total radius in the photo would make for a really dull composition, and then I would get objections that the jellies were not the same size in the photo. The collected vs the chaos in these form a rather nice contrast to each other. Second: These guys move so light conditions and background are constantly changing (even if they move only a couple of decimeters, in this photo half is with greenish and half with bluish background). I've matched them up in the series much as I could. It's no problem fixing this in Photoshop, but I'd rather keep things as original as possible. --Cart (talk) 14:09, 14 July 2019 (UTC)[reply]
  • Thanks a lot for taking the time to explain! I no longer feel comfortable opposing but the feeling remains that the first image is vastly superior visually and the movement of these animals is not shown well enough by the second one, so  Neutral it is. – Lucas 16:55, 14 July 2019 (UTC)[reply]
