- Support Nice pic. In terms of the image quality, I guess the thing to do is compare this with the other images on Commons in Category:Tridacna gigas. Most seem to be specimens photographed in museums etc.; there are a handful of acquarium shots, some of which are quite good, but most have a lot of CA and other technical flaws. By comparison, this is a proper underwater shot and reasonably sharp where it counts. Cmao20 (talk) 18:59, 13 July 2020 (UTC)

- Comment I would prefer to see a bit more contrast and microcontrast (clarity). -- King of ♥ ♦ ♣ ♠ 20:26, 13 July 2020 (UTC)
- KoH are you sugggesting me to adjust the settings in terms of contrast or do you mean that you'd like to see an photo with more colors/contrast (so, adjusting the settings has no purpose here)? --Poco a poco (talk) 10:56, 14 July 2020 (UTC)
- The latter of course would be even better, but I was referring to the Lightroom sliders. -- King of ♥ ♦ ♣ ♠ 12:24, 14 July 2020 (UTC)

- Comment Sorry, this bivalve does not look like a Tridacna gigas. Tridacna gigas is distributed in the Indo-Pacific region, it does not occur in the Atlantic (and consequently also not in Madeira). --Llez (talk) 20:27, 13 July 2020 (UTC)
- Llez: to be honest, I wasn't sure about the id but have searched for hours within Madeira or Atlantic Ocean clams/molluscs and haven't found anything else that could match better than Tridacna gigas. You're probably one of our experts in this area, do you have a clue or bibliography that could help me? On the Internet I have found nothing about big clams in this area --Poco a poco (talk) 10:54, 14 July 2020 (UTC)
- I just checked, which large bivalves occour in the Madeiran region. The only genus with large representatives is the genus Pinna. Considering the distribution of the different species of this genus, I think, it is a Pinna rudis, which fits also very well to the depicted specimen here. The "Pen shells" (Pinnidae) have noting to do with the "Giant Clams" (Tridacna), which occur only in the Indo-Pacific region. Pinna rudis reaches a length of 30 cm, it's close relative in the Mediterranean, Pinna nobilis about 50 cm. A Tridacna gigas can reach more than 1m in diameter. --Llez (talk) 16:06, 14 July 2020 (UTC)
- Thank you very much Llez! I uploaded the nom and the file accordingly, you are my hero! :) --Poco a poco (talk) 06:48, 15 July 2020 (UTC)

- Neutral I'm glad folks finally realize how hard it is to get underwater photos that are technically great. This is a really nice quality, and there is nothing wrong with the camera settings. However, I would prefer some better consideration regarding composition for an FP. It is harder than on land, but even so. I don't expect anyone to get it right on their first attempts (it took me some three years to get good shots into the water), but some wow-factor would be nice. IMO; you got it with the purple sea urchin, not so much with this or the green starfish. Just keep at it, it will get better. :-) --Cart (talk) 21:03, 13 July 2020 (UTC)
- Cart you don't have to tell me how hard it's to get nice picture underwater, now I feel more comfortable about reviewing them after gathering some experience. This is even more tricky than 5x-10x macro shots :) I thought though that your marine pictures were taken from above the sea. If not, what equipment are you using to get under the water? --Poco a poco (talk) 10:58, 14 July 2020 (UTC)
- Hey Poco a poco, of course I realize that you have found out the difficulties of shooting stuff under water! I was talking about voters in general here. Previously, underwater shots were unfortunately assessed the same way as photos taken on land. So progress. :-) I don't have any underwater equipment (wish I had!) so I shoot from the shore, which presents other difficulties since I have to make the surface "invisible". --Cart (talk) 11:09, 14 July 2020 (UTC)
- You should not stay with a nomination Poco a poco if the species is incorrectly identified. Charlesjsharp (talk) 12:53, 14 July 2020 (UTC)
- Charlesjsharp if Llez cannot help with that I eventually will, don't worry, this nom will not be successful without a proper ID. I have indeed invested a couple of hours to look for it and so far no success. I will otherwise ask the portuguese marine authorities Poco a poco (talk) 15:23, 14 July 2020 (UTC)
- Charlesjsharp Done we are good, Llez could id it! I fixed file and nom now Poco a poco (talk) 07:10, 15 July 2020 (UTC)
- Support After the correct identification ;-) --Llez (talk) 11:18, 15 July 2020 (UTC)--
- The fact that this is the only picture on Commons of this species (apart from dried out museum pieces) is definitely a plus for the nom :) Poco a poco (talk) 15:38, 15 July 2020 (UTC)
- Oppose per Cart. Deservedly a QI, but it just doesn't stand out enough for me to support. Daniel Case (talk) 19:44, 16 July 2020 (UTC)
