Hey there Apologies for the late reply. Yes I always use Peaking, it's a huge help, in darker waters I use find edges. Having a bright monitor is a must as well.

I didn't start this PC since 2 or 3 month... now it want to make updates... Let's go... I'll see what hapen Now go back to the main PC to show if...

It works on this topic.... Paste ok and I have

Yes here I see... but moment it is on the third pc I wanted to test and the paste also work

Do you see the select files to upload here or just able to paste in the screen shot?

The reflector is acting kind of like a lens, so that is not a surprise. The material of the reflector probably is not as important as the surface polish/ reflectivity.

Not all Wurkkos models are intended for video use, many/most are just flashlights. At least DL08 and DL07 are intended for video use. Topside superficial testing of DL08 gave me a promising first impression, and I have pair of those now. No diving in near future, unfortunately. They are also small enough to be general purpose backup lights in BCD pockets. DL08: https://wurkkos.com/products/wurkkos-dl08-3600lm-rechargeable-diving-light?VariantsId=12686

Actually, I DO use silicone on the rebreathers! It eats silicone for breakfast. It has lots of lots of very big o-rings in the Loop with bayonet fittings. Hoses, heads, canisters, lungs. They are all rubber/edpm and fine with silicone. This is all low-pressure ambient level so even 100% O2 is not an issue. I do use Tribolube when I service the regulators, MAV, etc. I treat all regulators like they must be O2 clean, even if some of them are just air. I know some CCR units have silicone o-rings, but that just seems like a bad idea to me.

Fishmongers, chefs, and hungry seagulls too.

Kinda wonder if Tom still has the RS. Or the Ken and Barbie dolls...... Action Man, anyone? Sorry, back to lubes.... and Retra Maxis

That - and by using Tribolube for the camera too you can't accidentally put silicone grease on something that goes in your rebreather - I've seen what happens when someone does!

Off topic - I remember the first time that someone came into Jim & Cathy's with an RS and we all were thinking that it was one hell of an upgrade from a Nik V!

.... and fishmongers?

Perhaps the reflector being made of polished stainless steel helps?

Interesting - will do some more reading once I've had some sleep!

Cheers - that might be worth playing with - I will research those!

Keyboard shortcuts and context menu, on different PC (but same OS and browser) I'll try a third but with Win 10 or 11 I can't remeber... i'll install an other browser on it, if not allready done . I'll keep you imformed. You can change the title of the subject.. I'll make a new one again when the problem is solved.

I also get the standard option for uploading an image both for a new post and as a reply like this - Win 11 with Firefox: You could always try downloading Firefox to see if a different browser helps. Did you try just clicking the page where you want to paste and just using Ctrl- V?

This is likely due to incompatible browser, content filtering (ad blocker), cookie restrictions, VPN, aggressive security restrictions (disabled JavaScript, etc) Now i do some of these things, many of us do i am sure. Carolla has found the magic combination. I suggest dropping back to a default configuration and trying again. Use a clean phone, clean OS. Maybe private browsing mode which usually disables plug-ins. Windows Sandbox or another VM with a clean OS.

Hmm, this is odd. On my Mac or on a PC running Windows 11 Enterprise, I get the usual Reply box which produces the standard option, in the grey box at the bottom of the Reply, to "Drag files to attach, or choose files..." However Carollla is getting a box with no attach files option (see below). The Waterpixels system isn't showing any errors. Anyone else come across this?

That's exactly what I use when i'm diving for macro. Less power and concentrated light

You probably don't want to do that unless the reduction ring is shaped correctly to concentrate the rays. Reduction rings tighten the beam, but if light is reflected off a white surface it tends to diffuse it a bit which spreads the beam. The reflector looks like it tightens the beam significantly and is relatively tall, the taller it is the tighter the beam. You might not want it that tight for wide angle work. I know I left my reduction rings on shooting grey nurse sharks with a fisheye and it seemed to help quite a bit with backscatter. Also you are trying to recover light from the edge of the beam, looking at some data for the retra strobe at 120°beam angle the light falloff in this region is 5 f stops. Doing some measurements on my Strobe it looks like the reduction rings restrict you to about a 90-100° beam angle. At 90 degrees the the light fall off is about 2 stops compared to the center and at 100° it 3 fstops. What does that mean there is not that much light in the outer portion of the beam to recover with a reflective inside surface to the reduction ring. - but that light is enough still to illuminate very closeby backscatter, which the reduction rings block so stop it being illuminated. so the short version of that is it seems to me there's not enough light in this part of the beam to be worth trying to recover at least on my Retras.

Agree, just because using the wrong lube gives you a problem doesn't mean that silicone is bad for o-rings. A great many housings use Silicone o-rings including Nauticam, Marelux, Sea and Sea, INON strobes - any coloured o-ring is going to be silicone. On the topic of dynamic seals, this is not insert and twist or piston style o-rings where you screw a cap on it refers to parts that are always in motion or regularly in motion, one example might be the shutter lever on Nauticam housing where the shaft rotates to activate, but even that is not really that dynamic, dynamic o-rings examples of dynamic o-rings where silicone might be a problem include hydraulic and pneumatic actuators, pump shaft seals and even scuba regulators that use a piston. On INON o-rings the secret is sufficient lube. Housings it's a mere breath of lube just to get it shiny. On INON o-rings where you are screwing on the lid, I'm a bit more generous, you can feedl the difference once you apply enough.

This is why I just use PTFE (white) Tribolube lubricant for 100% of my camera gear. As you say you can't use silicon grease on silicone o-rings. It will make them swell up, fail, and flood your gear eventually. So I just never use silicone lube on cameras. A 2oz tube of PTFE Tribolube costs about $60-$80 and will last for many years and 100's of uses a tiny dab at a time. And it will work fine on Silicone o-rings, Buna Rubber, or EDPM rings. As best I can tell it is identical to what Nauticam supplies for their silicone o-rings.
