Undertow

Had this same issue with my 13 year old dome. After research I got some Mother's Chrome Polish and it buffed out nicely with some elbow grease and multiple applications. Supposedly Mother's Mag & Aluminum polish works too. Chris

Hi Adam Checking if anything can be done about my account status. Nothing has migrated unfortunately. Cheers, Chris

Would be curious to see the difference in Photolab vs LR for that image, where straightening lines can be worthwhile. Though its still at the expense of oddly stretching the football & chair.

Usually use non-fisheye for people photos unless you want to make weird exaggerated perspectives. But would you even expect much UW action from 6 year olds? Will they dive down and open their eyes UW? Not sure I'd consider it worthwhile if it takes much effort. Then again, above water photos from in the water could be fun. I'd go with the 10-22 either way, shooting at 22mm for above water.

Uncorrected 100% - clearly the edges are sharper and there's more image area. Personally I don't 'see' any barrel distortion. I only see edge distortion in the 'corrected' versions. Really glad you can turn off the M4/3 profiles in Photolab. Many situations (UW especially) absolutely do not call for these 'corrections' which mostly serve to damage image quality (in this case by stretching the corners for no reason). My m4/3 is just a secondary camera, I shoot Nikon UW, but would be very frustrated if my wide shots were forcefully stretched as LR does for m4/3. A lens' distortion is its natural state of being. There are cases where its worth applying profiles to straighten lines but at the expense of image quality. More often I find it makes images look worse, but that's a personal preference I suppose. The term 'corrections' I think is a misnomer. Cheers, Chris

I know Ikelite used to sell various Ikelite-to-Nikonos sync cables. Worth a check.

Quality photography (UW or above) necessitates the ability to do your own thing. Being beholden to other people, beyond a patient and dedicated companion, mostly doesn't work.

If its a torch with no ball mount get one of these (there are multiple sizes): https://www.backscatter.com/UltraLight-Universal-Spotting-Light-Adapter-C-Cell

Using the longer arm at the strobe usually allows the strobe to stow in a better position when everything is folded up (transport, getting in/out of water etc). The strobes can 'sit' level on the the same surface as the housing with the arms folded inward close to the housing. In your configuration, the arms will have to be folded outward, protruding from the housing, for the strobe to sit on the same surface as the housing. Hope that makes sense. Not sure how different it is when actually shooting UW, I've not experimented, but I feel having the pivot point between the arms closer to the camera works well.

Hi Adam, Tim, Unfortunately it looks as if things haven't migrated over to the new account. Is there anything we can do about this? Would be disappointed to lose my status on here after 13 years. Cheers, Chris

Ya 6lbs is nowhere near enough for freediving with a 7mm suit. I'd suggest bringing extra weights and experimenting when you're in the water. As I explained in my post above, you should still be positively buoyant when you're down, but minimally so you can grab a rock and stay in place. Just be careful to not overweight yourself. I hope you're doing all this with a buddy. Chris

Yes you need some weight. You'll have to experiment. You still don't want to make yourself neutral in 2ft of water, that would be over-weighting yourself. It would also then require some physical effort to ascend - something that often churns up silt, ruins images and is just dangerous. Therefore even if close to neutral you need a way to stay down, either by continuing to kick down or holding on to a rock. A dive stick/pointer can help too. Of course never touch anything live. But then you can only shoot 1 handed so you need a well balanced rig. Chris

Hi Adam, Thanks I hope it can get back to normal, though I still see myself categorized as a new account. No idea how the 2 names thing happened but I guess that's where the issue arose I presume. Cheers, Chris

Hi Adam, Thanks for the help though this account now says 0 posts, 0 content etc and I've reverted to "Flotsam"..... Though I do see my previous posts listed under 'activity'. My old login no longer works. Would have preferred to keep my account the way it was and just change the name if possible. I noticed it at same time that the forum was updated. Maybe to do with the fact that all these years my screen name "Undertow" was different from my login name "burville". Not sure why that was the case but was that way since I joined in 2006. Cheers, Chris

FYI I've just created a new account with my previous username "Undertow", just to save the name. I'd like to reinstate it to this account. Cheers, Chris
