I bought a Seacam PVL20 (20mm port extension) from Wetpixel member ErolE from this ad: http://wetpixel.com/...showtopic=59246

Erol was great to deal with and sent the item promptly. The item was exactly as described. I would do business with him again.

Thank you

It depends on the circumstances. You need to quickly analyze the situation and adjust the lighting accordingly. One way to quickly (maybe faster than turning a tiny knob on the flash) reduce a strobe's output is to turn it. Tilting the left strobe up could have done this. Chimping can help with the learning curve.

Using a single strobe on the right side might have helped. Or at least turning down the output of the left strobe by quite a bit. This would have darkened the left side of the pic as well as possibly enabling a shadow to be cast onto the background reef helping to isolate the fish from it.

Canon 8-15.

Using LR I was able to apply the identical fix to a large number of images in a couple of seconds by synchronizing the settings after checking off only the needed adjustments in the popup menu. One could maybe tweak the settings I used to try and crop less out of the edge. Agreed that this fix is not needed for blue images other than for getting a white rather than black background.

BTW I seem to recall that a square crop was done first - it has been a while since I did the fix! A square may be needed to get a circular vignette.

Looks like one cannot "like" an administrator's post.




Tom-was that shot with the Nikon 8-15mm?


Thanks for the tip, it is a good one. I guess we could create a circular overlay in Photoshop and make any image a circular one! Perhaps that is what we should do...


The only time it would be problem would be for competitions.


I have a (limited) selection of circular fisheye shots taken with the Canon 8-15mm. I used the Zen 4" port with a removable shade and a Canon 6D in a Nauticam housing:




I think it is subjective (and it is a blue water shot) but the edge fringing seems better?


Personally, I am not a big fan of circular fisheye so the issue (if it is one) is not a big deal for me. I am more interested in the sharpness of the new lens and its close focusing ability. Matty-I think your shot shows just how close it can focus perfectly!


I will be interested to hear how Alex and Nick got on with it is the Red Sea, and am excited to be taking it to Isla Mujeres with me at the end of the month.

The blue fringe is an attribute common to circular fisheye lens images. I provide a possible "fix" with this image. The Lightroom settings to do this are shown in a separate pic. One pic (black background) shows the same image without the fix. This shot was done with the Canon 8-15.
