In Topic: Dome reflection ?

01 January 2015 - 11:03 PM

It's a problem that occurs with acrylic dome ports when sunlight hits the port at a certain angle.


I've seen it when I'm shooting my fisheye zoom and point the camera up towards the surface and sunlight. I don't get it all the time, but sometimes it shows-up. Someone told me glass dome ports don't produce the same issue. The same source suggested the use of black gaffer's tape  on the reflected surfaces of the lens eliminate the problem.



In Topic: GoPro Hero 4 Silver, 2x 2500 lumen lights, filters, etc...stick to video or p...

I think you posted a similar question about lighting for video without the sample photos on another forum.


A couple of the photos you posted here illustrate shooting beyond the reach of your lights. Your filter will compensate to some extent, but you'll see better results if you get closer. Attempting to shoot subjects beyond the reach of lights is a common mistake; I still try to push beyond the limits in hopes of getting lucky more than I should.


Keep in mind that the GoPro shoots at a significant wide angle, and it doesn't focus on things that are closer than twelve inches unless you've got an accessory close-up lens installed. Stills are captured in jpeg format at 12 mg pixels which is on par with many point & shoot cameras. Many of us use systems that record in RAW at higher pixel counts. RAW allows for lots more editing


Your turtle photo captured good detail and its fin that's out of focus is simply closer to the camera than the lens can focus. If you haven't tried tweaking the sharpness with your photo editing software, you might give that a try.


GoPro's have come a long ways since the company produced and marketed its first model. Lots of folks have been producing some very good quality underwater images and video taken with their GoPro's. Like any piece of underwater photo/video gear, there's a learning curve that accompanies using it effectively. Invariably, when someone posts a really clear video shot with a GoPro, people always ask how the heck he/she did that?


I received a GoPro 4 for Christmas and played with it while diving in Kona last week. There's a lot I need to learn about it before I produce anything worth posting. I'll probably sign-up for a class. Part of the magic involves getting the settings on the camera configured correctly... it's not rocket science, but I need some help anyway.


Once you've got the settings configured, you need to get out and shoot pics and video to see what works.



In Topic: D7000 Ikelite, buttons on camera not working while at depth

14 December 2014 - 06:59 PM

Hopefully, you've resolved your issue by now...


I encountered a similar problem with my Ikelite housed D7100 when I first started using it. The camera would shoot, but none of the buttons would work.


In my case, the spring had slipped off the shutter lever and the lever was putting enough pressure on the shutter button to prevent the camera from functioning like it should have.


Hope your issue is as easily resolved as mine.



In Topic: Ikelite 161 or something else?

I've no personal experience with strobes other than the pair of DS161 I currently use. The units are kinda clunky and heavy, but I've managed to get decent (In my humble opinion) photos with the strobes.


During a recent trip to La Paz, Baja California Sur, I did experience a failure with one of my battery packs. This left me with one working strobe for most of the trip. The one strobe that worked provided enough light for me to get workable images. I guess output with DS161's is as good as other strobes if positioned correctly. Check out the La Paz Folder in the portfolio section of www.cortezbluephotography.com Most of the photos were done with a single strobe.


Power consumption is probably not a major issue for you, but for what it's worth... A couple of other photographers in my group were using other strobes. They were changing batteries after a couple of dives every day. My DS161 battery lasted all day.


I'm not sure what happened with the battery pack that failed. Ikelite backed it with their warranty and requested that I return both battery packs for service. They repaired the one that failed and serviced the one that worked.



In Topic: Macbook pro retina and photos editiding or PC

24 November 2014 - 09:34 PM

For what it's worth, I switched from a PC to a MacBook Pro with retina this past summer. The color thing is a non-issue for me as I'm totally colorblind. Image clarity is more of a relevant issue. I've been pleased with the retina.


I didn't comparison shop much before purchasing the MacBook Pro. The digital printing outfit I use to print my photos uses Macs. When I edit on my MacBook Pro, view the photos I'm having printed on one of the firm's big Mac monitors and have the images printed on high quality paper, the photos look exactly how they look on the monitors.


Since I'm colorblind, my wife is my color editing resource. She really likes the retina on the MacBook.


I've got some video footage that needs to be edited, but I've not messed with it yet.
