All Activity

Still not able to click through to sign up for the beta (using my MacBook M4 Pro)? Edit: Just tried again and was able to get on the list.

Someone on Facebook / Alex Mustard group just asked a similar question. I'll share the same answer I posted there: The MFO-3 only exists because Sony doesn't have a decent lens in the 60mm range. Nikon has an excellent 60mm, so MFO-3 seems like a superfluous product for that system. Instead, using an MFO-1 and SMC-3 gives you a huge range paired with the native 60mm. I'd rather shoot a 60mm and use a diopter than use a 105mm and then "shorten" it with a hack like the MFO-3.

I can try it in Topaz if you like - not sure how it will come out but happy to give it a go!

Yes it's 3840x1920 but they didn't like it and while I have a collection of NLE software and even a video upscaler, I have a vintage Photoshop 3.

What are the pixel dimension changes, was it 4K footage to start with? Depending on how big the poster is, a good 4K frame should look halfway decent at that resolution.

Cheers. Good and thorough run through of various WA options and what they can bring to the table.

I have been asked for a high-resolution photo (300 dpi) for a poster for one of my videos. I only have a photo extracted from a frame at 72 dpi. I tried with an old version of Photoshop but the result is not great. Is there any kind soul who has AI upscaling software and can convert a jpg for me? Thank you in advance

Hi. No sorry I’m using Sony a7. I have only recently got the Mfo 3 so still getting used to it. I like it so far and was really surprised how close I can get the lens to a subject and be able to focus. Off out to the Red Sea soon and looking forward to using it out there

As I wrote I have that one and I've been using it for years: nice indeed but forget to attach/detach it underwater

Aloha and welcome @Rustico !

Love this option. Talked to the folks at Yellow Diving and now just have to figure out how to get it from Poland to the USA. If anyone has suggestions I'm all ears. Poland post isn't shipping the the US, UPS/Fedex/DHL Express are extremely expensive. Grrr.

Quick update. Shipped a new Mac version with HW acceleration that massively speeds things up. Shipped the new tagging structure. Working on Windows HW acceleration. Found a few bugs in the species matching pipeline that disproportionately affected certain marine species and will roll out that fix shortly. Did some tuning of the sharks and rays detector that is resulting in much better matches. Lots of little workflow changes as well. The beta is currently full but please still apply if you have expertise in nudibranchs or are into kelps/sea grasses.

Hi Ben, Welcome aboard!

Hi, I'm Ben from Switzerland. I dive since quite many years now, but mostly only a few weeks per year, like 1 or 2 or 3 weeks, depending on the holidays plans. I recently put a few of my underwater pictures online there : https://www.b3no.ch/photos/underwater/ Actually, I also put my full divelog online (the pictures of each pages the logbook themselves), and also some technical data extracted automatically from the pictures (tech data + marine life seen and other comments). This does include also some computer data, which generates the dislplay of the dive profile. Actually, I think that one of the the nice feature of this small personal website is that the photos on the site, are matching a dive #number in the divelog, and then, based on the EXIFS of the photography and the dive-computer data that are cross-checked, it's able to draw a small point on the dive-profile showing when the picture has been taken and at what depth. So those are all static data, and I have build scripts that generates the webpages automatically. The comments and descriptions are mainly in french, but there are also plenty of other data understandable for non-french-speaking person. For example this is my last dive in Marsa Nakari, south of Egypt, a few weeks ago : https://www.b3no.ch/divelog/445/ And on that divelog page, it's matching 3 pictures from the galleries. The pictures are displayed on top the divelog page, it automatically writes the depth, and then a few tech data and notes extracted from the logbook, Then some marine life information also taken from the logbook. And finally a screen capture of my logbook. My dive buddies and I love to stamp our logbooks, and especially for that last dive of the holiday week, you can see a lot of personal stamps and personal messages on those captures of the logs. Also EXIFs are available when a picture is magnified. Cheers, ben

Here a written review from Alex Mustard on the OPP: https://www.amustard.com/seacam_opp/?fbclid=IwY2xjawRWpYtleHRuA2FlbQIxMABicmlkETF5VlZybEI5M2VkM3Z6VkRVc3J0YwZhcHBfaWQQMjIyMDM5MTc4ODIwMDg5MgABHrL_VAnrzLArTrNKHmqNk-rDr0RmjPEwp192aXJj4wLj6gI8B89VBYkxx2KB_aem_JeinsEUaFTq2fWVTuFXrHg (Now the question for me is, whether and how I could use the OPP with my Nauticam Sony A7R5 housing and with wich lens - it seems to be a great alternative to the WACP-C... 🙂)

You could probably forget about macro lenses then, a 24-70 or 24-105 in a small dome sounds about right??, anything shorter focal length the performance is probably compromised in a small dome. The 180mm Nauticam or 170mm Zen is a known quantity in the port charts, the 140mm should work but you may or may not be happy with it at 24mm, which you might want if the fish let you get close. I suspect the scoot to the general vicinity and stow the the DPV might be the productive option?

I've used one of these with triple clamps on both ends and then a ball in the center to mount. It works just fine. https://ulcs.com/product/db-cb10-double-ball-crossbar-arm/ I replaced it with a marelux cross bar which is more rigid and I like it more, but likely won't work with your hand strap. The CB10 was very flexible on how it was used. It does look like your red arm is threaded - so you could just mount a 1" ball in the center and put two (maybe longer) clamps on either side and you would be golden.

Another 8-15 +1.4tc shot that I really like from God's Pocket. A close-focus-wide-angle shot of a decorator crab on a sponge. Decorator crabs have a lot of personality and cover themselves is clever ways to match their environment. These crabs are specially tailoring their camouflage to incorporate parts of the sponges they are living on. Nikon Z8 w/8-15mm Fisheye lens + 1.4TC, f5.6@1/50s iso100, Pair of Retra Maxi strobes with 4500k filters

In my experience the dome doesn't have anywhere near as much drag as the strobes and arms. Maybe because it rides within the bow-wave of the DPV? But also I'm using smaller than 180mm so far.

Welcome to the group. If you need a complete underwater camera rig, look at my posting. I am selling my underwater system because I got a new camera and housing. Again, welcome!!!

It is the Sony 20-70mm f/4 G lens. It is not of the highest optical quality (Sony labels such lenses with "GM"), but is regarded a decent performer... Here you can find serious over-water reviews of both Sony 20-70mm and the Canon 8-15mm. The reviews state that both lenses are very sharp (but one cannot directly compare the absolute values in lp/mm, since the Canon values were measured on a completely different camera/sensor): https://www.lenstip.com/643.1-Lens_review-Sony_FE_20-70_mm_f_4_G_Introduction.html https://www.lenstip.com/311.1-Lens_review-Canon_EF_8-15_mm_f_4_L_Fisheye_USM_Introduction.html My "ratings" of the UW performance of different lens/port/water contact optics combinations are based on dozends, sometimes hundreds of dives and are completely subjective. No test carts and/or measurements, motifs and conditions are always different. It is a pity that the companies that develop and sell domeports and water contact optics do not make their measurements/test chart photos, that they certainly have, accessible to the potential customers (I suspect they have reasons)... Here links to some UW photos I made with Sony 20-70mm and some other combinations discussed here: https://www.dpreview.com/forums/threads/sample-photos-from-sony-20-70mm-f-4-and-a7r5-uw.4724115/ https://www.dpreview.com/forums/threads/canon-8-15mm-fisheye-lens-with-sony-2x-tc-on-sony-a7r5-sample-photos-part-1.4779356/ https://www.dpreview.com/forums/threads/canon-8-15mm-fisheye-lens-with-sony-2x-tc-on-sony-a7r5-sample-photos-part-2.4779452/ https://www.dpreview.com/forums/threads/canon-8-15mm-fisheye-lens-with-sony-2x-tc-on-sony-a7r5-sample-photos-part-3.4779455/ No, I never used them. I could spot several WACP-1s at UW photography workshops and immediately was sure that I do not want to deal with such big staff (I find the "compact" WACP-C version already big and heavy enough)...

Very interesting Wolfgang, even though I am not a Sony User but this would supports the initial thesis of a very good air based „exit-glas“ (lens) bringing the right photons to the table 😉 Could you specify with a link which Sony 20-70 exactly you mean? Also interesting that you consider the 8-15mm a slightly less sharp performer. Have you ever used/tested WACP-1 oder WACP-2, Wolfgang and an impression on that one to compare?

Apprecaite all the advice! I will definitely make sure my camera setup and DPV and independently neutrally buoyant. They are big fish by my standards: 2-3ft (1m) in length. Planning on shooting from the scooter and also to detach and shoot but really not sure how easy it will be, how the fish will react, etc., but training should help with calmly removing the camera and re-attaching it. Based on my experience with other fish I tend to think they won't mind much but only time will tell...nothing with animals every goes accoding to plan. Typically I've shot fish with the WACP-1, I love sharp wide angle and that's my favorite lens but it's very hefty and not hydrodynamic so trying to understand how realistic it would be to use it before getting in the water and testing in the coming weeks. I guess anything will move through the water if you try hard enough :)

Macro port is pending, zoom gear and lens still available.

I'll try once more locally, if this one breaks as well then I'll consider other options. I'm not very confident the local people have their printer settings correct 😅
