  1. Has anyone entered general photography competitions with underwater images? (I mean not underwater photography competitions just general ones) I am interested in this as generally I prefer to create images that anyone not just divers or uw photographers like
  2. Yes I agree on the principle nothing is a must but most things are helpful Housing ergonomics are essential for example this Zcam set up that shoots RAW requires a monitor I wonder how that works underwater as the rig is taller than is wide? There have been posts here on RAW and how is going to be a game changer so I started looking into it, that does not mean I am fully convinced but certainly will have some benefits. I am also taking pictures so I am well aware of what raw can or not do. The thing that is becoming apparent is that RAW for consumers has limitations (12 bits) that make it more suitable to smaller formats such as MFT than larger that will then crop to 4K or loose the dynamic range they have in the process
  3. Yes there is a definition RAW is unprocessed sensor data at the bit depth of the ADC in the sensor. You then have lossless and lossy RAW. BRAW is none of either is just a video codec with high bitrate andapparently uses the same DCT that prores uses. It may have the headroom but it locks you down to a single product and vendor more than ProRes RAW does. In this respect is the same as proprietary RAW formats like Canon or ARRI but it is not RAW so really I do not see much point in this. I am not sure you can make a call from gopro to BMPCC if you have not used a camera that has it? I have tried all of them and IBIS has his merits together with the ability to make changes however this is not substitute for correct exposure and light All those things help Currently ProRes RAW is the only RAW lossy offering that is available at consumer level and is also very efficient as it compresses sensor data the bitrate are manageable with current equipment. One concerns are royalties only atomos is willing to pay them but their supported camera list grows everyday The only non pro camera right now that can go underwater and records RAW is the Zcam E2 all the others don't have RAW
  4. This post may be of interest. In essence the only thing that is RAW about BRAW is the name. It is just a video codec http://www.bmcuser.com/forum/blackmagic-camera/general-discussion/22868-oops-braw-isnt-raw--its-a-ycbcr-codec
  5. Braw is actually video not raw as it has already gone through demosaic and is only supported by their own program. It is also lossy and I am not sure I can back up most of the claims about the various format and the efficiency as their algorithm is proprietary and not documented so I left it aside. I believe being linked to a single brand and not able to go mainstream is a major limitation. Right now is unclear how much more headroom raw provides compared to a high quality video codec like ProRes 422 HQ and this is possibly camera dependant We need more footage and with cameras like Zcam and Panasonic S1H supporting it we should have a better base It is not possible to draw accurate comparisons with raw images because in camera jpegs are 8 bit and many cameras shoot 10 bit video that can take much more changes in post Sent from my iPhone using Tapatalk
  6. I like smaller housing and ultralight handles compared to Nauticam This is not an option for large rigs but for small ones is much better and the housing is much more compact Sent from my iPhone using Tapatalk
  7. There are some serious issues with ProRes RAW and the nikon Z series http://blog.falklumo.com/2020/01/the-conundrum-of-nikon-z6-prores-raw.html Right now ProRes RAW is better on MFT other than of course ARRI and RED Sent from my iPhone using Tapatalk
  8. I was quite harsh with the camera and this was due predominantly to an issue of moire Since then Nauticam has not sent me any product for review lol. The housing was really nice but it defeats the purpose of a compact rig. I would recommend you buy the camera first try it and then check out the housing. Most features can be tested on land
  9. I have shot the Sony RX100 and other Lumix compacts since 2012 all the way to 2015 when the concept of port system needed introduction and compact made no longer sense In terms of the requirements you have (white balance, battery life) I would recommend you stick to Panasonic For what concerns autofocus, low light capability there is simply an issue of sensor size and technology So while Panasonic has MFT compacts and Sony has 1" sensor you need to consider that Sony compacts are back illuminated so at the end they are pretty much equal Consider that Sony simply does not white balance underwater and the ergonomics and color accuracy are the worst on the market but on the other hand the sharpness and focus is brilliant I would consider and test the Panasonic LX10 that has a fixed port above all others
  10. I have a mixed approach I use Lightroom 6.14 non subscription (probably will die when I change camera again) together with DxO PhotoLab 3 and a bunch of other programs I bought for land photos. Now that I know better I found that at least for MFT format the RAW engine of Adobe is average and the colour rendition quite average too. So I use lightroom as a catalog and then when there is an image I really like I do the RAW processing in PhotoLab this creates a TIFF that I can further process in Lightroom or other plug-ins. One things that I particularly like of other plug ins is the ability to change the colour rendering of the camera or to overlay an xrite calibrate rendering that eliminates what the manufacturer or adobe think is correct from the mix In terms of catalog management and metadata edit lightroom is unbeatable so it will stay there for sure for a long time
  11. I got hold of ProRes RAW clip from Zcam and checked it against log compression https://interceptor121.com/2020/05/23/do-you-need-raw-video/ Read the whole article. From the limited sample it seems like the case is small for MFT but potentially more interesting for larger sensor
  12. This camera has the same sensor of the Panasonic GH5s and records to SSD ProRes422 HQ. There is an upcoming functionality to record ProRes RAW using a Ninja V (the camera has no LCD so it needs a monitor anyway) Nauticam makes a very cost effective housing (but you need an housing for the monitor anyway) Drawbacks like the BMPCC no IBIS, lack of control, probably no custom white balance, proprietary software to decode their Zraw files (if you don't like ProRes RAW) I would be interested in some real life experience the housing is really compact (as it needs a screen)
  13. Am not saying is not possible am saying it deteriorates quality If you want to deliver 4K use 4K in camera or crop it will have less arti facts So who watches anything in 3:2 aspect ratio? Nobody Who has a 20 megapixel display? Nobody There are already too many pixels display manufactures and Tv are not pushing for more pixels but for HDR This is why super35 sensors are still around as they give excellent quality for 4K without messing around Sent from my iPhone using Tapatalk
  14. No I did know it this topic came out in a GH5 group and same misconceptions This sensor doesn’t have enough processing nor pixel to do anything so it crops to APSC and so you do from 6K because 6K is 3:2 aspect ratio And you would have to crop and drop pixels too Full sensor is still slow those cameras don’t do more than 30 fps at full rez and have plenty of rolling shutter Really not much point and am done with this discussion Sent from my iPhone using Tapatalk
