EOS Bodies - For Video / Re: Magic Lantern... CONTINUOUS raw recording @ 24fps on 5D3

« on: May 24, 2013, 11:17:32 PM »

Unfortunately, I've been having to debug CF card issues. I'm still working on how to get 1920x1080 consistently. I can get resolutions below that, but I'm not doing all this work just to settle for a compromise! ;-)

Fortunately, there's a lot of helpful discussion going on over at the ML forums. I feel like the primary issue with the RAW hack is CF card performance. I can see why Canon wouldn't bother with this: even the top CF cards barely cut it. There are only a few cards up to the task. I thought I had a super badass card (Lexar 1000x), but I'm still having to finesse it to get 1920x1080.

Yeah, now I've run into the same problem. After recording 8-10 clips at 1920x1080 on this card it's now stopping after 33 frames every time. I have a couple of thoughts on this. I know that with solid-state hard drives the fuller they become, the slower become due to the load leveling strategies that get used and the reluctance to rewrite flassh cells until all of them have seen some use. Another thought is battery power. ML started giving me a yellow battery indicator at the same time this started. I wonder if power management comes into play and some of the hardware gets underclocked.

I'll troubleshoot tomorrow, but if you have any breakthroughs please let me know.

Okay, so I have been playing with this today after receiving my 32gb Lexar 1000x card. It's really amazing. The amount of color and detail is phenomenal. I don't think it's been posted here, but After Effects can work with the DNG files directly. So workflow is:
1)copy M00000*.RAW to computer
2)raw2dng M00000*.RAW
3)In AfterEffects File->Import->File
4)Choose the first DNG file only (this should cause After Effects to import as Footage)
5)Adobe Camera Raw opens and shows you the first frame. Tweak as needed...it will apply to all frames automatically.
5)Right-click the imported footage in the Project window and choose Interpret Footage->Main
6)Change the frame rate to 23.976(or whatever you shot at)
7)Create a composition with the size and frame rate as what you shot
8)Drag footage onto composition.
9)Render as whatever you like (I've been using H.264, Main profile 5.1 with 31Mbps average and 52Mbps Max)
10)...
11)Profit!

I will add though, working with the DNGs in Lightroom is still really useful though. I find it much easier to tweak and do cool stuff. I also created a PS Action to batch process images in Silver Efex Pro 2...that takes a LONG time, but was really cool.

EOS Bodies - For Stills / Re: Canon 5D Mk3 Reliability

Mine came in the first shipment to the US. The only minor thing I have noticed is that the toggle between Live View and Video mode is much harder to move now than when new. Anyone else notice this and if so did you care enough to have Canon look at it?

EOS Bodies / Re: Patent: Canon Foveon Sensor

« on: May 22, 2013, 10:55:16 AM »

There's another prototype of sensor (can't recall the name) that uses the energy of the photons to translate it into wavelength and then into color information.

Are you sure you aren't thinking of Roger's April Fool's Day post? http://www.lensrentals.com/blog/2013/04/wavelength-detecting-sensor-eliminates-bayer-filter-triples-resolution

Lenses / Re: Andy Rouse Reviews the EF 200-400 f/4L IS 1.4x

« on: May 14, 2013, 08:51:55 AM »

It seems like a very nice lens. I have to ask myself though, if his only other choice were using the 100-400 how much different would these shots look? Sure the ISO8000 shots wouldn't have been possible at f/5.6. I guess what I'm saying is that it seems like a lot of money to gain one stop and IQ. This lens is 10x the cost of the 100-400, but is it 10x a better lens? It will be very interesting to see what an updated 100-400 will bring.

The shots look good, man. Did you use the kit lens? This crowd would like to see some ISO 800,1600,3200, and 6400 shots with out noise reduction if you get the chance.

Pricewatch Deals / Re: Canon EOS Rebel SL1 in Stock at B&H Photo

« on: May 03, 2013, 02:01:48 PM »

Has anyone figured out if this is a new sensor with better noise characteristics? DXOMark says the T5i has identical performance to the T4i...not that I believe DXOMark testing fairly represents image quality in absolute terms... I would just expect them to show different results with a new sensor. Is the SL1 using the same sensor as the T5i?

Please let us know what you find out. I have a 400mm f/2.8 Mk II that is no longer serviced by Canon and I worry about the day when I have AF problems with it.

I updated the gallery with a two balloon shot...one with blue food coloring in it and the other with yellow.

Hey, on this subject...anyone have any ideas on variations for this I could try? I'm going try adding food coloring and then two balloons at the same time with different colors in each to see if I can get a mixing effect.

Hi all....

Thank you so much....

It was great lighting at the time.....the colour I got from Canon DPP. No Photoshop touch.

Thanks.

Andre Arment.

With lighting like that, it must have been an amazing day. Thanks for replying!

I don't know I think it's better than the original image in this thread.

if your serious then i not only pity your taste but wonder about how you can ignore the technical flaws in the composit.

Of course I wasn't Some of the people in this thread seemed to be unaware of this technique, so I spent 30 seconds searching for a tutorial that would give them the basic idea. You seemed to miss the point when you thanked me for the crap example.
