Modules Development / Re: Dual ISO - massive dynamic range improvement
« on: August 24, 2013, 03:16:56 PM »
I just wanted to include my experience using Dual ISO somewhere for others that might be having the same struggle with the conversion to dng.

I am running Windows 8 64 bit which might be my problem :P.

I downloaded the cr2hdr zip folder from this post. I unzipped into the same folder as my dual ISO cr2 image file. I dragged the cr2 image onto cr2hdr and it launched, but it seemed to stop only part way through processing the file. It produced 2 files:

tmp.pgmCamera
tmp.txt

I searched for references to pgmcamera in an attempt to find a solution but found none, at first I thought I had the wrong copy of the .exe. In the end I had to run cr2hdr from the command prompt in order to produce a dng file I could use. After navigating to the correct folder just type:

cr2hdr.exe image.cr2

Where image.cr2 should be replaced with the name of the image you want to process.

you're welcome dude! How you enjoy it :)

Honestly ML is one of the best things Canon has going for them! lol! They should be subsidizing all of this and sending ML developers free bodies. In the mean time I plan on donating again. Very impressed with all the recent work.

Yea, shouldn't have sold 50D... CF cameras are boss and have more memory too :( Who would have thought.. now you can probably sell your 50D for $1k

One thing I won't miss about the 50D is how hot it got when recording video. It was hard to let it go though. I am primarily a stills shooter, and I think the 50D is probably the best cannon APS-C camera after the 7D for stills (especially with ML).

Challenge: go shoot some wonderful raw footage with your 6D and post it here: http://www.magiclantern.fm/forum/index.php?topic=5947.msg43817;topicseen#msg43817

Challenge Accepted! I haven't got a clue what the work flow for RAW video is. This should be interesting...

Great job putting this together, especially the one stop shop zip file that you keep updated! It's been a while since I was using a beta ML and it was nice to get access to everything so easily. I'm really looking forward to following the development for my new 6D. I'm already impressed with the new to me bling menu.

As an aside I think it's funny that the 50D I just sold apparently now does better raw video than this new 6D!

At this point I am trying to come up with a good reason why not send it back and so far I have not found one.  Maybe my expectations were a bit unrealistic, or I got a lemon (or a very good copy of the kit lens who knows).
 ???

The kit lens you have is already a great lens optically, I'm not surprised you aren't finding a large difference in optical quality. The difference between f2.8 and f3.5-5.6 is only 2/3-2 stop, not drastic at the wide end. Unless you have decided that one stop or so is worth paying for than you aren't likely to be impressed. Although the long end's two stops should be noticeable as you're letting in 4 times the amount of light at f2.8. Every lens is a trade off. Very few lenses are perfect, and the lenses you'll fall in love with are the ones that are perfect for your style and application, not necessarily perfect for everyone.

I think we all start out reading pixel peeper reviews. They can be misleading, and I believe they get people thinking about lenses in unproductive ways. They may feel that they need to shoot test charts to see how good their lens is :D. These lens reviews have their place, just as MTF charts can be useful. However, most of us aren't printing poster size so the actual gains in sharpness usually aren't that dramatic or useful.

I find contrast, color, flare (I shoot outdoors in bright light with off camera flash a lot), and Bokeh more useful factors, so long as the lens offers the resolution I need (the kit lens does). Think of the many great shots you've seen. What was it that drew you to those images (or videos)? was your first thought "I like that images sharpness?". At least for me, it is typically contrast, color, shape, and texture that grab my attention and make an image stand out.

I will add that I tend to think about lens ergonomics as well when I look to buy a new tool. That is one thing that the kit lens lacks in several areas, although the trade off is that it is very small and light. Also, for someone like me that shoots a lot in manual mode with off camera flash a fixed aperture lens is usually preferable. If the aperture changes than my exposure changes, and the relationship between ambient light and flash is changed. It is just a bit easier to use a fixed aperture zoom in that scenario.

I like to use zooms most of the time for convenience, but also love to shoot with primes if I can make a fixed focal length work for a given situation.

Zooms are convenient as you've pointed out, but sometimes you have to trade something (image quality) to get that convenience. If you are shooting primarily video than your resolutions are far lower than photography, so you won't be pushing the lenses you use as hard. If you buy quality zooms with good reputations you won't notice much difference in image quality. Primes have the advantage of providing larger apertures for much less than a comparable zoom. I tend to pair zooms with smaller apertures with primes that have larger apertures, but that's just preference.

You've already discovered why a cheap lens isn't all that great. The fixed aperture lenses you listed all seem like good choices if they cover the focal range you need. They are certainly going to be a huge step up from the kit lens. I haven't used any of them though, and if I were in your shoes I would look into renting them for a shoot to get a chance to compare and play with them.

You say your main issue right now is low light shooting. Just keep DOF in mind. I don't know what you shoot, but consider how deep you need your in focus region to be (maybe even use an online DOF calculator). Make sure that you will be able to get the DOF you need at the focal length, aperture, and distance to subject you will shoot. You may need more light rather than larger apertures. Just something to consider, and to use some of that 1k budget for.

User Introduction / Love the new site, looks like progress!

Hello! I just noticed this new forum!

It's been a while since I checked in on what was happening with ML. I was very pleasantly surprised to see the new web site! I was very good at forgetting where the 50D development thread was on CHDK. This will make my life a little easier. As always I'm excited to see where this project goes. I haven't made as much use of ML as I would like, hopefully the new forums and unified site will make things more accessible for the incurably lazy like myself.

Thank-you A1ex and EctaVgan for your work on the 50D port.
