EOS Bodies - For Stills / Re: 1DX ISO 12,800 real-life test

After shooting around the house for awhile, I'd like to say that the AWB on the 1DX is actually really, really good.

These shots with indoor and mixed lighting where I can't use a flash are difficult.  I think WB does matter a great deal, especially if it adds a cast to a shadow that you can't get rid of.  I don't think you can ignore that.  Fortunately I was able to test both the 1DX and 5D3 in these harsh conditions and they performed similarly.

You know, you can always develop the RAW twice, once for each white balance, and then composite the one into the other using a mask and a big soft brush....

You know, you are absolutely right.  I forgot PS can do that.

I am also going to do some test shots downstairs this evening with tungsten and fluorescent lighting, and "meter" my WB reading off a styrofoam cup.  Secondly, I'll apply a flash on a second series of photos.  Funny how when you are so used to shooting in one environment you really don't appreciate the difficulties of other environments.

EOS Bodies - For Stills / Re: 60D long exposure lock-up
« on: August 07, 2012, 10:58:08 PM »
I did a 3-shot HDR in-camera sequence once, which does the 3 shots automatically.  I did -3ev, 0ev, +3ev.  Each shot required an 8 second exposure for what I was doing.  On shot 3 it just locked up and got lost and I had no idea what was going on.  Now, this is really funny, the camera knew when the exposure was overwith, so my file was fine despite the shutter hanging open.  All I did was after about 30s just fired the shutter button and it unlocked and worked normally.  This was on a 5D Mark III.

Thank you.  Diffraction was a concern, but I had to snap off the shot quickly and I was hand-holding, so I just narrowed until it was about -2/3 expsoure.  I'd love to get that situation again and do it with a tripod.

Check out the detail I was able to pull with a 400mm shot.

I read your post jrista and one minor question I had regarding your images you are observing for your arguments, what exactly do you do when you "downsize" say, a 21mp photo out of camera?  What exactly do you mean by this?  I think I know, but I wanted to be clear.  Thanks.

For white balance, your first best option is to use a styrofoam coffee cup as a white balance target. Styrofoam has a nearly perfectly flat spectral response, far superior to that of any of the commercial white balance targets. It's also about 80% reflective, which is excellent for setting white balance; low enough that there's no danger of clipping (unless the photo is hopelessly overexposed), yet high enough that noise isn't a factor. You can set it in the scene and get a nice sampling of each of the light sources by direction (say, daylight coming from the right and fluorescent coming from the left, blended roughly equally in the middle); or, you can put it over the lens and get a good whole-scene sampling suitable for an in-camera custom white balance.

If you don't have a spectrally-flat target (and note that many common "white" objects such as shirts and paper and the like are far from white), your next best bet is to boost the saturation in post-processing to 100%, fiddle with the white balance until it looks as neutral and un-saturated as possible, and then return the saturation to wherever you want it for that picture. It's much easier to tell when the white balance is off when the picture is over-saturated.

Cheers,

That's a fantastic idea.  I have tons of styrofoam cups I was drinking beer out of :)  And you're right, much cheaper.  I couldn't see the green that bad in my histogram, that's what confused me, so I will WB off the styrofoam cup, thanks.

Brian,

If I had the time and money, believe me, I'd keep the 1Ds3/1Ds2 combo and go shoot landscape for a week at a time.  It's hard when you spend all your time doing one type of shooting because money comes into play and you sort of lose some of the fun of the hobby.  But I guess it was my choice.  No demand here for portrait work as heavily as you have it; it's all sports.  There are no sports photographers to be found for universities for some odd reason.  EVERYONE is doing weddings/senior pictures, so the current demand is sufficient, but the supply of photographers is also very high.  I can honestly say that I am more skilled at sports/action than portrait/landscape.  It would take me a lot of studying and practice to do those types of works.  Weddings are a tad different as you can approach as photojournalistic. 

As you can see, I sometimes miss my histogram and WB in indoor lighting.  This is something I will have to get better at, but with gyms for basketball and volleyball the lighting is so even, it hasn't been a problem at all, whereras indoor events with mixed lighting is tough.

Basically any shot I took indoors in indoor lighting with no flash, are unusable because I cannot fix the green shadows.  I've never had this issue before I guess.

Lenses / Re: 50mm 1.2 vs 35mm 1.4
« on: August 06, 2012, 11:42:31 PM »
I did actually purchase the 35L and the 50 f/1.4 together back when the 50L was $1699 new, because I could both for that price.  I haven't been in a condition where I needed the 50L instead of the 1.4 to be quite honest.  Narrower than f/2.8 the 1.4 takes a slight lead in sharpness, even if ever so slight.  I did begin shooting in wedding receptions so I bought the 50L just to be safe and have used it effectively in low light.  But I never did a comparison so who knows, maybe the 1.4 can do just as well at f/2 to f/2.8 for reception shots.  I do appreciate the quality and extra build though.

If you already have the 50L, selling it and buying the 35L won't accomplish much regarding money.  If you didn't have the 50L yet, I'd suggest the 35L/50 1.4 combo.  Now though, I wouldn't do any trading personally.

Moral of the story is that with digital photography, shooting in tungsten and/or fluorescent lighting indoors without a flash is never, ever a good thing.
