Inaccuracies in color photos, or.....


Recommended Posts

Okay, here's my question: I have an Olympus camera and a Powerbook G4 computer, and I take pictures all the time and download them to iPhoto, and then to Villagephoto so I can post them here.

I take a lot of shots of my yard, and most of the time the color renditions are pretty accurate. (At least, they look good on my screen.) But right now I have this purple clematis blooming, and it looks blue in the photo:

P7080092.JPG

Now, right after I took this shot, the little monitor on the camera showed the shot and it looked blue, not purple---so I wasn't surprised that it looks blue in iPhoto.

There must be a technical reason for this, and I'm hoping that someone here can explain it to me. I took color theory in college, so I understand colors reacting to each other and vibrating colors and all that. I also have an SLR camera and I know about using filters and how different films react to colors. But this has me stumped.

Ya know Olga,

I have used Photoshop for so long, I don't even bother worrying about that kind of thing. I just adjust the hue later. Not exactly helpful for you...BUUUTTTT...the newer versions of iPhoto have many similar color adjusting features. The ADJUST button is off to the RIGHT when you double-click on a photo and it zooms in on just that image. Use the TINT slider to get it where you want it.

Now...as to the reason...are you using the flash? Is the camera set on autoflash? The "color temperature" of the flash can change the hue of whatever you are shooting. Try shooting your photo with the autoflash OFF.

Does any of this help??

Heh, look who's answering. Big complex topic here that cannot be answered simply. Basically Digital cameras use RGB sensors and there are clearly problems in reducing the world to Red Green and Blue. If you have photoshop you can tweek your colors. Google "digital camera color problems" and you get a couple of good hits on pages where you can read up on what's going on and how to play with White Balance to help.

Why does it happen?

The camera's computer chip is programmed to average the colors with the intention of avoiding gross color errors.

Back in the days of real film cameras shooting black and white, we used to talk about an 18% Gray as being the average shading for black and white photos. I have no way of knowing what your camera is designed to do.

As Wifezilla mentioned, a photo handling program is the only way to fix this. Although, if you have a more complex camera you may be able to find a solution by selecting different shooting modes, e.g. Night closeup vs. Daytime Indoors Fluorescent.

One other thing to keep in mind is that the monitor, the photo display software (IE vs, Foxfire vs proprietary software) can affect what you see, even with the same file.

Good luck.

Thanks, gang: don't have PhotoShop, don't have recent version of iPhoto. There's no color adjustment in the version I have. (And I'm unemployed, so I won't be getting iPhoto 6 or whatever the new one is!)

I will try one in brighter light tomorrow without the flash.

Bobby, if you PhotoShop it again, it's a deeper purple.....heh

does it have settings for different types of lights? or a "vivid" setting, etc. sometimes the color in my camera gets off so i do a manual white balance against a white surface in the space i'm taking pictures in and that helps get the colors right.

I think you needed more lighting and less flash (or more distance between the flash and the flower). About every color

tweak I tried on the picture made me think of a reflecting glare back off the petals.

Hm. Life can be so much harder with a hackintrash ... gimp or xv in theory could help.

Hey, you disrespectin' my 'puter???

Nullo, I know you're trying to be helpful, but I am a middle-aged woman with the barest of computer skills....and I haven't got the foggiest idea what those gimp or darwin things are. Or how you get them. Or what you do with them. But I thank you for the thought......

I am severely technologically handicapped, which is why I posed the picture question in the first place. I'm the only person I know who doesn't have a cell phone... :) And it's also why I like my mac. It doesn't get viruses and it doesn't crash and I can actually use it.

And it's pretty. ;)

Wifezilla--you will hear from me.

Don't Dis da Mac, Jack!

I am actually computer bi-ligual. I use both a lot. I HATE Windows!!!! And most Windows users shouldn't be allowed anything more complicated than a pocket calculator.

Sure, there are plenty of very competent Windows users....but these people talk their non-techo friends in to buying a Dell or having one from scratch. And at the first sign of a problem, their technowiz friend who talked them in to the purchase is nowhere to be found. So they call me after their kid infects the entire machine with viruses for the 20th time. ;)

I always tell them.... "Didn't I tell you to buy a Mac?"

them: "Well ya...but..."

Me: "Based on the errors you have, you need to reinstall your operating system"

them: "But I don't know how!"

Me: "Well, the guy who told you to buy this..can he help you."

them: "I can't get a hold of him."

:)

Side note, my 8 year old Mac is still working and is a functioning part of my office. So is the 6 year old mac and the 3 year old mac I have (as well as my 1 year old iMac flat screen and my other iMac...LOL). I have a LOT of friends with 2 year old Windows based paperweights :cussing:

Ah but those paperweights have cost me about what Apple charges for a mouse pad. I hear that the new Mac OS can run Windows programs, wow you guys will finally be able to do some computing on those pieces of sclupture that light up.

Huh. Most distrubutions for Mac include binaries for download and install. Yep, looks like the "free as in beer" software

that I know of ain't for you.

Macs *used to be* the only damn computer I'd worked with that could get a virus from loading a text file. And the

Mac users I'd get in the computer lab I temped in were the most brain-dead... they would literally come in, drop

their books on the desk and say "Mac." (Maybe it was because I worked the closing shift at that lab... the dumbest

were in fact PC users.)

Then along came Windows.

As far as pretty - mine glows blue! (Why this is important enough to throw into a base tower case I have NO idea)

Buying from scratch makes a lot of sense if you don't really have to replace everything. It's stooopid to replace

the whole computer if all you need is another hard drive for your porn and mp3 collections or more memory.

More than a few years old - buy a new base computer and swap the custom gear if you have any. Use the old

computer for something gentle - like a big honking fileserver for all the porn and music files. (This was, I think,

easiest on the Mac if you could afford the drives, but it's not too hard on any of the major desktop OSs now)

I have an 18 y.o. PC that will still boot up if I hook it back up. But now a $50 postage stamp-sized chip of plastic

carries 32 times the amount of storage that the $300 hard drive for that puppy would hold.

<giggle> Yeah, when this computer gets too old, I'll get a new one and keep this just for my porn files.

heh

Comments like this always jolt me back to my first PC with 1/2 a meg of TOTAL memory (not ram) and it's HD was a cassette tape recorder! (hell it ran on steam, had to shovel in coal through the 5 1/4 " floppy door!)

Oh lord I'm old.

Olag, you're putting me into a near-terminal blush with talk of porn, stop it!

Namaste,

Bobby

My first computer was a Kaypro II. It was supposed to be portable but weighed like 50 lbs. You could only program on it in basic. Your removable disk were the size of dinner plates. Yup...I'm old.
