No matter what white balance setting i choose at iso 1600(low light)no flash my pink floral bloom comes out red. using canon t4i. Standard style. Why is this happening. I know i can correct this in lightrm with a hue setting,but i wish to have it come out correctly out of the camera. Any ideas. Thanks!!

What's your saturation set to?

You may be under-exposing. Have you tried shooting in daylight next to a window? Do you have a pic you can post to this thread? Click the "store original" box before attaching.

In the meantime, make sure you understand how each WB choice affects your image, based on the light source:

Is pink-to-red the only problem? Do the greens look correct? Other colors in the images?

my saturation setting in the standard style is set to zero. Thanks.

Linda thanks for the tip. AS today is a cloudy one, on a bright day i will follow your tips and see what happens to the color of the christmas cactus bloom. In auto white balance the flower still comes out as red. also in using flash and the wb on flash it still comes out red.

While it will not necessarily affect the color I would at least shoot at ISO 100. Use a tripod, aperture priority and let the camera set the shutter speed. If nothing else zero noise. You are shooting inside so what is the light source inside your house? Unless you are using a softbox(s) etc. you can only guess at color balance setting. Are your lights florescence, Incandescent, ambient, a mixture? In general, many sensors are not good with reds. Seems like an awful lot of time and experimentation for SOOC. Would suggest you shoot raw,tripod,auto WB and dial in the exact kelvin in LR.

Potential problems:

White balance error, and/or exposure error — Solution is to use an exposure and white balance target and a Custom White Balance. This works for both raw and JPEG capture. Act like you're using JPEGs, but process raw files on a computer with a calibrated and profiled monitor. When processing raw, the white balance reference made for the JPEG exposure will usually prime your software with a very close starting point.

Monitor calibration error — Your computer monitor is one of the most critical tools you have for achieving accurate color. You need a good one. But besides that, you need to calibrate it with a HARDWARE device (colorimeter or spectrophotometer) and associated SOFTWARE. Don't rely on the operating system's "eyeball it" calibration routine. Simply explained, CALIBRATION linearizes the device, meaning it reproduces gray as true neutral gray from pure black to pure white. It does that by getting all three colors to produce the same output from the same input. THEN, and this is the most important part, PROFILING calculates the exact capabilities of your *particular* monitor, and stores a 3D lookup table in the computer's operating system. That ICC Profile allows the monitor to display color in reference to an INTERNATIONAL STANDARD that all digital color devices should be calibrated to meet, if they're going to display accurate color. Profiling and calibration are necessary because no two monitors come from the factory with the same calibration or profile. Then, as you use them, their color "drifts". So periodic re-calibration and profiling is necessary.

Subject Failure — Certain flowers appear one color to our eyes, but are recorded as a different color on film or digital sensors. This is due to fluorescence of chemicals in their petals. The minerals reflect UV or infrared that the camera can see, but you can't. That biases the exposure of the color, shifting its hue.

Color gamut inadequacy — If you're saving JPEGs in the sRGB ICC color space (gamut), then you may be trying to record certain colors that the sRGB color space cannot contain! These are usually highly saturated colors that come out dull. I notice this quite often when processing my raw files to sRGB. They look great in Lightroom, but when I soft proof them on screen, they look dull. An 8-bit sRGB JPEG converted from the raw file looks equally dull. Prints made on a high end printer from Lightroom look better, but can be limited by the color gamut of the printer/paper/ink/printer driver combination in use.

Try using an clear infrared filter. There are plants, like Morning Glories, that reflect infrared that make it almost impossible to correctly get the color right without a filter.

Hey, thanks for all the tips ! I managed to correct this color problem by changing my white balance to tungsten and it did the trick. I just might have to tweak it a speck
in lightroom. Thanks all!!

What do you mean by Pink? Pink - Desaturated Red; or do you incorrectly mean Magenta, as some people do. That is a totally different (subtractive primary) color. I shoot Raw and can usually fix WB issues with Adobe Camera Raw with on click, should be the same in Lr, but try the WB / color temperature slider not the Hue. Also, an 8-bit JPG might never be correct for some precise Hues, Tones, and Colors.

Cool, I'll have to try shooting Morning Glories with my IR Converted camera so I will get more effect. Usually only leaves are huge IR reflectors.

What sort of conversion did you get? I know there are at least three different setups you can have.

665nm. I usually do the Ps channel swap to get blue skies and yellow foliage. But the point was many flowers are little different in IR vs Visible, so I'm glad to know Morning Glories might be a good subject for IR. I'll also often crank up the contrast and go to B&W IR PP. I should try but have not with a converted digital camera, put a glass 720 or 900 nm filter on the lens as well and go totally B&W IR! I own a lot of IR passing filters from my film days. Now UV that is a crazy world of color I with I could really get into.

Some camera setting like white balance do not carry over to third party software like photoshop. If you use DPP4 software supplied by Canon all settings will be recognized in the conversion. Picture styles,Auto lighting, high ISO noise reduction are other features that do not carry over and are lost. Shot raw and use DPP4
