Question Red?

This is very mysterious to me. I have been trying to photograph a painting of a bowl of sour cherries, very red, stop-sign red, not orange. I cannot capture the color! I have tried different lighting, indoors, outdoors. It comes out pinkish or washed out. What could this be?

Re: Red?

What camera model are you using?

To get a deeper red you might try:
  1. Decreasing the exposure in 1/3 stops until it looks the way you want
  2. Trying a different white balance setting
  3. A combination of both 1 and 2

Re: Red?

It sounds like an exposure issue. I'm not really familiar with the algorithms used in auto exposure modes, but I believe they should replicate the human eye. If that's correct, it would tend to cause a predominantly red scene to be overexposed because our eyes are least sensitive to red. The camera assumes a medium gray, so if you have predominantly red it thinks there is less light than there actually is, and increases the exposure. It's the flip side of why a predominantly white scene tends to be underexposed. This is an educated guess. I am assuming the white balance is correct because it sounds like the issue is with the value, not hue. If I am right, the advice provided already about adjusting exposure should work.

Correction

Sorry, I should have said our eyes are much less sensitive to blue and red than to green. We perceive green as brighter than an equal intensity of red. An equal intensity of blue will be perceived as darker than red or green. In the above post I mistakenly said we're least sensitive to red, but should have said blue. Our rods are least sensitive to red, but our red cones are more sensitive than our blue cones. Sorry.

Re: Red?

It sounds like a White Balance problem to me. Try different White Balance settings assuming that your camera allows you to do this.
Otherwise I would suggest trying a photo editing piece of software such as Photoshop to enhance your colours.
There is an excellent video on Youtube by Mike Browne entitled "White Balance" which explains how it works.

Re: Red?

some camera's have to many filters over the sensor and washes out certain colors. like older pocket digi cams can't handle purple, it comes out blue, due to the UV in it, the color is always messed up.

white balance is the next thing, make sure its not on auto, use shadow or i heard if you use a custom white to shoot something slightly blue, it will enhance reds. its good for autumn shots where you don't want to do a lot of editing.

it could be that your camera is dying.

if you have raw, shoot in that and just edit it back.

do you have a sky filter on it? maybe the tint of that is throwing the camera off? and do other colors look odd? purple, green, etc? how about a range of red, like a gradient or different shades on a chart?
