I recently bought a Casion Z750 and was wondering if any other casio owners were having the same issue I'm having. When I photograph something purple in natural light it comes out 'blue'??? What is causing this and can it be fixed or should I be returning the camera.

Is that on your monitor or on your prints???????

[magrat22]

On the LCD and it's like that when transfered to the computer.

Are you using one of the scene modes? Some have a tendency to alter the colors.

Some of the early models had the default saturation and sharpening too high – you might try setting them to -1.

If you are shooting in snapshot mode and getting blue instead of purple please attach a picture so I can check the white balance. You will have to downsize it to around 800 pixels across to attach it.

Someone had almost exactly the same post for a Sony P200 on another board and it turned out they were using scene modes.

I don’t know of anything purple around here I can take a picture of tomorrow, but I’ll look around. You were specific that the color problem occurs in daylight, so I’m guessing it is OK with flash. If that is the case it is more likely white balance.

Something you might try tomorrow is to get a white piece of paper and set the WB with the custom setting. Hit the EX button. Use the left and right to go to white balance. Go down to MWB – manual white balance if you have your tooltips turned on. It will say “Shutter” at the top. Snap a picture still in EX mode with the white sheet of paper filling the viewfinder in the light you are taking the shot in. Switch out of EX and take the shot in snapshot mode. If purple is still blue I don’t know what to tell you.

I found the MWB so I will try that tomorrow but until then I'm attaching part of a photo as all the photos I had were of the larger format and as I mentioned the problem only occurs in daylight so I can't take a photo of the object now.

Hopefully the attachment works as I wasn't sure what size to crop the pic to.

The original object is a much more vivid purple, I've attached an shot taken this evening (using house lighting) of it that's much closer to the real colour but not quite exact.

Get yourself a copy of Irfanview – it is free. Open the image and go Image>Resize/Resample and set 800 in the width with “Preserve aspect ratio” checked.

It is just about impossible to evaluate white balance with a little corner of something you can’t identify. What I can say is that your saturation is too high. Turn it down to minus 1. If that is your default saturation you probably got one of the earlier models and the sharpening is also too high. Minus 1 helps there too. That is what everyone seems to be using.

I did get it purple by just using the white balance slider in Power Retouche. If you can take a flash picture and the purple is right you are definitely not using the right white balance for the purple flowers coming out blue in the daylight.

Okay I did what you suggested but the files were too big at 800 so I've resized them to 640.

I tried the MWB in daylight and I'm still getting a blue object instead of purple??

Thx

The camera doesn’t seem to be able to figure out what is going on any better than I can. There seem to be two light sources. One warm and the other cool. The left foot on the side of the warm light is warm and the right foot being lighted by the cooler source is pink. The shot where it got the color right has one light source for the camera to deal with.

Without anything common in the picture except the edges of feet to check the WB I have no idea. I can make the ball color purple with the WB slider fully over to artificial. That would indicate the camera was using a daylight WB in artificial light conditions.

Take a picture of the ball outside in daylight with the ball relatively small and someone holding it with some shrubbery and maybe the side of a white building. You need common things in the picture to access what is happening. Meter multi and take a shot both with the WB in auto and one after setting it manually standing near the ball but not from light reflected off the ball. If the ball is blue we can look at the people and common objects in the image to determine what the camera is doing. Don’t do it within 2 hours of sunrise and sunset or there will be other variables to deal with.

In your original post you said that the problem was in natural light. Your most recent shot doesn’t look like natural light.

absolutely a white balance issue... and probably camera limitations...


you are obviously standing right over the ball... what did you do different to make the two pictures so different?

The most recent pic was taken last night the natural colour was taken using normal lighting in my living room the blue colour came out when I used flash but it's the same colour I get when I take a photo of the ball in daylight.

I've had the same problem with this colour green it comes out blue (the green in the smiley face) so I wonder if the camera is defective. Do you have this camera? If you could take a photo of something purple with your camera under natural light and post it here so I can see how your camera takes the picture then it might help me work out what's wrong with mine. The camera is brand new and I have set the saturation, sharpness and contrast to -1. I did try -2 and tried changing the numbers around in each of the settings to see if it made a difference it didn't.

I really love the camera but I don't think I could put up with it changing colour around and I really don't want to have to manually adjust WB everytime I take a photo. It's not that I don't enjoy messing around with the manual controls it's more that I paid for a point and shoot and I want to be able to 'point and shoot'.

Thanks for your help so far it's really great to get such good advice

I took another pic in daylight conditions. It's still blue

Two more pics, taken outside with tree in the background.

More pics: Same bottle, 1st pic is taken outside, 2nd inside with curtain drawn and MWB set to daylight!!

Flash, especially at close quarters will give a colour shift. but you know what, purple along with turquoise are the terrors of photography even silver halide has trouble with them. No camera will ever reproduce every colour just as you see them, in fact they rarely reproduce them just as you see them. They reproduce colours as THEY see them.

But once you realise your particular cameras limitations you can adjust accordingly. Either by playing with the white balance (which is really only effective when not using flash) or by playing with the colour later in your PC.

With the older silver halide films, most of the colour correction needed for each brand of film was done when printing. The same applies here. Just becuase you get the image straight away doesn't mean it will always be right.


...and of course everybody knows somebody who's camera is just perfect and they never have colour problems. Until they are pointed out to them.

Yeah I just tried the same pic with my Canon S200 and do ya know what the bottle came out blue!! So it's obviously just one of those weird colours that the camera can't process.

Thanks all, for your advice and help it was much appreciated

I'm so happy it's not just my camera as the Casio is the sweetest camera I've had in along time.

[PopPicker]

well there you go.

I'm glad you're happy, and you're right that Casio is just too cool.
