*ist DS colour issue


Link Posted 08/09/2019 - 18:32
Hi all,

I am having a problem with my Pentax *ist DS, which I've owned since about 2006 or so.

I took it out the other day to take some photos of a car and it wasn't until I got them onto the computer that I noticed they all had a weird pink tint to them. Any ideas? It seem to do it in all WB modes (this was taken with AWB) including manual. It was fine the last time I used it, never dropped etc and a fairly low shutter count (3422)

Any ideas?

ETA - the car should be a darkish blue and the wheel should be black.

Can you upload the original jpeg, straight out of camera (not one messed about with in Photoshop?)
Best to eliminate processing issues first.

Also try doing a default setting on the camera to see it that resolves it ('Back to initial settings'.)

Is this closer?

It's closer, although the shade of blue is slightly too light and there is still quite a pinkish tint, most noticeable on the wheel and the wing. It was taken in bright sunshine with nothing magenta / pink etc anywhere nearby,

The pic I just found online gives a better idea of what the colour should be

Here is a link below to the original file straight off the memory card - I can't upload it as a jpg straight from the camera as I take all my pictures in raw. The only think I had done to the one uploaded previously was to save it as a jpg. This is happening with all pictures in all settings.

Just downloaded the PEF and my prog says it can't process the file - sorry!

I opened the PEF in Silkypix and the green channel is much less exposed than the red or blue. I fear your camera has become an ornament.

The colour balance does seem way off. Have you tried the default setting to see if that resolves things?
Also try a few photos just in auto, if they all still come out with that magenta cast it suggests a fault with the camera somewhere.

I was worried it was a physical issue too, but hoped there was some kind of daft setting I had changed, admittedly not something I look for much online, but the entire 'green' sensor part of the CCD failing in one go seems a bit odd.

Just in case, here is a link to .jpg version link

and a 'photoshop raw' version (.raw) link

It wouldn't be so bad I guess, but the other *ist DS body I have is in worse condition, but works perfectly (apart from fibres and dust on the focussing screen) and this failed / failing one (a silver and black one) has more sentimental value than the still working black one (which has a mere 2001 shutter count it turns out).

Also discovered on one of my spotmatic F cameras the battery tab was corroded to the cell, so came out when I took the cell out and on the other one the mirror keeps sticking up and even when gently persuaded down just pops back into the up position.

So far I haven't been brave enough to check out the MZ-5 I have in the bag - I'm thinking it'll probably catch fire or something....

I shouldn't have tried to take any photos this week!

I wouldnt bother with a lottery ticket this week.

The DS is a fine old camera. My first DSLR. It's small size and great capability makes me regret I sold it. However DSLR cameras are so much more reliant on the electronics than their film predecessors, and therein lies their problem. There will come a time when some part of that electronic wizardry says "no more". Then you are stuffed.

I took my DS out of the drawer the other day, put some batteries in and ....................................... ! It's dead.
Both the *istDS and the K5 are incurably addicted to old glass

Must have been a bad week for DSs.
