Pentax 645z

G2d · 10-22-2019, 07:20 AM

Hei I'm pierre, Norwegian photographer, extremely satisfied with my Z, until today, it gives me only purple green pictures, I shoot in raw, and out just happened out I'd the blue, yesterday ok today everything purple greenish, is there a quick fix or are we talking sensorshift ? Anyone? Much anticipated, enjoy you're shootingdays

Welcome to the forums Pierre! I suggest if it is still in warranty why not have it checked in a service center? Have you checked on a PC the actual pics too?

Before concluding it's a hardware problem, it's best to rule out other problems with either the camera's white balance settings or something in the application.

Even though you shoot RAW, many applications read the white balance settings in the EXIF and apply that to the image. Try setting the white balance to daylight and see if the problem persists.

Second, it could be an application configuration issue. Does the color shift show up in multiple applications and the display on the camera?

Welcome Pierre. Just eliminate RAW processing issue, you could shoot some JPG to check that? I'm assuming you are talking about the resulting photos and not the LCD on the back of the camera?
I have heard of someone having the back LCD do something strange with this which I think was a bad contact internally - required servicing anyway.

Turned out to be a setting: cross processing, think that's the only minor with this camera, all these settings to manipulate or adjust your images, never use them, 1. I shoot in raw, tried tiff which didn't give any advantages only slowed down my lightroom, 2. TAv which is brilliant, 3. -1 stop 4. Raw button to take a digital preview, and that's it, and I love this machine, maybe you guys could start a thread: "Z settings", what are you're settings and why for your Z, thank you so much , keepupthegoodwork

Glad you found the cause!

If the 645Z is like the K-5 and K-1, you might be able to minimize the effects of unintended settings by looking at the "Memory" settings that are probably under one of the camera Menus. It controls whether the camera remembers or forgets changes to settings when you turn off the camera.

Enjoy your camera!

Sounds like a white balance issue, did you figure out the problem yet?
