K-70 metering issues

good morning (-:

I have recently bought a refurbished K-70 camera and a sh Tamron 90mm macro , very pleased with both.

However I`ve shot some flowers this morning and find all shots to be overexposed.
I used matrix, -1/3 exposure, single spot AF , neutral.....

A lot of the shots had Daisies which made me expect the camera to under expose (certainly not to over expose).
The files are usable as they are only overexposed by 1/2 to 1 stop (in my opinion) but it still seems odd to me !

Can anyone see in the Exif data what`s wrong or has any other Pentax relevant info ?
Many thanks !!

This shot looks perfectly exposed to me. Is it your monitor perhaps?

Yep, the histogram shows no overexposure at all.

If you are capturing images in the camera JPEG file format, it might be worth doing a Reset to get the camera back to its default settings if you have not yet done so (see the Spanner Menu 5). Then go through the menus to set up the camera as you wish - it is worth experimenting with different parameters and costs you nothing except some of your time.

thanks Adam !
I`ve emailed the image to a friend and checked on his pc and indeed it looks very different (less bright and more saturated), I`ve done some adjustments to my pc screen (-:
I knew the colour was off on my pc but never noticed it being too bright until today !
Many thanks (-:

Most consumer monitors and TVs are usually set too bright for photographic use. They need to appeal the average user, who wants to see movies and videogames.
I think it's almost mandatory to profile a monitor in order to use it for photography. It's kinda easy with a calibrator, especially one which can check luminance (good values for post processing are around 120 cadelas per square meter, which will probably look kinda dark to you at the beginning).

Regarding saturation, I feel this picture could do with a little bit more, but apart from that I think it's fine

thanks LensBeginner !
my laptop only allows for basic adjustments )-` but it`s better now then before.
The image is off course straight out of the camera... and looks now actually very nice (as base).

Almost every single image viewer has a histogram function (even IrfanView or FastStone).

Downloaded your image and opened it in Silkypix Developer Studio Pro. As mentioned above, any decent image editor will allow you to do the same.

see Menu

This is a lens effect to camera, return to zero EV.

From menu - custom image the default is bright, try other selection.
