EOS RP - why blue tint using the adapter and EF 24 F2.8 mm IS USM lens?

Hi!


I demo'd at a photo store the EOS RP, which feels just great in my hands. I demo'd using an adapter and my EF 24 F2.8 mm IS USM lens.  One of my questions is:


Why did the photos come out with a blue tint (see photo - only change I made was to decrease the size)?

Color representation per image properties is sRGB.


I am hoping this would be an easy in-camera correction.

Thank you and all the best!

What was the white balance set to?  Perhaps it was on say Tungsten (3200K)?  For a bright sunny day, the color temp would be closer to 5500K.  Lower values would add more and more blue.

 

If you captured the image in RAW, you can change the white balance in post easily.  For example, in Adobe Lightroom, you could use the white balance eye-dropper tool and click on something that suppose to be white or gray.  e.g. the snow.   Or, manually adjust the color temperature slider.

Do you have any other photos?  I think it looks pretty normal for a blue building in the shade under a blue sky.


If you look at just the area to the left, it doesn't look so blue.

Hi,


Thank you!

 

Here it still seems blueish in the building, the snow (the snow is understandable though since over exposed)

Perhaps it is my montor - I will be upgrading!

 

Thank you for your help!

Thank you!

I do not know what white balance was set to (I only demo'd it quickly and don't have it here) -- and it does not show up on my computer under image properties.

 

I appreciate the suggestions on editing in Lightroom!  That sounds like a great tool! I will likely use Lightroom too once I upgrade my PC -- just using a freeware Photoshop now and haven't used its full functionality.

 

All the best to you!

Annie

Lightroom is nice to have, but not mandatory.  The Canon DPP4 software can process RAW images, too.  The biggest advantage to using Adobe LR is that it can perform lens correction on third party lenses.

Annie,

 

I will suggest the problem is using CS2 and "manual" WB setting.  CS2 might be too old to render the RP correctly.

Annie,

BTW, you gain nothing by saving a jpg at level 12. You just add file size.  10 is as high as currently needed.

Go try the RP again and this time set it to Average WB.

"If you look at just the area to the left, it doesn't look so blue."

 

The WB is off in your pic too.  Here is the corrected copy.
