Is there a way to turn off the D+ Highlight tone priority setting after the photo is taken?

[mmphoto]

Hello,

I'm trying to use the multiple exposure settings to take a time lapse of a tree by using the overlay effect. Unfortunately, the first photo I took in the series had the D+ HTR selected. When this is selected you can't use the multiple exposure settings.

Is there a way to turn the D+ setting of the RAW file off in camera or iwth my computer?

Thank you!

Hi Danny,

I'm using a 5d Mark iii. This must be a pretty rare issue. I always have D+ HTP set just in case I shoot any video.

When I go to "Select image for multi expo" it shows me the compatible images, but when I select an image that was shot with the D+ setting ON it says that the image isn't compatible.

So I was wondering if there is any way to turn off the D+ setting after the raw photo has been shot with that setting ON.

Thanks!

As far as I know you can't change the HTP setting after the shot was taken in Canon software so it treats it differently.

There are however several software programs (i.e. Photoshop, Paintshop Pro, and perhaps PS Elements), that would allow you to layer the photos taken with HTP on for a multi-exposure effects.

Hey TTMartin,

The thing is i'm trying to take a photo in the exact same place. A tree in different stages of life. So I was going to use the multiple exposure setting just as an overlay device so I could get in the same position every month.

Sorry can't help you there.

I believe HTP affects the file, rather than being a data tag, so it can't be undone.

No there is not. HTP is just another word for underexposure.  It allows more room in the highlights at the expense of increased noise.  It is the way a RAW file is made and saved.

Some Canon cameras have both Highlight Tone Priority and Auto Lighting Optimizer settings.  
Auto Lighting Optimizer (ALO) analyzes contrast. It modifies both shadows and highlights by adjusting the tone curve in high contrast conditions.  It is not reversible afterwards either.

There are only a few certain things a camera sensor can do.  Everything is a modification of these.  Remember there is no free lunch.  You give to get.

Thanks ebiggs1. Hopefully this is something canon wil address in future models.

If you shoot RAW, ALO can be turned on or off with DPP.
