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

mmphoto — Sat, 16 Jan 2016 18:41:07 GMT

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.

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

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.

You must remember I am not a DPP fan or a real user of it. It is my understanding that a jpeg with ALO is a permanent setting. But I also understand it can be applied afterwards in post with DPP. It is my understanding you can turn it on or off in a RAW file too. But it can not be removed from the RAW data file using DPP. Most settings for a RAW file are added by the post editor since most do not affect it. But the data tag file remains as is.

I preferring to do it in LIghtroom.

ALO is simply a flag in the RAW file, it doens't impact the RAW data in anyway.

When you use Lightroom having ALO on or off when you take the photo will have no impact on the processing of your RAW file.

As for JPGs of course all camera settings are baked into the JPG file including things like the Black and White Picture Style as well as ALO.

"When you use Lightroom having ALO on or off when you take the photo will have no impact on the processing of your RAW file."

Yes, I think we agree or are saying nearly the same thing. "It is my understanding you can turn it on or off in a RAW file too. But it can not be removed from the RAW data file using DPP." It still resides in the RAW tag and can't be removed.

Please note I am not a DPP user, so whatever its feature set is is not my forte. If you are using LR there isn't a ALO switch. Unless I have missed it somehow. The way LR converts a RAW file will not be the same as the way other convertors, such as Canon's DPP or even the in-camera processing, will.

LR applies its settings, rather than the in camera settings. I believe only Canon's DPP can ALO in post. If ALO was selected in the camera, DPP will apply it by default, but you can also select DPP to render the RAW file with ALO switched off. However it remains in the RAW files data tag.

I think that's correct, if what you're trying to say is that the Exif metadata will continue to indicate that the picture was taken with ALO, even if you turned it off in post-processing. (Or if you changed the ALO setting without turning it off; there are two "on" levels available in DPP.)

But otherwise, I don't think the statement makes much sense. The ALO algorithm does what it does, either in-camera or in post, but the effect applies only to the resulting JPEG. There isn't any "data" to preserve in the RAW file, just a bit or two to indicate the level of ALO that was originally called for.
