Lightroom: Auto-Exposure in addition to Auto-Tone

Mods, please don't roll this into another thread. I've posted this in the past and it's been lost in noise.

One of the on-going issues with applying develop presets, particularly on import, is when you'd like LR to "ballpark" exposures using Auto tone. The major issue here is that Auto Tone controls all the sliders in the "Basic" develop pane, meaning any control you'd like to have over them is taken away. And, even if you decide to apply Auto Tone on Import and then apply your own, or a third party preset afterwards, if Auto tone still has control over the Basic pane, any of those settings included in your preset are overridden (or negated would be a better word).

I don't know about anyone else, but all of my develop presets, and all those third party presets I have purchased, seek to apply some changes to sliders in the Basic pane. But two sliders rarely touched by the presets are White Balance and Exposure.

If Adobe could add an Auto Exposure option that controls ONLY the Exposure slider, this would fit perfectly with most develop presets without clashing and give us the option of having LR set a ballpark exposure whilst our presets control DR and contrast options (see below). And, let's face it, anyone using a preset that includes an exposure preset, won't be selecting Auto Exposure anyway.

It is very simple for me, I never use an Auto process, I hate to be forced in a corner from where I cannot escape anymore.... This a statement I have regarding all developing softwares.

Thanks Michel. Two points: Firstly, there is no corner into which you are forced. LR is non-destructive. And secondly, nonetheless this is fine for you, so this thread has nothing to offer for you.

You can do this now using two steps. First create a Develop preset that applies only Contrast, Highlights, Shadows, Whites, and Blacks all set to 0.

1) Select ALL image files, set Auto Sync, and  hit Auto Tone.
2) Apply the Develop Preset with Contrast, Highlights, Shadows, Whites, and Blacks all set to 0 and unselect Auto Sync.

You can't do this using an Import preset, but pretty easy to do none the less.

BTW–You can apply specific Auto Tone control settings such as Exposure to individual files by holding down the SHIFT key and double-clicking the Tone control's name. Enjoy!

Please understand, those who feel I'm being unreasonable or grumpy, not everyone runs a photography business (or hobby) where individually honing each shot to perfection is possible. Some of us need to batch process large numbers of shots and get them delivered in order to turn a buck and (it seems to me, at least) one of the major reasons for paying for an application like LR each month is to help streamline our workflows to the max so we can deliver the best shots we can in the most profitable way possible. 

I fully get that, for many, the idea of using Auto Exposure over a batch of images is as appealing as eating worms but, for some of us, have software "ballpark" our images in bulk could make the difference between a viable business model and a job at McDonalds.

I feel I need to point out what I'm suggesting here.

Firstly, this is a minor coding job. LR already has two ways to invoke the Auto Exposure routine (that I'm aware of), 1. as part of Auto Tone and 2. through shift-double clicking on the slider. All I'm asking is for it to be given it's own button.

Secondly, this would totally address a long-standing bug as linked by John above. Gone. Eradicated. Never to return. 

Surely that must qualify as a win/win?

Hi Shane, I absolutely support your request. Auto tone, though nobly intended, is essentially useless for me too.  I shoot wildlife, people, interiors and vehicles. Auto Tone simply does not work for a majority of these subjects. 

A simple Auto Exposure option would save me enormous amount of work, as I too frequently need to import / process many hundreds of images with tight deadlines.  Theoretically, it is possible to set exposure of one image and then use the  Photo > Develop > Match total exposures, but again, it does not work reliably.

Bob - I read Simon Chen's post, but we are talking here of a basic tool that needs to work on the majority of images, and it does not.  - we should not need workarounds.

Going back to Capture One which I worked with for many years, there is an auto levels tool that does exactly what is needed on 90% or more of images #SuggestiontoAdobe

That is a great idea and very useful if Adobe implements it so that the image files are updated real-time instead of as a background operation. I've added my vote. I would also like to see the current Auto Tone bug fixed as well, but that may be a more challenging issue since it requires more processor utilization (i.e. more 'Auto' settings calculations.

On my modest system it takes ~3.0 sec. to apply Auto Tone to a 21 megapixel raw file. Using SHIFT click on Exposure it takes abut 0.25 seconds. With 1,000 image files (1,0000 x .25) it would take ~2.5 minutes. No need to do that as a background operation–Put it into the foreground and show it in the taskbar. If necessary Adobe could even lock the Develop module and Quick Develop panels and show 'Calculating' in the taskbar. This would prevent someone from applying a Develop preset before the Auto Tone operations completed. Just thinking out loud here.......

Real time makes absolute sense. I'm not expecting absolute perfection but if 90% of the images are right, or close-too, then preview to clients is that much quicker and my eyes are saved a little bit of pain

This reply was created from a merged topic originally titled LIGHTROOM Auto Exposure Option for Import Develop Preset.

I can make a preset for every setting in lightroom, but making a batch setting for exposure is something I can't do if all of the photos are slightly different.

Can we have an option that "auto exposes" imported photos before culling while leaving the rest of the work to our import preset?

If there are under exposed images in a set (shooting during bright days for example) it's hard to sort through without first adjusting exposure. Basically the tool would take a look at the histogram and change the exposure weighted towards the emptier part of the histogram (or do nothing if it's close enough). In the case of an underexposed image it would know to go right, overexposed it would go left.

(you might have the code to do this already since there's already an "auto tone", it would basically refine the functionality to just exposure.)

It doesn't need to make every image spot on (subjective etc.), just enough to cull through photos without having to make exposure adjustments to see the image while sorting.

The Auto Tone could be expensive to depending on the workflow. The reason is that Auto Tone is image content aware so it needs to load the raw negative (albeit a lower resolution of the raw file, like the Smart Preview is typically good enough). The Camera Raw cache or DNG fast load data helps, but in other cases it could hit the disk pretty hard if doing it in real time, other than as a background task as Lr does today. The AutoTone in Develop is fast because the raw negative has already been loaded.
