P: Add Desktop Color Calibration tool to Lightroom Mobile App

Please introduce the calibration sliders to the iPad version of Lightroom. I need to edit photos on the go and this tool is essential in my workflow. It will save me having to lug a laptop with me for travel shoots. 

Can you add the Color Calibration feature, like in Lightroom Desktop, to Lightroom Mobile?

I seriously can't see any other reason that a deliberate sabotage of the product by the decisive person (product manager?).

It's abysmal.

I just went ahead and "added" this feature myself by making presets that cover the ranges and increments of the calibration sliders I tend to adjust when using the versions of Lightroom that offer the sliders. As others point out, the underlying capability to respect calibration slider adjustments is there in LR Mobile's rendering engine; the sliders just aren't offered in the mobile app UI for reasons that Adobe has never shared.

So I don't have a lick of software development training or experience, but a few minutes of exploration and tinkering taught me that presets are just stored as text XMP files in my Mac's "Application Support" library folder--meaning I could just make one preset XMP file, duplicate it, and then change the tag & increment parameters on my Mac's text-edit app; lather-rinse-repeat over the ranges I want to adjust, sync my new presets to mobile, and 45 mintues later I effectively have the calibration panel in LR mobile, covered by a loooong list of presets. Finally. It's kludgy but it's there and it works. I just scroll the presets rather than slide a slider.

Which begs the question: if I, joe-nobody-who-is-not-a-software-developer-by-any-stretch-of-imagination can jam these missing sliders back into existence in about 45 minutes of tinkering . . . why can't a pro at Adobe just bang it out officially in an update? It's not like it'd take an Adobe pro any longer than it took me. I had to figure a bunch of things out along the way; none of you do.

Just super weird that these sliders are still missing. Super, super weird.

Yea its time!!!

Editing on IPads is so nice but held back by that one missing Tool 
it feels like they dont want it to work. 

Even though editing with pencils on a tochscreen is the best possible way to do it

What wrongly_Neo just said is what I think frustrates me the most: the core engine for rendering is clearly the SAME.

Which means the time to develop the feature is only adding sliders to the UI.

And honestly, this is the case with almost all iPad requests that are in this forum.

Very very simple features, which are being ignored for literraly years.

This was already requested 5 (!) years ago.

I start to believe someone decisive at product management team of Lightroom is just sabotaging the product, because such a lack of features (which are easily implementable literally in minutes, as was said, it's just about adding the sliders, as engine is already supporting all features at all versions) is incomprehensible.

I recently got myself an iPad Pro and tried editing some of my Photos on there using Lightrom (synced over from Lightroom Classic). Turns out, the workflow is actually pretty nice--if there just wouldn't be the one thing that kills it. It's the fact that the set of develop settings that you can modify seems to differ from each version of Lightroom to the next.

While Lightroom on the iPad is apparently able to correctly render all my adjustments made in Lightroom Classic, some just cannot be modified. One example is the camera calibration adjustment. The panel just seems to be missing. What makes it even more strange is the fact that I can apply a preset that includes camera calibration adjustments, and they will be correctly applied, but I cannot manually adjust them. The sliders are just not there.

Unfortunately, this affects some of my favourite tools, including camera calibration, the refine saturation slider for the curves, people AI masks, point colour, and curves in local adjustments.

I checked some of the other versions of Lightroom, namely the Lightroom CC desktop app, and the Lightroom CC browser version, and they all seem to differ from each other in one way or another. For example, if we stick with camera calibration, this option can be made available in the Desktop CC app by clicking the ellipsis and selecting "Show camera calibration". In the browser version, however, even though it looks practically identical, this option is not there (and I don't think there are any technical reasons preventing this).

I am aware that Lightroom Classic and Lightroom CC take some different approaches when it comes to organizing photos, and that is ok. However, I think the develop settings should (wherever technically possible) be identical between the different versions that Lightroom offers, at least on desktop and tablet operating systems. Otherwise the whole Adobe Cloud workflow, while being a nice idea, is nipped in the bud.

I also dearly miss this setting on the iPad. 

I generally don't understand why there are different develop settings in different versions of Lightroom. All the settings of Lightroom Classic should be in all the other apps. Otherwise this counteracts the idea of the Adobe cloud. When editing on the iPad, why should I suddenly not need a setting I use in Lr Classic?

Please bring feature parity on mobile and iPad.

Missing features: masks amount slider and calibration.

Adding mask amount slider is probably about 3 minutes of work, yet for many months it's still not added.

How can you expect users to use iPad version together with desktop one in their work when this features are just missing?
