P: Curve adjustment graph dialog size is tiny. Please make it bigger.

My prediction came true!!! At the time, it was totally a joke and i honestly believed we would have the ability much sooner than that. 2025 seemed so far away at the time and surely, Adobe would see the light before then...

Aside from that, it blows my mind that I went through a 30 year retouching career, using Curves on 10's of thousands of images, with seeing almost ZERO improvements to this basic tool. There's so much that Adobe could have implemented to make this tool more powerful and useful, but it's been completely neglected for DECADES, and is a shining example of how little Adobe cares about those of us who use Ps every day of our lives to put a roof over our heads. 

It's 2025 and the problem still persists. Holy grail!

It will take many more years of experimentation, testing, correction, testing again, and perhaps, someday, we will have the ability to change the scale of the dialog window (not the adjustment layer palette, but the separate "curves" window)

Dear ladies and gentlemen,

The impossible was made possible. The gods listened to our pleas, and let it be known in all the Photoshop communities: 

The Curve adjustment dialog is now...

*sniffle*

Now...

*Sigh*

SCALABLE. Yes, you read that right. It finally happened. It only took 9 years and 4 months for this to be implemented. Let there be rejoicing. Let there be feasting. Ring the bells! Rejoice! Rejoice! Hail Photoshop!

Next, we hope and pray the Photoshop deities for a scalable levels dialog.

This request can now be closed.

I don’t know. I use photoshop as a kind of transport node between rpp (raw photo processor) program to develop photos and 3dlut creator application, where the calculations are made with floating point as in rpp application. All the finishing to the commercial appearance is 3dlut creator. Adobe photoshop acts as some collector - crop, layers. Sometimes generative filling. True, with the last moment I’m thinking about going to flux. There is no censorship and prospects beyond.
Photoshop is doing its job, as well as adobe premiere. It’s a shame. I’ve been working in these programs since '98, I think. Back in the days of '98. Before photoshop was fractal design painter under win95, but not for long.
I would not say that I am comfortable working in several programs, to process one picture, but other aesthetically good options of processing so for me. Photoshop for its time was a harvester. The year before 2010.

@marvinaustin  That's not really the point, is it though? Usability and user experience are.

Sellcome in todays world. Things changed ages who. Photoshop is also used for Webdesign and painting and even if so, the curves windows adjustiert Windows on a 4K screen is 4x4 cm in Size. That's absolut unusable Even for Photo editing 🤦🏻

What is the point of increasing the grid size if the program can only perform integer calculations?

The program is originally designed to output data for printing, where the dynamic range of tones is much smaller than on displays. The light on Photoshop has not shrunk. There is 3dlut creator, darktable and others where calculations are made with a floating point. In such programs, it makes sense to increase the size of the instrument curves.

Wowsers! My feature request is approaching the 8 year mark!

Perhaps a screenshot of PhotoLine might serve as inspiration. Compare Photoshop's tiny Curves editor with PhotoLine's infinitely scalable Curves editor:

...and why is it still not possible to work with LAB or HSV in the curve editor while in RGB image mode? Sigh...
