P: Make curves bigger

Thanks, I missed that in the release notes:

And the histogram has better contrast.  Better late than never!

LR 7.2:


LR 7.5:

The curves box is bigger in Lr 7.5

A larger curves panel like in photoshop would be ideal for fine edits and should be a quick fix 

I think Curves could be enlarged both within the panel, and enlarge proportionally to fill the panel if we enlarge the panel, too. I agree the interface is too small. I think they developed it for parametric curves, then threw in point curves without consideration for the need to be able to easily place and manipulate the anchors and the curve right inside that little space.

Make the Curves frame fill its panel fully (see screenshot attached). As it stands now it is too small and has reduced precision in a small laptop screen.

One trick no one has mentioned here is to hold down the SHIFT key, which restricts control point movement to the Y axis. This useful if you want to enter specific control point values such as 22.0%/18.0%. Drag the control point to set the X axis value first and then hold down the Shift key to set the Y axis control point. The Shift key can be used in combination with the ALT/Opt key.

It's not comfortable to use such small curves. You need to hold down the [Alt/Opt] key to reduce curve movement to 1/10th strength.
But it can be more comfortable to use big "Tone Curve" panel.

Another vote for Larger Curves panel.
Make it identical to the significantly larger panel in Camera Raw.
Also, let the user adjust the points with numerical values like you can also do in Camera Raw

I cannot believe this hasn't gone into LR development roadmap yet. Curves control area is way too small to really unleash the power of this feature that resides in precise and small changes, not big curves deviation which leads you to undesired extreme editing techniques.

In the Lightroom Tone Curve panel, the graphic seems unnecessarily narrow considering the potential width of the panels themselves. From what I can tell, the graphic is limited to a square shape of constant width/height. In making restoration edits to scanned slides and film images, I rely HEAVILY on the tone curve adjustments to correct the images for fading, incorrect filter use during capture, etc. Unless these corrections are made using tone curves, white balance is not effective in restoring the colors of the original capture to life-like condition. I consider the channel-specific tone curve adjustment to be one of the most valuable tools in Lightroom for image restoration work.

As currently implemented, however, using the tone curve together with the histogram is less than fully effective. Since the histogram and tone curve graphic are of different widths, one must extrapolate the x-axis location on the histogram where the image needs correction to a different x-axis location on the tone curve. This situation could be easily remedied by making the width of the tone curve graphic adjust to the width of the overall panel (as the histogram already does on-the-fly), so that the tone curve graphic is always the same width as the histogram. Then, the point on the tone curve line is easily selected since it lines up immediately below the point on the histogram needing adjustment. This would require the targeted adjustment tool icon to be moved out of the way, but there seems to be sufficient room below the tone curve box, next to the "Channel: " label to relocate it. Unless for some reason the tone curve graphic must be square, there should be no need to increase the height of the tone curve graphic, avoiding making the tone curve panel take up more space.

I admit, this is not a big problem, but the solution is both simple and elegant, and would be an incremental improvement to Lightroom for the work I do.

Thanks for all you do!
