The Edit/color features in Illustrator would be great if they had more capabilities as in Photoshop. I often need to take my Illustrator images into Photoshop to edit the colors. Photoshop is easier and has more options for color balancing and saturation. And it is easier in Photoshop to match colors from one image to another.

Please add a Brightness/Contrast tool.

Sometimes an illustration just needs more contrast. That is hard to achieve with the 'Edit colors' tool, which is mostly about hue and saturation.

It would be very helpful to have basic image editing effects; such as exposure, white balance, contrast, etc.; in Illustrator. I know it's not an image editing software, but the ability to adjust the exposure of an image that's slightly under exposed for example without having to edit it in Ps would be very helpful. Programs like InDesign and Figma already feature this.

Mark, do you know that Phantasm can apply these adjustments without an effect, directly changing colors? Object > Filter > Phantasm?

It would be great if Illustrator had at least basic photo editing features and there won't be need to switch to Photoshop everytime. For example, bring the adjustment layers in from Photoshop to Illustrator. Also, would be nice having some more advanced Mask features.

Yep. Like Phantasm only without a meddlesome effect. And a bit like the Recolour Artwork tool, only usable (ie. like Phantasm).

Illustrator has a very complex recolor tool with many possibilities. But it lacks the major component of visual adjustment: contrast.
In many tutorials they try to overcome this by increasing saturation and brightness. But that just heightens the color intensity and doesn't come near what contrast is: increasing the difference between light and dark.
It should be part of an illustration app for professionals. I am puzzled as to why Adobe can't work this out. The company Astute did it years ago. But you have to pay a yearly 120 dollars just to get this effect.
I would say: get your best man to fix this. Customers will be delighted once they will start using contrast afjustment in their artwork.

Please add the ability to adjust an image's color from within Illustrator. Nothing crazy, just HSV adjustments, Curves & Levels, etc...

Ditto!!

Very useful feature

Change brightness and contrast easily. One easily accessed option. What on Earth is saturation and why does it tell me that my coloured image has no colour?

We end up forced to use Astute's plugin. Their owner uses some seriously shading billing practices.

I don't understand how this is not basic functionality of Illustrator.

It would be great to have the ability to manipulate colors across multiple vectors by HSB. There is a plugin capable of handling this by Astute graphics, but their pricing practices are criminal in nature. They are currently trying to double charge me for their product and I'd like to just get away from that company all together.

Gravit Designer has this feature. It's so awesome!! I would love to see this in AI

Bring all of the color adjustments that are found in the Edit Colors submenu of the Edit menu to Recolor. So we can go to one place and make all our color adjustments.

Color adjusment like Photoshop: Hue/saturation and Brightness/contrast in one window

The question is why this is not yet on the FX Appearance list??? Adobe this is basic for image in Illustrator. E.g. For textures in masks etc.

1) Not necessary to incorporate the full photoshop adjustment suite to illustrator, but basic tools like contrast/brightness/nonlinear contrast adjustment would be INCREDIBLY useful.
2) Photoshop is not great for working with large arrays of images (illustrator is better for this) BUT its frustrating that images can't be adjusted side by side once imported into illustrator.

Currently I have to use Astute Graphics plugin for this. It is awesome! Please copy how they do it. Please buy them out and add everything the do to AI
