Can you make the GOES-R SUVI brighter like it is in JHelioviewer?

Hi, is it possible to add a setting or make the projection brighter for the GOES-R SUVI? Because from the JHelioviewer program, there is a setting that lowers the brightness and increases it so that the prominence is visible.

Thanks

I think something like this can be done. The way Helioviewer render's images doesn't support adjusting the "levels" like JHelioviewer (I think that's the slider you're talking about). But it can adjust the brightness and contrast of the image, which gives a similar effect.

Normal SUVI 94 image:

Adjusted Image using CSS contrast + brightness filters:

We could potentially add some sliders for the CSS filter options and let users play around with them.

@wafels thoughts?

It's a good idea, but any changes that are made to how the images are shown in the client will also have to be reproduced on the back-end.

What other CSS could we use? Are there sharpening tools that we can use on the front-end that are reproducible on the back-end?

ah it would have to be reproduced on the back end in order for screenshots/movies to work.

These are the available options for modifying how images are shown https://developer.mozilla.org/en-US/docs/Web/CSS/filter

I don't of anything for sharpness.

Thanks for the interest on this. I understand (as far i can), but if there is any ''solution'' to this, make it especialy for SUVI 304, because, there, it is the more visible solar activity (promenence etc).

And i would like to thanks to whoever (or the team) added the Jheliovierer button in HV. It's realy helpfull, because, the selected area on HV, in JHV, it shows the whole Sun in that specific momment.
