Cheers!


My standard editing with DT. BTW, I remember from the days of film that red flowers can be very difficult to capture as the human eye perceives the color. There are colors in flowers that the human eye can not detect, but film and probably digital cameras can detect.

The hue rotation in rgb CB might also be useful for these sorts of images to try to nudge them to the right look …

What is this? Is it in RawTherapee?

No DT but you can use the curves and do hue vs hue or play with saturation at the specific hue and likely tweak the rose to whatever you want from yellow orange red to pink… :slight_smile:

EDIT : I even feel like there is an example of dealing with a rose in the rawpedia literature… I will try to dig it up…

EDIT2…

Local adjustments… tweak away… wasnt a rose but red flower none the less

EDIT3
Are you trying the different tone curve options…you will get quite a different starting point…this is something to check out… saturation and weighted for example not the same as the default

This is art but same is found in RT…

See you can go crazy with this really easily or be very measured and make a small tweak

My version…

I was hoping that somebody who is more skilled than I
would have brought up a discussion about out-of-gamut,
color profile, and other nasty things.

What would be the best way to check/measure/tell whether
a certain image falls within the boundaries of a certain profile,
like sRGB? And what to do if it does not?

At the bottom of this page there is another red rose
to play with: Examples of various wide-gamut images

Have fun!

Yes, Red is difficult to process!
My meager try using Fuji X Provia LUT

edit: just noticed strong banding in the blurred blossom :frowning:
edit2: this comes from the film simulation

Trying Fuji Superia 100 from HaldCLUT package. This is much better, but less pinkish

There is a button on the bottom of RawTherapee that does just that

Yes, and we have a similar one in darktable as well,
but I thought of a plot into something like this:

Hmmm, I tried, well may be not well enough. The use of a profile made for a different camera is a bit of a hack, but not a horrible one as my rendition shows.

A reminder that you should post HD rez images and the sidecar. We don’t need 30MB jpgs. We store this information indefinitely.

Another take, focused on color and details.

I downloaded the raw and opened it with the Neutral profile in RawTherapee. In the petals lots of greens are zero, indicating gamut-clipping. Reducing Saturation fixed that.
Ted.

Definitely not true to life, but I like the tonality.

I really need to pony up and get a device to calibrate my screen. For sure I just went for a pleasing “red” on my screen knowing for sure it was not “real” but real would require some screen and camera calibration :slight_smile:

But that wouldn’t necessarily have helped with this image. The whole problem is that my camera does a lousy job capturing these reds.

I think your camera is doing okay, but extra attention is required to not crush the reds in getting to rendition colorspace. The numerous submissions here show that…
