Like the other commenters, I think that the sunlight on the grass may be too bright. I don’t think the shadows are too dark, though. In general, besides the whites being too white, this is a nice image and I like your crop and composition. Good eye!

I think Fuji does a great job on colors even the older cameras. But you’d be surprised how much flexibility you can get out a jpeg.

As for the shadows being too dark, I think you’re just asking for too much dynamic range here. The shadows are super dark and the sunlight is super bright. I like the photo as-is but just like @DickinsonSA mentioned, the area in the sun is a bit too hot. If it were me I’d lean into the dark shadows look to get that sunlight exposed properly and let all those beautiful Fuji colors shine.

Not sure if you’re familiar or if the camera you’re using has the option of different metering modes but that may help you get the shadows exposed how you’re wanting. On my A7iii for instance if I want a shot like this I’d use a full screen average metering but if I want more detail in the shadows I’d use multi metering where it will blow the highlights a bit more to get more shadow detail. All of this is kinda assuming you’re lazy like me and shoot in shutter or aperture priority rather than fully manual.

I also really like how the light rays are glowing. Was it super humid or did you use a mist filter? Or is that just how it came out?

Not really sure if you’re have had any more ‘control’ over colours with any other camera - why do you think that’s an issue?

What I really like is the angle you’ve taken it from and the softness that’s coming from the trees in the centre - that haziness for want of a better word.

It’s a very pleasing photograph, my only critique might be that the area of sunlight seems slightly blown out - so I might have been inclined to under expose it by say a third of a stop - of course that wouldn’t help you with your desire not to have the shadows look like - erm, shadows?

Good photo, enjoyed looking at it, thanks for sharing, keep it up, shoot raw.

Edit - missed the fact it can’t shoot raw

This is a pretty photo. The light streaming through the trees, and the mix of flora and architecture is lovely. I wonder how it would feel if you cropped the bottom up so the forced of the wall met the corner of the photo?
