I have often struggled with red objects in my 5d3. I wrote last year about it but did not get any replies. Yesterday while trying out my new 85 1.2 ii, I saw the same issue.
Red flowers come out in an over saturated red haze. The other colors seem saturated just fine, but the reds are over powered so much that the flowers lose detail.
I can reduced saturation in LR, but then the whole image looks washed out... the issue is only with reds.
If I reduce just red (Red channel only) , then it lacks punch, although I get back details in the flower...
Has anyone else observed this?
Looks like your auto white balance is thrown off by the amount of 'green' in the photo (greens look too blue). Try a WB setting of 'daylight' or 'cloudy'. I find this gives the best overall results if shooting in a 'green' environment.
My one experience with a lens being completely destroyed by a drop was entirely the fault of using plastic for the filter threads. Had they used stainless steel or aluminum, it would have bent a little, and the filter would have shattered, and that's it. Instead, the filter threads shattered, and the lens filter (whose threads were made of metal as they should be) dug into the front glass. The cost of replacing the front glass was more than the lens was worth, so I considered it a complete loss and moved on, but I'm very wary of plastic parts on lenses these days as a result.
At the very least, filter threads on a lens should always be made of metal. Anything else is a hack.
I'm fiddling with it now. Is microcontrast just DXO's term for the clarity slider from ACR? Seems very similar. It's a 'more detail at the cost of an HDR look' sort of tradeoff to me.Yes, that's a good way to put it. I generally go light with that one, maybe +5 to +10 if needed. Also, if you expose to the right (or have shots with blown out highlights) the "Highlight Recovery - Strong" in the Exposure dropdown is pretty amazing.
DxO might be a good choice for you as it's really designed for two types of people - users like yourself who prefer to have the tool do most of the work, and users like me who are
insanelyslightly obsessive about processing 100% of their photos from RAW. The basic processing works extremely well and the general sliders are easy to use to tweak your photos a bit, but there's lots more if you get into it.
On the other hand, the interface isn't the most intuitive and you have to export everything to file (or other apps) and that can be a little hard to get used to compared to other apps. I'd recommend downloading the free trial to see if it's for you. These two tutorials should get you started:
It's typically a love/hate thing with DxO, but try to be patient at first, it really is a great program once you get the hang of it.
Yes, DxO does sharpening as well, and it's probably the best and coolest correction they do as part of the profile because it's done per the lens's "softness" profile. That means that it sharpens very little in the center and more and more towards the edges. It's also done using some method that produces little-to-no artifacts, at least at the default setting. For me, it's great because the default settings work very well in 90% of the photos I take and that saves me from the time needed to sharpen like I do with ACR.

...and yes, DxO should pay me for being such a big fan/supporter...but they don't!
P.S. the profile from DxO seems to work exceptionally well. I applied it to my test shots and the 16-35 f/4 IS comes out quite a bit sharper than the corrected 24-70 f/2.8 II photos! That seems crazy but is what I'm seeing. I'll have to play with it some more this weekend and do some more side-by-side photos, assuming the weather cooperates.
Oh I hate this. I sold the 16-35 f2.8L II, got the Zeiss 21/2.8 and Zeiss 15/2.8, in addition to the 17 TS-E. And I was so happy for several weeks.
Reading the test of this new 16-35 throws everything into the boiler again ...
