JayT those look really good. You seem to have got a lot more feather detail than I managed. Did you take these with the 5d or 7d?

the 7d can be a pain in the a in \$hitty light when being use to a 5dii

Unfortunately in northern Scotland that is the light we often get even in late June in the afternoon, although sunset is after 10:30pm if you can see it through the clouds / rain! I haven't used a full frmae like the 5Dii/iii, although I would like one.

I find the 7d has problems with yellow feathers on birds.It blows the yellows and if you lower it in post they don,t come back to good . Anybody else agree or is it me alone ?

I don't know whether this is true or not. From the histograms it doesn't look to me that the yellows have blown. It may be my PP.

It may not be blown but what mean is the 7d has trouble showing detail on yellow feathers to where they seem to be blown. Like your yellow hammer in the pine tree. His head lost detail and the yellow warbler I just posted is the same way and I pp it to look the best I could and it was not blown on the raw file either. Just seems the 7d and I don't resolve yellow feathers to good

Gabe, maybe you or someone can post a yellow bird up close like my cowbird and show me some detail

Here's the best I could find from the last few weeks and had to play with it to get it to look like this. Top of his head has no detail and the rest of him has brown in the yellow which saved the detail

2 bluetits with quite a lot of yellow in them. In the 2nd picture the area at the top of the breast which is best lit does seem to lose detail.

Exactly, Its hard to get right and gabe your look great also to but some of the yellow in yours also has lost detail but not much. just a little by the front of his neck

Some loss of detail in my photos is sometimes due to Photoshop's Reduce Noise effect.
It has a threshold; detail that is under (or over?) that threshold will be smeared because it is thought to be "noise" by the program. So probably that area on the neck had some minute detail that did not make the minimum criteria to be considered valid detail and hence did not survive the Reduce Noise effect.

It is possible that there isn't much detail there, feather may be so tightly packed that it just comes across as one uniform area.

Why not using the "luminance" buttons on LR?
Drop a bit the yellow one and details should come

good tip, I do that too occasionally for reds.

Post 12 of the linked thread says that it was a 7D that took those photos too, so maybe you have a point
