It is the lower left and here is a blow-up of the area easy to remove in Photoshop. It must have been in tiny bit of wind on only one of the stacked images when shooting.

I like to learn the names of the birds.

Yes please!  I find it incredibly frustrating seeing lovely photographs of birds but no description or caption.  Sometimes, when I have time, I embark on a search for similar images which are named, just so I can learn the names.  I do know the names of a handful of birds but not the vast majority.  It would be greatly appreciated if a caption with plant or bird name was added to most images also location for landscape images.

I always try to include other relevant data like camera/lens and exposure details so others can see how the photograph was created.  I have in the past been influenced in my choice of gear by images here and elsewhere because the poster was kind enough to add the basic shooting data.

As Eric says ....... "But it soon became clear to me that pursuit of excellence wasn't so much about equipment but more about fieldcraft, local access and being prepared to invest time...more time than I was prepared to invest."

When I got the D3, it rapidly occurred to me that long glass is needed for distant subjects, way beyond my pocket if they were to create good quality images.  I set a notional limit of 300mm, retaining my 300mm f/2.8, giving me an equivalent to 450mm on DX.  I parted with my 400mm f3.5 because it 'broke the rule' and was only slightly longer anyway and heavier.

In general I definitely agree with Eric's comment..."To keep interest we need new topics. The trouble is they seem to be fewer in number these days."

With the advances in technology and user experience we have fewer technical problems, most wrinkles have been eliminated and therefore questions and discussions are fewer.

I am happy if people want to take photos and only participate in only one thread.

I feel the 'theme' threads like the bird photography thread ARE the way forward, that thread has by far the greatest views of any thread we have seen on this forum, I believe all contributions add to the diversity of the content of that thread.

I am constantly striving to widen my experience of photography and learn new stuff.

Wide spectrum photography, night time and focus stacking are all technically challenging and push one's abilities and understanding of photography further.  The  choice of lens is also extremely important with focus stacking.  The choice of lens has a huge influence in the final image.  Focus stacking is one of the most challenging aspects of photography.  I am planning a purpose made bench and a novel mount for that when I have time.

What help do you need?

The process is basically the same as the attach file routine with one additional step - once you have browsed to the file you want to upload and clicked on the upload button, wait for the file to be uploaded. When this is complete you will be shown a paste to post button which inserts the picture in the post text - this means you can add text above and below the image. There is no resizing of the image involved so the quality should be identical to flickr etc.

The attach file routine DOES resize over large images and WILL degrade the image, just as RAW to jpeg loses 3/4 of the pixels the resize will lose pixels depending on the degree of resizing - halving the width & height will lose another 3/4 of the remaining pixels leaving only 6% of the original RAW image.

Attaching the file appears to be faster, but the file is attached AFTER the post button is pressed rather than being included within the post text.

The advantage of using the blue cross is also that the image is included in your gallery and can be reused without needing to upload it again, the URL of the gallery image can also be used on other sites or emailed.

If you have problems with the upload, let me know and I will try and help :crossed

Not thick Graham! Programming thought demands different wiring from an artistic bent.

Back on Topic.

Tried a series of Focus Stacking shots today of a poppy field with my Z7 but I need to see how good they are and if I got what I wanted.
First look indicates I need to practice more.

The Z7 must have all the Auoto Focus Shift Setting like the D850? I must say they work very well on the D850 tried to do a dead fly with the 105mm but it is the wrong lens for that as 1:1 is max: Micro photography is not my interest Africa put me off bugs for good

The Z7 is a mirrorless version of the D850.
It is difficult to tell the difference between images from the two cameras.
