Being an old "Film" person, will somebody please tell me why when the background is white there are less pixels in the picture and so the size is always smaller. Whenever I take such pics they are always too small to be accepted by sales agencies. One other thing, this macro lens is max aperture f2.8, why does it come up as f3.5? Thanks in advance.

Can't answer the questions above Frank sorry
However a smashing macro, excellent detail and the diagonal composition just finishes it off.
Excellent work Sir, well done.

Very nice image like it a lot and the white background works well
You often see a large reduction in file size if the image is in JPG which is a lossy comprehension process, if there are large areas of white (or any colour); the algorithm will discard all the white information and produce a very small file.
As to your lens I haven't a clue

So as I started in RAW when there is a large mass of white I need to change to perhaps .tif to keep a large file the problem is that Alamy only accept .jpg files. Thanks anyway for the answer.

What setting do you use when exporting to JPG? if you are just using the default setting which can be around 75%; try setting the compression ratio to 100%. it could make a difference

I emailed Alamy and they said that despite the image being 1.1mb it was Ok because: If you go to "Image" - "resize" - "Image size the block then shows Pixel dimensions 34.7mb. Very strange and no explanation but there you have it. Files it would appear, have a hidden size as well as the one which is easy to see, Now I am even more confused.
Steve I always export in JPG at 100% when using files for sale and also set the PS output to 100% as well. Thanks anyway.
