Excellent work as always Gabe

thank you.

My lens is getting a workout this week. Latest shots from yesterday. One of my "nemesis" birds finally caught
Wood ducks. with 7D and 2x tc. Cropped from 18mp to about 6-7mp then processed and resized.

Gabe beyond you photographic skills, which are awesome. You have a real knowledge of the processing and resizing of the work. Do you have any links you can share so a dumbass like me can understand?

Example:

How do you know what size it was cropped too? Resized for what?

Like I said...you don't need to take your time answering me, but if you have any links, I'd love to have them.

Thanks
Paul

I have changed my C70-200II for 120-300OS. I made a little test. 2 cars driving to me. First 20 shots was bed for me. = 50% accuracy;/ Second try was much better, only 2 from 16 missed the target.

On Monday i have first match and then i will share my opinion with you

Well, this is just a rough estimate but after cropping the original for composition I ended up with an image size of about 2700-2900 pixels in the longer dimension which in a 3:2 aspect ration calculates to about 6-7 mp (I haven't done any true calculations).

Nice shots, I am subscribed to this thread just to see Gabe's work.

Yup. Gabe has been posting some more amazing photos. I jush wish I had some birds
around to take photos of. Let alone half of Gabe's skills.

Can only join those being inspired by Gabes photos. Its so nice to watch.
Gabe could you enter the settings that you use?.. for instance 1/400 f/10.0, ISO 400, tripod
Its just a request, not a demand

You need to learn how to use the information that is readily available to you.

To see the EXIF metadata, simply click on the image that you are interested in and this will take you to the image where it is stored: on Flickr. Once on the appropriate Flickr page, look at the left above the image and notice the menu options, one of which is "Actions". Simply click on the drop down and select "View EXIF" and there is all of your info except the Q about the tripod.

Can anyone advise what uv filter (or any other) they are using on this lens without any effects on IQ. My concern is only front element protection. I bought a Sigma 105mm UV DG filter and for the price, its build seemed like a cheap ebay filter. Hard to describe but you know how the cheap filters seem hollow and the glass isn't really snug fit within the rim of the filter. Not what a CDN $200+ filter should feel like at all!!!!

I'd use an "air filter" and the lens hood.

You mean just blow off dust particles with the air blower?
