About the Image(s)

While walking I spotted this Bald Eagle flying across the Delaware River. My Sony Rx10iv was set at F8 ISO 100 1/60sec. I have been experimenting with using F8 instead of my usual F4. Somehow my photos seem to come out with more noise though? I played with processing a bit with Topaz trying to get it sharper but .. maybe too much? I was quite far away from the Bald Eagle . Any suggestions on how to improve it would be apppreciated.

A most interesting image. The detail in the wings is great, the reflection in the water is excellent and the composition is well done (although I'd prefer a touch more space above the eagle). It looks like you used some sort of filter to get the look. While interesting, I'd love to see the original. This looks like an image that would be impressive without any artistry filter.
I'm a touch confused by your comment re noise. Generally, a higher ISO setting (say going from 100 to 2,500) will make the noise much more noticeable. I would not expect to see any noticeable noise at f/8 (with settings of ISO 100 and 1/60 sec) vs. using an aperture of f/4 (and keeping the ISO at 100 and adjusting your shutter speed to a faster setting to compensate for the wider aperture). BTW, many people (including myself) think very highly of the Topaz Denoise app, which does a wonderful job of fixing noise issues.   Posted: 08/04/2022 20:16:57

This is one of the originals- nothing done. Suggestions appreciated . I want it to look natural - not filtered.   Posted: 08/05/2022 04:59:36

Hi Kathleen, it's really hard to work with the file you uploaded because it is so small. However, I suspect that one issue is how far the eagle actually is from you. You had to crop a lot to get the eagle to be a decent size in the image and this can cause pixelation and also bring out the noise.
I think your camera has a 24-600mm zoom lens and if I'm correct then zooming in closer will help with clarity and reduce the need for cropping to get the eagle to be a decent size in the image. If you are already zoomed to 600mm then I'd suggest that the eagle was just too far away to get a good shot.
Given the original image, I think you did a very nice job on the image.
Not sure if this helps.   Posted: 08/05/2022 09:29:05

Your comment about using f8 instead of f4 is interesting. For a picture like this, where my intent was to freeze the motion AND separate the eagle from the background I would 1. use a long lens (fill the frame with the bird) 2. likely choose f5.6 or f8 f stop (separate the bird from background, but have some room to accommodate sharpness for the whole bird) 3. set ISO to 400 (maybe even higher because I really want to freeze the bird (shutter speed) so the details are captured) and 4. make sure my shutter speed in that light was 1000 or higher (freeze every detail).

All this is to say you did something right because the capture and the detail is amazing. I do think if a bit over-sharpened...see the fringing on the reflection of the wings.   Posted: 08/05/2022 10:39:44

Amazing shot! Seems quite sharp to me. I would not change a thing.   Posted: 08/08/2022 17:06:22
