Welcome to the forums, @mirandawaite!
I must say, I really like the posture of the cat. It makes it looks close and affectionate.
After I read your comment, I did some research and found that the “no flash setting” I was using can cause camera shake.
Well, using no flash does not necessary mean camera shake. It just means that if there is not enough light, the camera won’t allow the flash to pop up, and will have to compensate the low light with higher ISO, wider aperture and/or longer exposure (slower shutter speed). Just curious, what is the ”no flash setting” that you are using?
Can you sharpen the eyes with Adobe Lightroom or some other photoshop program?
You can sharpen the eyes to a certain limit, but, unfortunatly, editing software can’t just make up details that are not already there. 🙁 It can help, but it’s better to have already a sharp picture. I don’t have LR, though, but at least it’s the way it works on my editing software.
