Pure Joy
Lens: SMC DA* 16-50mm Camera: Pentax K-3 Photo Location: Portland, OR ISO: 100 Shutter Speed: 1/1500s Aperture: F4 
Posted By: ThomSirveaux, 10-26-2018, 08:37 AM

On a recent trip to visit family in Oregon, I was able to capture this moment of pure joy from my daughter

Should I have bumped the aperture up a little higher?

Hi,

I am not sure about the aperture, but to me, this shot is super-awesome as is :-)

Regards,

Suhail

The aperture probably isn't the main point about this photo! A great fun filled image...

BTW what did you mean by your question about aperture ...."higher" ?

I have no idea what I should have said, but since it was F4, I was thinking maybe an f8 would have been a little sharper?

F8 is a smaller aperture then F4, and yes, it probably would have given a sharper subject. The shutter speed has a major impact in photos like this, and your one here is "fast" (ie a very short time, 1/1500th sec), which helps to freeze the small subject movements. Changing to F8 is two stops , so the shutter speed would change to about 1/350th sec, still enough to stop the motion .... So in this situation then F8 should have worked well.

At a shutter speed of 1/1500, focus is the main determinant of subject sharpness. If you had gone to f/8, a shutter speed of 1/350 would still be plenty fast, but the background would be much sharper ..... for this kind of photo, I'm not sure why you would want that, since the background would take some attention away from the subject.

Yes, I suppose if you wanted to retain F4 (and your lens performs well enough at that aperture) then the other option is to increase ISO in order to keep that 1/1500th exposure time..... So here you would end up with ISO400.

This type of photo is a good candidate for TAv mode, as you would pre-set F4 and 1/1500th and let the camera choose the ISO. That way you retain control over the two most critical elements.

This is a great example of an image where the minor technical flaws seen by the photographer are well overtaken by the joy experienced by its viewers. It's a keeper, for sure!
