<p>Krista,<br /> I found this book "Understanding Flash Photography How to Shoot Great Photographs Using Electronic Flash" <a href="https://www.amazon.com/Understanding-Flash-Photography-Photographs-Electronic/dp/0817439560">https://www.amazon.com/Understanding-Flash-Photography-Photographs-Electronic/dp/0817439560</a> by Bryan Peterson to be very helpful to understand how to use flash. His book "Understanding Exposure" was also helpful. One drawback for you would be that he uses Nikon equipment. I found his explanation of how shutter speed and aperture affect ambient and flash to be useful regardless of equipment manufacturer.<br /> Hope that helps, <br /> Ray</p> <p> </p>

<p>Thanks to each of you for your replies, in response I have decided on the following courses of action:</p> <p>Shun - I am going to wait to send in the camera for possible repair until I have taken the following actions. <br> <br> Andrew & Simon - I will note how I am holding the body when pressing the playback button to determine if my hand is accidentally pressing another button. <br> <br> Kari - The images I am looking at are the ones that I had just taken. In many instances I was looking at that image and after the view timed out I pressed the playback button and it did not bring the image back up to view.<br> <br> Barry - I will wait a little longer and try it again to see if that helps in those instances. I will also call Nikon to see if they have any suggestions.<br> <br> Thanks again to each of you for taking the time to help me out!<br> <br> Best Regards, Ray<br> </p>

<p>I have been experiencing an intermittent issue with the playback button on my D4. From time-to-time after viewing an image on the LCD after the viewing function times out and the LCD goes black when I press the playback button to view that image again I get no response. I press the button several times to no avail. Any thoughts on what might be causing this?<br> Thanks in advance!<br> Ray</p>
