Exposure question..

Recommended Posts

to save time, i was wondering if any of you could let me know which of these is the more correct exposure. maybe they are both wrong? i just chopped both out of the center of the image in paint. no pp. i was just trying diff. exposure techniques today but could use advise. both are 5.6 full zoom @300mm iso 100 1st one is 800shutter next is 640.

i needed an image,and this dove happened to be around. thanks for any help.

The second looks a bit better to me. What will help you the most is use your histogram. It is separated into five "zones" with the left being black and the right being white. If you try to expose so that you get your peak slightly to the right of center you will find that you will be in the ballpark of correct exposure. This is just a general description, not a detailed one by any means, to give you an idea of what to look for.

Do a search for reading histograms, there are a number of good tutorials out there. Learn to read the histogram and you will find that exposure is an easy thing to get or adjust to get a well exposed shot. Good luck.

I agree with everything Dan said.

No. 2 is better. Any image that's exposed longer that dosn't blow out your highlights is generally better than a shorter exposure. The shadows will be brighter and hold a lot less digital noise the longer the exposure is. Especially if you're shooting RAW, it's very easy to adjust the image exposure in PP.

MM, number one is sharper, but you framed your question around which was the best for exposure, not sharpness. Because of that difference in sharpness, No. 1 is the more usable image, and at iso100 and that truly fine quality sensor, it's not underexposed enough in the wing shadows for you to worry at all about digital noise. If you'd shot it at iso800, you'd have more noise issues to worry about. Bumping the iso to 200 would have given you an exposure like No. 2, but at 1/800, not the 1/640 that produced this slightly softer image.

it has been said that this lens [70-300 is] is soft at the long end. does #1 look about average for sharpness for 300mm? straight from the camera. i was handholding. you guys have seen soooo many more photos than i,that is why i ask this. may seem like a dumb question,but i have nothing else to compare it to. you know what i mean? thanks.

MM:

All telephoto zooms are inherently a bit soft when shot with a wide open aperture at full extension. It's just the mechanical nature of that particular beast. When stopped down one stop, from f5.6 to f8, that softness disappears. In fact, even primes tend to be a tad sharper when stopped down. Your image is about the sharpness I'd expect from the lens, so I don't see any problems there.

    • Hmmm.  My cheapest camera is a Wildgame Innovations unit but I haven’t been a great fan of it.  It’s not the NANO version but though, just a cheap one I picked up in a small shop during a hunt cuz I felt I NEEDED one right then.   I do like my old Moultrie and am looking at the M50i as a much updated version of it.   Still comparing their line up.  If I just bought now, that’s what I’d go with.   That WGI 360 sounds like something I have to check out!
    • I have been a Wild Game Innovations fan for most of my time using cams.  I really really like the NANO version they put out.  Compact, only take 4 AA batteries, great battery life and the pictures have been very good quality.  That being said, last year I won a Moultrie Game Spy 2 at a company party and have been very impressed with it.  Same as the Nano, takes only 4 batteries and pictures are very good as well.  These two cameras are now my "go to" and I won't be needing to spend  100's on other cameras when these work great.  The one camera that I am thinking about getting though is the WGI 360 degree camera.  Supposed to be able to take pictures 360 degrees so you don't miss anything moving behind where a normal camera can't detect them.
    • yeah the last couple years have been rather tough for me, but all is good and I can't wait to get back into the stand.  Are you still working the Deployed Soldier/Disabled Soldier hunt at Ripley?  We stopped going as it was just too early in the season and weather was always so darn warm.  Wish they would have held it right prior to the "big" hunts at the end of the month.  Always a good time though.    You'll hear more from me in the time to come and look forward to hearing all your reports of the big one!!!
    • Good yo hear from you again!  Hope your search for property goes well and your time in stand is fruitful.
    • Nice pics jbell! That is a nice yellow garden spider you got there.
    • I had a nice size garden spider on my garage door. It stayed there about 3 weeks. Had a mate who I assume did his business and met his doom. I finally needed to open the door so I safely caught it and let it go in the woods near our house.  Her body is about an inch long. Probably about 3 inches total.       
    • 😄i have several "pet" spiders around the deck and garage. sometimes when i'm bored i swat flies with the swatter and feed them!!!!!!
    • its wierd, my cukes the stems from the ground out look like they were died and dried out but the ends were green, plenty of flowers and producing.quite frankly, i got 2 medium size boxed of cukes in the frig i need to use or give away. i know this isnt right to say, i'm getting cucumbered out.   same with the peppers, i had to look thru a jungle to find them most of the summer as the cukes exploded and basiclly covered them. i have enough peppers for what i need, froze some for chili, and have eaten my share. and again there were no small ones coming in to keep them in the ground to make it till first frost.   my tomatoes, the ones i may be pulling soon are running out of tomatoes worth while . 
    • That's too bad, did your garden get dried out at some point? You had a pretty good start to the season and had a jump on my garden.
