    Default (New image)No, you cannot have it!! replaced image using new sharpening technique

    It was just 45 min before sunset at Viera a couple weeks ago when I saw this red-shouldered hawk. He had just caught his dinner, but there were others above waiting to steal it. Taken with my D300, tamron 300 2.8 + tamron pro 2.0 TC, f9.0, 1/1250,EC -.67, iso 800 matrix metering. PP in NX
    C&C always welcomed
    After LAB mode sharpening


    Before LAB mode sharpening


    I know it is more than one, but just this time for comparison sake, please.

    Default Hi Nancy

    The red shoulders certainly are cooperative at Vierra :)

    This one seems too soft to me. I'm looking at it on my work computer but I don't think that that's the issue.

    Perhpas the 2.0 TC is the cause here?

    Well, possibly the 2.0 TC, which I will not be using much after getting the 500. But, I also found that at the higher iso's one cannot sharpen as much as at the lower ones. I have the same shot but at iso 200, with the same setup,and was able to sharpen more.

    That lens is good enough to produce a sharp image with the converter Could be other factors

    You can sharpen at higher ISO You just need to do thing different One possibility is selecting the bird and sharpening That will avoid sharpening the bg noise

    Other possibility is sharpening LAB mode > lightness channel Won't sharpen noise !!!

    ....oh forgot if you send me a PM with your name I can update your profile We are trying to have all actual names Thanks

    Thanks Al! I will have to try the LAB mode technique you described. PM sent.

    Well, I tried the LAB mode sharpening way as Al suggested. Very good Al!!! I love learning new things like this!

    Well I do love the stately pose of this beautiful hawk. I'm not sure whether he is boldly showing off his catch are daring you to touch it....and live. As the others have said...a tad soft. It's been so long since I used LAB sharpening that I'd actually forgotten about it. I would think it would work nicely here. It would be nice to see a comparison of sharpening...and a final product.

    Added comparison images. Just this time for two please:)

    Ok if you will pardon my newness, what is LAB sharpening? I have several images that aren't quite sharp and
    am just beginning with editing.
    Thanks

    Hello Nancy and welcome.

    The composition and BG works for me very well. You already fixed the sharpening issue. The Hawks looks very alert which adds interest to your image. Nicely done!

    Nancy,
    Welcome to BPN.
    In the future when you want to compare 2 images, let me suggest that you create an image that would contain both examples. Doing this will allow a closer side by side look. The down side is each will be smaller due to size constraints.

    Or post one image in the original post and post the second image as a reply.

    That way it is win / win. Just one image per post as stated in the guidelines and you still get to show both!

    We are a learning and teaching forum. And your images are great examples of how to teach using this format and forum.
    Thank You.

    Thanks James

    PS I will have BPN # in a few moments.

    Hi Nancy,

    Never got to meet you in person, but I know your name form other sites.

    Let me extend the red carpet for you, my dear, and big welcome to BPN.

    Hawk is looking good :) I would loose some of the left.

    Will PM you when we visit Viera. You need to get HarryB here, been too busy to e-mail anybody :o Please act on my behalf and ask him!!!

    Thanks :)

    Hi Nancy,

    Nice capture and I can see the subtle difference. You will have to fill me in a bit more...see you Sunday.

    The sharpening seems to have helped. Nice posture and color.

    Note that every time you change modes the image is degraded some. If you want to achieve the effect of LAB mode sharpening, one route is to duplicate the image onto a new layer, sharpen the layer, then set the blending mode of the sharpened layer to luminosity. Same effect but nondestructive. You can also slightly oversharpen and adjust the opacity to taste, make a layer mask to mask off parts that you don't want sharpened, etc, etc.

    I have never found a convincing reason to do anything in LAB mode, always being able to find an equivalent procedure while remaining in RGB mode, producing the same effect without the losses entailed of switching back and forth. For instance, a common color enhancement technique uses a steepened curve adjustment on the AB channels in LAB mode; the same effect can be achieved using the same curve on a curves adjustment layer in RGB mode with the blending mode set to "color".

    I did read more about LAB mode and discovered what you have just stated, thank you. And, I ended up finding how to do the same thing in NX, so without changing modes.:) All in all a great learning experience.
