    Hey Marc,
    Thanks for sharing this detailed approach (or at least part 1 of itthumb.gif). My only question is in your leaving the default brightness and contrast settings in ACR. I had seen a video by Martin Evening URL="http://lightroom-news.com/2009/03/21/exposure-and-brightness-adjustments/"]link[/URL a while back about the use of brightness and exposure in LR and, since then, have changed my default brightness to 25 so that I now use the exposure slider much more to adjust the overall 'brightness' of the image. I would love to hear your take on this.
    Thanks,
    E
    Great questionclap.gif

    IMO the sliders used and the order in which used is all image dependent.

    Because this image is predominantly dark and shot at 400 ISO I did not want to increase the noise by increasing the brightness too much.

    What I really wish is that one could depress the opt/alt key on the brightness slider as well.
    The BIG diff between the brightness slider and the exposure slider is that they effect diff areas of the curve.
    The brightness slider will not effect the end point or highlights in most cases. This is only because on some images if you crank the brightness slider up too far the highlights that you previously set in the exposure slider will become blown:cry
    For this reason and this image, I left the brightness slider at +50. This increased the values in the mid tones and shoulder (leaves) of the tone curve without effecting the white point. The exposure slider being set at -.55 allowed me to retain as much of the blown highlights as possible and with the brightness slider set to +50, also maintain slightly lighter values in the trunk and leaves.



    I actually believe his vid is confusing.

    What scares me the most about his vid is his statement that "you dont need to look at the histogram while shooting in RAW, only concern yourself with this when shooting jpeg"
    I always view the histogram, EVEN WHEN SHOOTING IN RAWdeal.gif
    He goes on to state that you have FULL control in LR or ACR.
    IMO you really dont have FULL control, but rather limited. I know it is WAY more control than a film work flow ever allowed, but not FULL.



    You only have FULL control if you consider the camera and software as one tool linked together by your vision and FULL understanding of all their secrets, limitations and potential.

    I am still working on that part myselfwings.gif

    Maybe I need to make a tute about Chromatic aberration in RAW, as it really helps my glass a bit anyway

    Great Idea Jim

    Hi, its been awhile since I visited Muench University so I went back through the posts for the last few months and learned two things that I have not been doing regularly. The first is with chromatic aberration-- I usually correct this if I notice it, but in the example Marc set the image to 300% and then corrected visually-- is this the best way to do it? Also, something I did not know was about holding option with the exposure slider to correct blown highlights. I have been using the Recovery slider- is one better than the other? Also, I pulled up some images in my trash folder because they were blown just to try it, and I found that I had to slide past the point of the screen being totally black ( I guess bc they were so blown out) in order to correct properly. This then obviously results in the whole image being underexposed- do you then mask the two different exposures as separate layers to combine in PS? Thanks for the help I'm very happy to be learning these new techniques and uploaded a couple of images that hopefully marc will critique.
    Thanks,
    Chris

    Everything I know about chromatic aberration correction I learned from Marc - so -- Yes, to evaluate for CA, you need to look at the image at 200% or 300 % in size. I usually try to look out near the corners, to see if there is a consistent pattern of CA, either Red/Green or Blue/Yellow. R/G is usually far more prominent and pervasive than Blue/Yellow. The first thing I do, is turn on Defringe to ALL and recheck the image for CA. Sometimes, Defringing is all that is needed - fast and easy. If R/G remains after setting Defringe to ALL, then I slide the slider to remove the R/G CA visually. Usually you can kill it all, sometimes you have to accept just making it a bit better. Sometimes the Blue/Yellow slider needs to be included as well.

    You will find there is a bit of a learning curve to do this well - at first it seems kinds of unpredictable, but with time it gets easier and faster. Primes usually take the same settings for most images, but zooms will have more unpredictable needs depending on focal length used and distance from the sensor plane.

    Regarding the Exposure and the Recovery sliders for over exposure. You can set your image so blown pixels are displayed in red, but I prefer to hold the option key down as I adjust the Exposure slider to show me the fried pixels. Generally, the Exposure slider sets the white point, and then you adjust the blackpoint with the Black slider. Then you can use the Recovery slider to help bring back the highlights after setting the exposure slider. The Recovery slider will really help correct over exposed pixels. I rarely use this sider greater than mid point, but there certainly can be exemptions to this.

    Raw gives us more room to salvage over exposed images, but there are still limits. If I can't correct an image with modest use of the sliders, I tend to bin it. Yes, you can make two separate exposure from a RAW file, and then recombine them as Smart Objects in Photoshop.

    Hey Chris,

    Yep, we're in Round Five. It's linked in the body of the instructions as the word "HERE", not at the bottom. The bottom ones are just the archived galleries. Sorry about the confusion!

    Are your photos here? http://dgrin.smugmug.com/gallery/8570317_wuSfN

    It's also worth it for anyone who's submitted images to leave a comment with their username if it didn't automatically do it. It just makes Marc's life a little easier :D

    No need to appologize for my failure to read the whole post, Schmoo... that's my fault! Thanks for pointing me to the right spot!

    Curiously, the captions appear to have picked up the jpg name instead of the body copy from my email... not a big deal, I'll comment to add my user name now, just trying to say that I read part of the first post and followed the instructions! :D

    Hey Schmoo.....

    Thanks for administering all of this. I just sent in a photo, and it didn't pick up my username or title in the caption. It's the one that just says "Lake" (which was the filename).

    I tried clicking "Add Comment", but it wouldn't let me.

    Another sunset

    Great composition
    Good depth of field
    Good subject
    Post processing is too dark
    Color balance does not appear natural


    I like the mood, location and choice of lens in this image. However, there are three things bothering me about this image. The most important is the dark rocks, which may have been dark in reality but appear too muddy in the presentation here. The other is the color of the rocks, which is spilling over into the clouds, and I think is also contaminating the blue of the sky. I do enjoy the small boulder balanced on the top of the large one which is part of the reason I appreciate your choice of composition. The third problem is the point of view, which I think could have been lower. This would shrink the amount of mid ground, forcing the quartz vein in the foreground closer to the large boulders on the horizon.

    I am impressed by how much better the edited version is with the darker and greater contrast in the near subject, and the lowered contrast and lightened background far away. I must remember to try this with some of my images,. Very nicely done.

    I too need to remember this! How in the *%$&^* do you remember all of this?

    Sometimes when I wake up I can't remember where I am, who I am or why I am in hand cuffs.

    So are we still on ... round 6? Since round 5 closed May 18, 2010?

    I'll have to look through my stuff, see if there's anything that's even CLOSE to the level of polish as what's in the galleries already!\

    Edit: Yes, I found three that I've been working on recently, and those are up now in the Round 6 gallery. The username & title from the body did not get into the title, so it's still the "DSC 0045" filename that's associated with the pictures. Comments on the picture underneath for keeping track.

    Neat stuff - I've been looking through this thread whenever I get a chance.

    This is your chance to have a one-on-one critique with master photographer and all-around great guy Marc Muench. We've all seen him active in this forum, been awed at what he can do with his camera, read his publications and we know that he has no fear dishing out honest feedback.

    To take Muench University's course in landscape photography, here's what you do:
    1) Choose up to 3 landscape images of your best work. Post-processed, edited, what you consider to be finished and polished images.

    2) Resize your photo to 1024 pixels on the longest size. This is just to be sure that we're working from display copies. If you use Smugmug, this is the XL size.


    3) Submit your image to our gallery using the new Guest Upload feature of Smugmug. To do this:
    • Point your browser to this URL: http://www.smugmug.com/photos/guest/6vRJZW/MuenchU
    • Drag and drop, or use the Browse feature to add your photos, then press Done.
    • Post a Comment for each of your images containing your Dgrin username, and a title. I (kdog) will move your comment to the caption field of the photo.
    4) You may want to subscribe to this thread so if your image is selected, you'll know about it. You can set up subscriptions and notification methods in your Dgrin control panel.
    Marc will choose an image from that gallery to critique. If your image does not get chosen, you can always submit more entries for the next round. Remember that we can all learn from the conversation - even if the image isn't our own! When Marc is done, he'll move on and choose the next image, again at his choosing.

    The conversation that will follow is between Marc and the chosen photographer. You are invited to follow along, but it is a dialog between the two. We have an open forum [thread=88306]right here[/thread] where you all can chit-chat all you want about what's going on in the main critique. We will move any stray posts in this thread.

    This is the big time, folks! Please no whinging, sour grapes, or drama. Have fun... and go learn something! :D


    View the full array of stunning submissions right here in the archives: Also you can see the entries for the current round here: Round Seven Gallery


    Is there a way to remove an image that I thought I had already removed and replace it with another?
