Tone Curves: Final Tips, Tricks, and Things to Avoid

[tweetmeme]We’ve had quite a journey with this whole histogram and curves ordeal:

And now I’d like to wrap things up with a few tips, tricks, and things to avoid when using curves. It’s a fairly simple tool once you begin to work with it and understand it, but there are a few non-obvious items worth pointing out.

TIPS

We’ll start off with a few generic tips for working with curves, then we’ll move on to the some of the more detailed stuff.

TRICKS

Here are a few tricks for the ACR/Lightroom interface under the “Point” curve.

  • Hold Ctrl and mouse over the image to see where the tones lay on the curve/histogram.
  • Ctrl+click over the image to set an adjustment point on the curve.
  • Ctrl+select adjustment points on the curve to delete them.
  • Ctrl+Tab to move between adjustment points without using the mouse.
  • Shift+select multiple existing adjustment points if you want to grab more than one at a time.
  • Shift+click over the image to set your neutral point for white balance (this works outside of the curves dialog too).
  • Shift+arrow keys to move selected adjustment points by 10 rather than 1.

And then we have a few general tricks:

THINGS TO AVOID

  • Watch for vertical sections in your curve — that produces an extremely high contrast and you lose all midtone data in that area.
  • Watch for horizontal sections in your curve — that produces zero contrast and you lose all midtone data in that area.
  • Too many adjustment points will be difficult to manage, just use what you need.
  • Avoid inverted slopes, they invert the tones. Can you roll a ball from the upper right point of the curve to the lower left (without relying on momentum)? If not, you’ve inverted a section of your curve.
  • Don’t clip your shadows and highlights (unless that’s what you really want to do). Keep an eye on your histogram for this one.

I’m sure there are a few hundred other tips and tricks out there for using curves, but I don’t know them all and I couldn’t cover them in one article even if I did. These tips, combined with the previous articles linked at the top, should keep most of you busy for a while. And if you’re looking for more, here’s my final tip on the subject:

Experiment. Try things out, push buttons, make mistakes, and keep learning.

Your Guide to Adobe Bridge: Useful Tips and Tricks

Adobe Bridge Guide Tips and Tricks

In the last part of this series, we went over Organizing your photos with Adobe Bridge. That marked kind of an endpoint for my basic workflow, but I still had a few Bridge features that I wanted to talk about and expand upon.

This article will cover the Bridge keywording features, more productive ways to process RAW files, taking care of dust bunnies, hooking into Photoshop’s batch processing feature, and clearing up some visual archive clutter with stacks. This article also marks the near end for the whole series, and the final article will recap everything we’ve talked about.

IN-DEPTH KEYWORDING

Back in the File Preparation article, I briefly mentioned keywording, but I didn’t talk a whole lot about how to do it. Keywording can be done in one of two ways with Adobe Bridge: typing semicolon-separated keywords into the Metadata Panel or clicking the check-boxes in the Keyword Panel. I use both methods depending on the situation.

Adobe Bridge Keywording Via the Metadata Panel

Keywording via the Metadata Panel is generally faster than searching through lists of keywords that you have archived. The problem with using this method is that it can’t be used when you have multiple images selected that already contain different keyword values. In the “Keywords” box you’ll see “(Multiple Values)” rather than the keywords. If you type anything in that box, you replace whatever information was there with the new information. So this method of keywording is good for groups of images with no previous keywords or single images regardless of their keyword situation.

Keywording via the Keyword Panel is a little slower than typing things by hand. The nice thing about it, though, is that it can handle adding keywords to multiple files with pre-existing keywords (even if they’re different from each other). The other great thing about the Keyword Panel is that it serves as a keyword archive and it sort of reminds you to use keywords that you may have otherwise missed. I’ll typically use this method of keywording for the more detailed work after the images have already had a first coat of keywords.

Adobe Bridge Keyword Archive

USING THE KEYWORD PANEL

Organizing the keyword archive is fairly simple, but it’s not a completely automated process. When you keyword things by hand in the Metadata Panel, Bridge makes a note of this and places these keywords and phrases in your Keyword Panel under “Other Keywords”. These keywords can be moved around and stuffed into other categories for permanent archiving.

To create a new category, simply click on the plus sign at the bottom of the panel for a “New Keyword”. This inserts a top level keyword that can be used as a category or grouping for other keywords. Once you have some top level keywords, you can add “New Sub Keywords” by selecting they keyword you want it under and clicking the plus sign with an arrow next to it. Sub Keywords can even have their own Sub Keywords, as shown in the screen shot for my “film” category.

Moving and organizing existing keywords is simply a drag-n-drop operation. Keywords can also be renamed and deleted. The easiest way to build up your keyword archive is to do it as you go. Don’t bother spending hours plugging in keywords that you think you’ll use later — make good use of your time and do it while you’re actually keywording photos. And one last tip for the Keyword Paneltry to keep your keyword groups filled with less than 10 or 15 keywords. Any more than that and you can probably create some new sub-groups. Too many keywords in one list only makes it more difficult to find them.

Do your keyword archiving correctly and adding those words and phrases will be a snap. You’ll be amazed at how many keywords you would have forgotten if you hadn’t run down your list and started diving into your categories and sub categories.

COPY AND PASTE ACR SETTINGS

As I mentioned in the File Processing article of this series, you can process multiple images inside of ACR to speed things up. Well, we can do the same thing without even bringing the images into ACR or Photoshop. If you have a group of photos with nearly identical lighting conditions and exposure, you can process one file and apply those settings to the other files from Bridge (I also mentioned this as an afterthought in the article).

To review: after you process your file, select the thumbnail inside of Bridge and copy the “Development Settings” via the right click menu, edit menu, or press Ctrl+Alt+C. Then select the images you want to apply the settings to and use the menus or press Ctrl+Alt+V to bring up the dialog that lets you choose which settings to paste over.

Adobe Bridge Spot Removal

One of those settings is for “Spot Removal”. A neat trick you can do if you have a bunch of images with nasty spots on them, is to remove the spots on one image (via ACR’s healing tool) and do a copy & paste to the other images for only the spot removal. Now you don’t have to click every spot in every image.

BATCH WITH PHOTOSHOP

One thing I absolutely love about Bridge is the ability to batch process photos with Photoshop Actions without manually opening those images in Photoshop and running the actions. If I process a photo with ACR and it doesn’t need to be opened in Photoshop, I don’t open it in Photoshop. But if I want to post that photo to Flickr at a smaller size, correct color space, etc., I have to use Photoshop.

But since I created a few actions for resizing my Flickr photos, I can carry out that task as a batch process. Just select one or more photos that you want to batch, go to your “Tools” menu, navigate down to the “Photoshop” menu, and select “Batch…” to bring up a dialog box. In fact, it’s the same dialog box that you can access from Photoshop itself.

The “Batch” dialog gives you options for the photo source, destination, and errors. Explaining every option in this dialog would constitute an article of its own, so I won’t mention everything about it. When I’m working with Bridge, my source will be set to “Bridge” — this just uses your previous selections for the batch. I also suppress open file dialogs and color profile warnings to ensure that the batch can run uninterrupted. These things can be dealt with in your Photoshop preferences. For my destination, I leave it as “none” when I’m just resizing for Flickr since my action saves the downsized file.

USING STACKS

Adobe Bridge Stacks

Do you ever end up with hundreds of photos from a single shoot that end up in a single folder? Are any of those photos basically the same as some others? If you don’t want to get rid of those similar photos, you can at least condense your archive visually. Stacks are kind of like miniature folders, but without the folders.

To create a stack, select the similar images and press Ctrl+G to “Group as Stack” or use your “Stack” menu or right click menu. This brings all the selected photos together and frees up some space on your screen. The stack can be expanded, condensed again, or ungrouped (check the Stack menu for the shortcuts).

I don’t typically use them unless I have a lot of photos in a single folder. They’re handy if you like to go crazy with the rapid fire, because a lot of bulk comes from all those slightly different photos.

WHAT’S NEXT?

That’s pretty much all I’ve got in me at this point. The last article in this series will be a recap, or course outline, for everything we’ve covered. I’ve only been using Bridge for a few months now, so I’m sure there are other features, methods, and tricks that I haven’t touched on. There’s always a possibility for a follow-up article sometime down the road.

If you guys are interested, I could possibly start another series on Adobe Camera RAW. I’ve been using it heavily for a little while now, and I’m getting to the point where I’m comfortable with the basic stuff for working with color and black & white photos. It’s really not that scary! And it uses the same RAW processing tools at Lightroom.
