Tipsheet: Photoshop

A link to a great UC Berkeley tutorial is also available over on the right, under Photography tips.

Very basic PhotoShop tips for processing your images for Soundslides, by Florangela Davila

Using some type of imaging system – PhotoMechanic, Adobe Bridge – do a quick edit of your photos. Look for a variety of shots – close-ups, environmental, portraits, details, quirky. A good rule of thumb is about 15 images per minute of slideshow. You don’t want to ever have to repeat an image – or use a less than stellar one – so shoot a lot.
Dump your images into a folder and give it something easy to find: FunForest-images-raw. It’s also a good idea to have a print out of your contact sheet with all your images. This makes it easier to keep track of what your work flow.
Now create a new folder and call it something else: FunForest-images-slideshow. This is where you’ll be storing all your newly processed images. (These are the images that you’ll move over to Soundslides so it helps to be organized).
Open PhotoShop.
(I’m told you can download a trial version for free, for 30 days, via Adobe)
Upload an image.
Look on the top bar across the page for the magnifying glass.
Click on it to magnify the image. This is helpful to look at “noise” and to see how you can reduce it.
Reduce the “noise” in an image. Noise: those “specks” or blotchy patches in an image.
Note: when in doubt defer to the automatic setting.
Filter >noise>reduce noise.
Crop your image using this tool.  Hint: put your cursor at a corner that you want to use and then drag it along.
Crop size: 800px by 600 px
Remember: use px or else it will default to inches.
HINT: If your image looks super small after doing this go to “View” and use “Full size.”
Remember to use the rule of thirds when cropping. Remember not to crop out limbs or anything that looks “painful.” (Page suggested: don’t cut at the joints) But tops of heads are OK since that forces the viewer to look for the eyes.
What Kenny Irby says: “Cropping is the accepted step of editing… it offers focus and clarity when done with professionally.”

If your image is not horizontal – if it’s got some weird angle – readjust it using the ruler tool.  Find the “ruler” —  by right clicking the eyedropper tool.
Click on any “line” in the image and trace it across.
Image >image rotation>arbitrary
Adjust the “tone” in an image. (Lightness, darkness, balance in an image)
Layer>new adjustment layer>curves

Put your cursor on the “curved” line. Then stretch the line, make it wavey. See what happens to your image.
NOTE: The channel reads “RGB” which I believe is what we want.
Note: Instead of using your cursor try using the arrow keys on your keyboard. It allows you to adjust expertly.
Note: Aim for an “S” shaped curve.
Adjust the hue/color saturation. (You want to stay away from hue and lightness because your “curves” tool is better. So stick to saturation.)
Layer>new adjustment layer>hue/saturations

Slide over to the degree you want.
Sharpen at the end.
Hint: Yes, at the END.
Use the magnifying glass to enlarge one spot in your image. (Go for the eyes, or hair)
Filter>sharpen>unsharp mask
It’s a handy idea to give your images caption information in Photoshop. This is info that can easily export into Soundslides and it will save you time, versus doing it there.
File>file info>description>description box
In the description box write up the caption. (See handout).
Save.
Save for “web and devices.”
HINT: This is important. WEB AND DEVICES!!!
*****Save everything as a .jpg.
HINT: If you decide to do a text slide you MUST ALSO save this as a .jpg.
And make sure the box that reads “Convert to sRGB” is checked. (Why? Read way below).
HINT: Give your new images a descriptive name –cupcake close up; bakery outside – so it’s easier to identify. This will come in extra handy if you decide you want to delete images from your slideshow.
Save save save and back up back up back up.

Here’s a great Youtube video on curves.

And a really good one on hue/saturation.

Page gave a nice explanation of the sharpening tools.
Here’s a video I found that gets a bit fancier.

And lastly here’s one on text slides. You might want one of these NOT for the opening but for the ENDING. As in “Photography, audio and production by Awesome Student.” Note: Stick to straight fonts and straight lines. No warping, no fish eyes. And if you decide to use text slides WITHIN your slideshow that is alright. Although it may seem gimmicky and so you better be ready to argue why you needed them. Don’t use a text slide because you got a lousy interview
However, I’m open to an opening text slide if your piece really merits it.

Convert to sRGB
“Did you ever wonder why images that look perfect in Photoshop appear much less saturated when viewed in a web browser? If you’re using Adobe RGB, Ekta Space, ProPhoto RGB or one of the other large-gamut working spaces the reason is simple; the majority of Web browsers do not implement color management (the exception is Internet Explorer on the Mac). They display images directly to the screen without any adjustment for the image’s color space or your monitor. Since your monitor’s color gamut is smaller than these color spaces, image colors will get compressed to fit within the gamut of your monitor, causing them to appear less saturated (see Figure 1 below).”
The above comes from http://www.naturephotographers.net/articles1002/mh1002-1.html
