Landscape Astrophotography Tutorial - First Night Out from Ben Canales on Vimeo.

One more thing I forgot to mention -- if you want to do the Reverse Lens Macro E.C., you CAN do it with one lens. You can flip your lens around and put it flush up to your camera. You have to get really close to whatever you are shooting, and have a lot of light, but you don't need two lenses back to back.
Ask me about it in class and I can show you!

Hey folks.. great job working on your own with the Photoshop exercises.
Thursday we'll have a couple things going on:
1 - shoot your food shot
2 - edit your food and unusual composition shots
3 - finish any Photoshop you didn't get done today (I think everyone that was here got it done)
4 - meet with Andy to talk about your assignments again
^ Not necessarily in this order! No lecture!

Photoshop Assignments for June 21-23
These will be due at the end of class Thursday June 23, but some of you might be done with it on Tuesday if you're not shooting in the studio. We have three photos to edit!
#1: Selective Color
Selective Color is an effect for desaturating everything except certain parts of your image. We're going to use an adjustment layer with a mask, which is a very powerful concept in Photoshop and can be used to make a lot of advanced adjustments.
1. Copy this photo to your desktop.
2. Open it in regular Photoshop (you can drag it down onto the Photoshop icon in the doc or open Photoshop and go File → Open).
3. Go the the Layer Menu then New Adjustment Layer → Black and White… (and click OK)
4. Click "B" to select your brush
5. Black reveals, white conceals. Make sure the color at the bottom of the tool bar on the left is set to black.
6. Start painting the tomatoes! A couple notes:
• Make sure your brush is set to something round click on the brush picker in the upper left corner. Set the hardness to 25%.
• You can change the brush size with the bracket keys ( [ for smaller, ] for larger)
• Work goes quicker with a larger brush
• If you make a mistake, set the color to white to conceal
7. Paint so that only the tomatoes are in color. Before you are done, note that you can click on the "Black and White" adjustment layer you created (in the Layers window) to tweak the tones of your image. Try playing with it a little.
8. Save at JPEG quality 8 and upload to Flickr as Selective Color Practice.
#2. Clone Stamp
The Clone Stamp tool can be useful for removing unwanted objects. Just note that it is unethical for photojournalists to use it.
1. Save this photo to your computer. Open in regular Photoshop.
2. The ninth tool down on the left tool bar is the Clone Stamp. We'll be using it to get rid of the boat and bird so it looks like this.
3. To tell the Clone Stamp where to sample from, hold down the option key and click on the photo. Now, when you release the option key and move the mouse around, you'll see a preview of what it will look like if you start "painting." You might have to adjust the brush size with the bracket keys -> [ and ]
4. The bird will be easy. Sample some blue sky and paint over the bird. The boat will be trickier. A good starting place is sampling right on the edge of the water, then start painting in the same relative place where the boat is. Ask Andy for help if needed.
5. Save as a JPEG and upload to Flickr as No Boat!
#3. Compositing and Gradient
This one is a little tricky and gets into some advanced features of Photoshop. Compositing can be useful when you need to combine two images or take out a background and replace it with a solid color or gradient.
Apple With Gradient
1. Download this image and open in Camera Raw
2. Fix the contrast and color balance. Go to the HSL sliders tab and adjust the hue/saturation/luminance of the red slider so the apple pops. Increase the luminance and saturation of the green slider so the worm pops out more. Example.
3. Click the "Open Image" button to open in Photoshop.
4. Use the Quick Select Tool (W) to select the apple. Click and drag inside the apple until you have the "marching ants" along the edge of the apple.
5. Hit the "Refine Edge" button, middle top. Click the "Smart Radius" button. Increase the radius, smooth, and feather sliders slightly to make the cutout a little cleaner.
5. Once it is selected, copy it (Edit → Copy) and paste it into a new layer (Edit → Paste)
6. Hide the background layer by clicking on the "eyeball" next to it in the layers window
7. Go to Layers → New Fill Layer → Gradient. Click OK.
8. Change "style" to Radial and click the "Reverse" button.
9. This is a little tricky… ask Andy if you aren't sure where to pick but see this image. To change the gradient to blue, click on the color box, then and find a nice shade of blue in the color selector.
10. Click OK in windows until you're back in your workspace.
11. In your layers window on the right, drag your gradient layer below your 2nd layer so the blue gradient appears underneath the apple
12. Save as JPEG, upload to Flickr as Apple!

Part I of a 20-part (!) retrospective of World War II photos.. this week: Pre-WWII.
Also, I created a new assignment group on the right sidebar because the other one was getting a bit long and cumbersome to update in Blogger!
