Rainy Day Assignment: Eye Manipulation


Hello Students,
For this rainy day assignment, open your previous image you took for the eye and face manipulation and modify it to have different sets of eyes.

Eye Manipulation Assignment:
  • Take a photo with shallow depth of field, closeup on the face and eyes
  • Open original face picture
  • Search for eyes online with Google Images
  • Download images and edit your photos to create 4 final examples of eye manipulation
  • Create an image that shows Cat Eyes
  • Create an image that shows Goat or Snake Eyes
  • Create an image that shows Evil Eyes
  • Create an image that shows Techno Eyes or your choice of effect
  • Use airbrush techniques and layers to make the eyes look as natural as possible

HDR Pro Project

Hello Students,
Your new assignment is to shoot a set of bracketed exposure images and combine them with Photoshop's "Merge to HDR Pro" feature. HDR Pro is a powerful tone mapping program, and is the best way to merge multi-exposure images.

Project Requirements:
• You will produce four final images for this project.
• You must use a tripod to shoot a set of multiple exposure images. and then combine them with the Merge to HDR Pro feature in photoshop. Take 3 different exposures, underexposed, normal and overexposed.
• Write down the shutter speed, aperture and ISO for each image you take, HDR Pro needs this information!!!
• For your first image you will merge the separate exposures and use the sliders in the HDR Pro interface to achieve your best desired look.
• For the other 3 images, reload your separate exposures in HDR Pro and choose your 3 favorite Presets from the Preset Menu.
• Upload your 4 final images as jpgs to your blog when complete.
• Subject matter is your choice, but avoid any portraits or any subject that will move between taking each picture. HDRI processes best with landscapes, cars, architecture and objects that have rich texture or very shiny surfaces, like cars. HDR Pro can align your images, but if there is too much movement between exposures it wont work. Use a tripod, it is mandatory for this project.


Merge to HDR Pro with Photoshop CS5:

  • Take your 3 different exposures and place them in a new project folder
  • Launch Photoshop and go File > Automate > Merge to HDR Pro
  • Browse to your files and load all 3

  • Merge to HDR Pro launches
  • Input the Shutter Speed, Aperture and ISO for each exposure

  • Modify the sliders as outlined below to achieve your best look
  • Check out the Presets at the top for your other 3 versions



Setting Camera Up for Bracketing:

Introduction to High Dynamic Range Imagery (HDRI)



Hello Students,
Your next assignment is to create 3 "mock" HDRI Images with photoshop. Follow my process below very carefully for success. Check out this  link of cool HDRI Images for inspiration.

 

Project Requirements:
• Shoot 3 new photographs using a DSLR, your images should be high resolution. The more image data the better. The subject matter is your choice, landscape, portrait etc. Choose images that have good color variation and are properly exposed and in focus.

• Process each image with the steps below, post a before and after version for each image to your blog upon completion.

Simplified HDRI Process with Photoshop:
You can make a "mock" HDRI image from a single photograph with photoshop. Normally creating an HDRI image requires multiple exposures. We will try creating one with a single exposure. The results should add a big color boost to our photographs.

Step 1) Open your image in photoshop. Rename your background layer to "Original".

Step 2) Create a duplicate layer and rename it "black&white". Go to Image > Adjustments > Hue and Saturation. Pull the saturation down until your image loses all color. Now change the Blending Mode to Overlay. This is located on your Layer Palette.

Step 3) We need to "invert" or reverse the "black&white" layer. Go to Image > Adjustments > Invert.

Step 4) Now we add some blur for that airbrushed look. Go to Filter > Blur > Gaussian Blur. I used a Blur setting of about 40, if your photograph is lower resolution than our classroom DSLR you may need to adjust this number. Adjust till you achieve the desired look.

Step 5) Now duplicate your "Original" Layer and place it above all other layers. Rename this layer "Linear" and change the Blending Mode to Linear Light. Lower this layer's opacity to about 60, or adjust to your desired level.


That's it your done! Repeat this process with 3 different images and place a before and after version for each image on your blog.
