Jumping Matrix Style with help from layer masks

in

Yours truly leaping a chasm! This is a blending of 4 different action shots using a simple layer mask technique.In case you missed it last week, I do take time away from being behind the camera to continue my love of rock hopping and leaping objects (see here).  I made the leap over the above chasm-ish span several times each time trying to go further.  I did not actually move fast enough to be seen multiple times in 1/500th of a second.  How I made the above image was to combine four of the shots taken in one burst of shots on my Nikon D300 (capable of 6 frames per second).  Since the DSLR was on a tripod all the background matched up perfectly, as does the exposure since that was set manually.  The only thing moving over the series of shots was me.  Then, it was just a matter of using layer masks in Photoshop to produce the multiple exposure, or Matrix, looking image.

These shots layered on top of each other produced the above shot.Using layer masks to blend multiple images is not a difficult type of digital photography editing.  I have written a tutorial on how to use layer masks here.  Give this photography tip a try and post your results in the comments below!

How to fix black clouds in HDR images using layer mask

in

HDR photography and images are very popular right now.  I, myself, have participated in a local exhibition featuring only HDR images.  The thing is, I do not care for 90% of HDR photography I see.  There is a large debate about processing HDR images to look more real or more hyper real.  I am not referencing that debate here.  For me, a simple reason why I do not find a vast majority of HDR images appealing is because they suffer from horrible shadow effects as demonstrated in the black clouds in the center image above.  As you can see with the single exposure photo, the sky looks good, but there is no detail inside the glass.  The 7-bracket HDR image reveals what is under the glass and adds better color, but at the expense of the clouds.  Therefore, the best final results come from blending the single exposure photo with the 7-bracket HDR image.

1. click on add layer mask (sorry, shows vector) 2. click on layer 1 3. paint with a black brushBlending two images together is not a difficult time consuming process using Photoshop.  The screenshots in this post are using CS5, but other versions should basically be the same.

First, open the single exposure photo and 7-bracket HDR image in Photoshop.  Drag the 7-bracket HDR image on top of the single exposure photo.  Once you do this you will only see the 7-bracket HDR image.  The single exposure photo is completely hidden underneath.  Our goal is to reveal only the parts of the single exposure photo we want, in this case, the clouds and sky.

After you have dragged the 7-bracket HDR image on top of the single exposure photo, follow the three steps highlighted in the screenshot above: 

  1. Click on "Add layer mask"
  2. Click on "Layer 1"
  3. Select the Brush tool: soft brush setting, black, 60% opacity (or similar, just not 100%) 

Now using the Brush tool at the settings described above, slowly brush the areas you want to reveal.  The 7-bracket HDR image starts to disappear revealing the single exposure photo below.  In the above screenshot you can see that I already revealed the nice white clouds on the right side.  Here is an extra tip:  I also used the Brush tool on the concrete wall of the building that looked too black & dirty to reveal the cleaner wall from the single exposure photo.  If you make a mistake and reveal something you did not want to, set the Brush color to white and the top image will return.

Here again are the before and after results.  By using a layer mask you can create a dynamic hdr image and still maintain the clean look of clouds, walls, etc in the image.  This vector mask technique is great for other photography tricks too.  Want to change the background on a portrait?  You can do that following this same process! (see results here)

Try the vector mask process on some of your images and be sure to post links to the results in the comments below.

    • Layer Mask Photoshop CS5 Digital Photo Editing Lesson with Ed

    in

    Using a layer mask in Photoshop CS5 to change the background of a portrait - book your lesson today to learn tomorrow!

    I met Ed from Jacksonville again this morning for our second of two Photoshop CS5 centered DSLR Photography Lessons.  After giving him a crash course on the basics of using many common Photoshop tools yesterday, today we focused mainly on one thing:  layer masks.  As seen in the image above, if you take a texture, drop it onto a portrait, create a layer mask, then "brush back in" the portrait, you have a very quick and easy way of completely changing the background of a photograph.  You could also keep some of the texture visible over the portrait subject as well to create a different look to the entire frame. 

    This layer mask technique is also very useful for fixing clouds in HDR images, which often turn out too dark.  Using one of my own HDR shots as an example, I showed Ed how you can get the benefit of an HDR image without the drawback (dark clouds) by taking a single frame of the bracketed shots that has very white clouds and using it as a layer mask to blend into the HDR image.  I will be posting this tutorial using the HDR example later this week.

    The four hours (total) I spent showing Ed what I know about Photoshop went by very fast.  We easily could have filled another four.  He took detailed notes so I am confident that with what he learned during our intensive lessons he will be able to apply to his own images and begin teaching himself how to use more features of Photoshop.

    Introduction to Photoshop CS5 Basics & Keyboard Shortcuts with Ed

    in

    Grand Tetons photograph by Ed, editing by Jason - the lens correction filter in Photoshop CS5 sets things straight 

    I received a phone call from Ed all the way in Jacksonville (about 3 hours away) asking about taking extended 1-on-1 Photoshop CS5 lessons.  I am not a certified Photoshop expert or anything like that so at first I wanted to make sure he was not looking to learn how to do something like someone's face and put it onto another person's body.  My Photoshop skills lie mostly in the areas that pertain to editing digital photographs, not graphic design.  After talking for a few minutes though I realized that what Ed wanted to learn I could most definitely teach.  We booked two lesson sessions, one for today and another for tomorrow.

    Ed had his own photos to use during the editing lesson and I was pleasantly surprised to see the Grand Tetons.  Florida photographers of course have no local opportunities to photographs mountains of any kind.  Ed's photographs already looked good, but there is almost always something that can be done to improve any photograph, and for sure any published or portfolio photograph by a serious hobbyist or a pro has had at least some editing done to it.  I am not afraid to say that editing is often 50% responsible for the final look of a photograph.  

    The example above did not need that 50% level of editing.  I showed Ed my workflow which starts with cropping (I cropped the photo even more here than I did during the lesson to better show the edits we made) and then removing any dust spots on the sensor that appear as dirt blemishes in the photo by using the healing brush (keyboard shortcut - j).  Then I taught how to use the quick select tool (w) to highlight only the mountains for a contrast adjustment.  Then the foreground grass and fence were selected for a color balance boost.  Lastly, we used unsharp mask to increase the overall sharpness of the image resulting in more defined blades of grass and details in the fence and mountains.  

    Tomorrow we will move on to editing portraits and using layer masks.

    Digital Photograph Editing Lesson with Chris

    in ,

    Selective contrast edits in Photoshop can make a big impact on your photos - image used by permission 

    Chris took his first DSLR Photography Lesson on Tuesday where we went out into the field to practice shooting.  For our second of four lessons Chris wanted to learn digital photograph editing, which I believe is a very wise thing to do (read more here about my feelings on learning shooting & editing at the same time).

    The cruise ship is Chris' own photograph.  The original is well composed with good contrast in the foreground plants.  However, the cruise ship itself appears to be covered in a haze.  I taught Chris the following techniques using Photoshop CS5 to selectively enhance the cruise ship first, then the water, then finally the sky.

    For the Cruise Ship: 

    • Use the Quick Select Tool (W) to select the entire cruise ship
    • Go to Images --> Adjustments --> Brightness/Contrast
    • Increase contrast to your preference 

    For the Water: 

    • Use the Quick Select Tool (W) to select the entire water area
    • Go to Images --> Adjustments --> Brightness/Contrast
    • Increase contrast to your preference
    • Go to Images --> Adjustments --> Color Balance (Command-B)
    • Enhance the color sliders to your preference

    For the Sky: 

    • Use the Quick Select Tool (W) to select the entire sky
    • Go to Images --> Adjustments --> Color Balance
    • Enhance the color sliders to your preference

    The real key to this type of digital photo editing is the use of selected adjustments.  If we had not selected just the cruise ship, and instead universally adjusted the contrast on the entire photograph, then the plants would have suffered from too much contrast in getting the cruise ship right.  Of course making the sky look a deeper blue if done universally would make even the green plants start to look blue.  Therefore, the key is starting with the Quick Select Tool (W) and selecting only the area you want to adjust.

    Photography Tip - selecting and cloning a clean Ferrari 458 Italia

    in ,

    2011 Ferrari 458 Italia at a car show in St. Petersburg Florida

    • Learn this digital photograph editing technique from Jason in a 1-on-1 lesson, reserve today!

    Car shows are great places to see a large number of awesome cars in a small space.  However, that small space and numerous other car fans walking around create a nearly impossible situation for photographing the cars in full.  Detail shots are usually what I focus on, but still I want to have at least a few full car shots as well.  Some of you may know that the Ferrari 458 Italia is my current favorite car in the world.  At a recent St. Petersburg, Florida car show I had a chance to talk with the owners of the above 458 Italia who were very nice people.  I photographed their Ferrari at length.

    I could not get a shot like I wanted to while there due to other cars being parked so close to the 458 Italia and of course because of many other people coming to peek at Ferrari's latest mid-engine super car.  So I had to settle for the best angle I could get taking into account the sun's position and just the space I had to shoot in.  Photoshop CS5 helped with the rest.

    Too clone out things from complex surroundings, quick select them then clone stamp in safetyIn the above screen shot you can see how I first used the Quick Select Tool (W) to put a protective fence around the objects I wanted to remove (silver car, people, etc).  I do this because the Clone Stamp Tool (S) is very temperamental and very hard to use along a distinct edge like the front fender of the red Ferrari and the silver Ferrari.  Basically, containing the unwanted object in a quick select field allows me to not worry about coloring outside the lines, so to speak.  You can see I selected some grass from the foreground and already started stamping it onto the silver Ferrari.  The sharp edge of the red Ferrari fender will remain perfectly intact.

    Likewise for the people above the red Ferrari.  I will clone some of the trees and stamp them on top of the people to complete the illusion that the Ferrari 458 Italia is alone in a field.  To close the quick select areas hit CMD-M (on a Mac).

    Using this quick select and cloning method will allow you to cleanly and easily remove objects from complex surroundings.
