Photoshop Sign Removal

January 19th, 2010 by Maria Langer

I had to try it.

BEFORE

This photo of San Xavier Mission is somewhat marred by three signs. (The third is very small and hard to see in this size.)

While at Saturday’s San Xavier Mission shoot, I commented to the other photographers about how unsightly some of the signs on the outside of the building were. (Whenever possible, I’d actually moved portable signs before pressing the shutter release.) All of the photographers I was with at the time agreed, but one of them went on to complain that they were a pain in the neck to remove in Photoshop. When I asked whether he actually did that, he replied that he always used Photoshop to remove signs he didn’t want in his photos.

Of course, I knew this was possible and, in all honesty, I’ve done my share of Photoshop editing. Still, I was amazed that someone would go to all that trouble to remove elements photograph of a photograph in post processing.

You see, I’m a bit of a “purist.” I believe that a photograph should be created in the camera. The photographer should photograph what’s there, carefully framing the shot to create his image of what’s in front of him. Creativity comes with exposure, depth of field, composition, choice of lens, point of view. What the camera records on digital media — or film, for that matter — is the photograph. Editing beyond the removal of specks and scratches or minor adjustments to exposure or color balance is — to me at least — not photography. It’s image editing.

You could argue that a real “purist” wouldn’t edit at all. I’d have to agree with you. I didn’t say I was an absolute purist — although I’d love to be one. My photos, unfortunately, sometimes need a little help. Like most other photographers these days, I turn to Photoshop or another image editing application to get that help.

I think the difference is how much help I get from Photoshop. I draw a line before a lot of other people do. Maybe it shows — for good or bad — in my photos. I don’t know. But I’d rather get it “right” in the camera than “fix it” in Photoshop.

AFTER

After a little sign removal. The photo certainly looks cleaner, but is it a true representation of what I saw?

But after the shoot, when I went back to my camper to relax for the afternoon, I started wondering what kind of difference sign removal would make and how well I could pull it off. So starting with the photo you see above, I used the brush and clone tools to remove the three signs that were visible. You can see the end result here.

I’m not sure how this would hold up if printed as a large photo. I’m confident that the closest sign, which appeared on a stucco wall, was neatly removed. The far sign was too small to be noticeable in the first place. But that middle sign…well, who knows?

Would I do this all the time? No way. I’d rather find creative ways to keep the signs out of the shot in the first place.

The Offending Pickup Truck

October 15th, 2009 by Maria Langer

A photographer’s dilemma.

If you’ve been reading this blog for a while, you might be aware that I’ve been fooling around with panoramas. Last night, I created a panorama from 11 vertical images shot at Monument Valley:

Monument Valley Panorama

The ability of Panorama Maker 5 to stitch these together so perfectly sold me on the product. I bought it as soon as the stitched image appeared on my laptop screen so I could save my latest creation at full-size. The resulting image is a whopping 16,724 × 3,485 pixels in size and weighs in at 37MB — as a JPEG file.

Silver Pickup TruckOn close examination of the photo, however, I realized that there was one thing that marred it: a silver pickup truck dead center of the image (see red box above and blowup right). It wouldn’t be so bad, but the darn truck is shiny and really does stand out when you look at the image in full resolution.

So the question is: Do I Photoshop it out?

I experimented with this and did a reasonably good job with the cloning tool. But then I got to thinking about it. To me, a photograph represents reality. The reality of this image is that a silver pickup truck driven by what looks like a Navajo man was there when the image was shot. Removing the truck removes part of the reality of the image.

Or am I over analyzing this? Putting ethics where they don’t belong?

Are you a photographer? If so, how do you feel about modifying images to remove unsightly elements? If you’re not a photographer and just like to look at photos, how do you feel about a photographer’s honesty when creating and sharing photographic images?

Instant Tilt-Shift Faking

January 6th, 2009 by Maria Langer

Kind of takes the fun out of it.

A while back, I wrote a blog entry about my foray into the world of tilt-shift photography. Although I have no interest in investing cold, hard cash in the hardware to do real tilt-shift photography, I learned how to fake in in Photoshop by reading “Tilt Shift Photography in Photoshop Tutorial.” I was pleased with the results and found the whole thing fun and rather addictive.

Today, I stumbled upon a site that fully automates the entire process: TiltShiftMaker. You upload a photo and it applies the unfocus mask, which you can adjust. You toggle a check box to determine whether you want colors enhanced. It then spits out a photo with the effect applied, as shown below. Any idiot can do it. Even me.

TiltShiftMaker in Action

The photo I started with was an aerial shot of the Grand Coulee Dam, taken this summer when my husband and I flew down the Columbia River. There’s nothing special about this shot; I didn’t even bother to spruce it up for this experiment. So the colors are a bit washed out and the framing is far from perfect:

Grand Coulee Dam

After processing with TiltShiftMaker’s default settings, it looks like this:

Tilt-Shift Grand Coulee Dam

For a quick and dirty tilt-shift, it ain’t bad. I tried to manually modify the original image using Photoshop and my results weren’t significantly better. Sure, I had a lot more control over the amount of blur, the size of the in-focus area, and the amount of saturation to give it those punched-up colors, but when I compared my final product to the automatically generated one, I had to admit that the automatically generated one looked more like a photography of a model scene.

But it certainly does take the fun out of playing around with this technique.

To me, the real challenge of faking tilt-shift photos comes from trying to take photos that would work well as fake tilt-shift miniatures. Aerial photos are great for this, especially if they include buildings and/or cars. They can’t be straight-down images, though. They need to be shot at an angle, so there’s an obvious reason for one portion of the photo to be in focus while the other parts are not.

Anyway, if you’re interested in this sort of thing, give TiltShiftMaker try.

Faking Tilt-Shift Photography

November 29th, 2008 by Maria Langer

It works!

The other day, I got my first exposure (pun intended) to the world of tilt-shift photography. It was a link tweeted by one of my Twitter friends, @jebro, to a series of videos by Keith Loutit on Vimeo. These videos used time-lapse tilt-shift photography. The result were videos that looked as if they were created painstakingly with miniature models.

Take a minute right now and check out Keith’s video, “The North Wind Blew South.”

I’ve heard of time-lapse photography, of course. In fact, I used to play around with it using my Webcam software. You can see some examples here, here, and here.

But I’d never heard of tilt-shift photography. I did some research and found an excellent article on Wikipedia (of course) that included photos of camera equipment used to make the images. Per Wikipedia, the basic explanation is as follows:

Tilt-shift photography refers to the use of camera movements on small- and medium format cameras. In many cases, it refers to tilting the lens relative to the image plane and using a large aperture to achieve a very shallow depth of field.

The end result is that only a small portion of the image is in focus. This became popular in portrait photography. But it also has become popular as a technique to make fake miniatures — in other words, photos of full-size, real-life objects or people made to look as if they are miniature models. Wikipedia has a separate page about tilt-shift miniature faking that includes sample images.

You can also find plenty of sample images and videos on Smashing Magazine’s article, “50 Beautiful Examples Of Tilt-Shift Photography.”

Photography is one of my hobbies and I was extremely interested in this technique. I think the photos look kind of silly and cool. But I wasn’t interested in buying special lenses just to give it a try. Fortunately, I didn’t have to. The Smashing Magazine article included a link to a tutorial on the Tilt-Shift Photography Web site titled “Tilt-Shift Photography Photoshop Tutorial.” It explains how you can use Photoshop to create a fake tilt-shift photograph.

I tried it today with a number of photos that happen to be with me on my laptop. The one shown below is my fifth try. It’s a photo of Juneau, AK (I think; forgive me if I got the wrong port city), taken from an upper deck on a cruise ship. In the original photo, the entire image is in focus; for this fake miniature, I focused on a boat and two buildings in the foreground. The color is saturated and the contrast is increased as recommended to give it that painted model feel. I think this photo is a pretty good example of the tilt-shift photography effect. What do you think?

Tilt-Shift Example

My first four tries simply didn’t look right. I think it was a combination of the image I chose and the lens blur mask I used. The photo here uses a radial gradient mask rather than the reflected gradient recommended by the tutorial. That makes it possible to pinpoint the in-focus area, which worked for this image. The example image in the tutorial had a horizontal strip of the photo in focus; that simply doesn’t work for all photos.

But I apparently did get the hang of it. Here’s my next try, with another Alaska port city:

Fake Tilt-Shift Example

San Francisco in MiniatureAnd here’s a shot from last January’s visit to San Francisco. That’s the dome of City Hall with Sutro Tower in the background. I took the photo from my hotel room at the Nikko. I think it comes across pretty well as a fake miniature.

And here’s a shot my husband Mike took on a helicopter trip up the Colorado River last year. It’s the Hoover Dam with the new bridge under construction:

Hover Dam Miniature

And one more…this is the power house downstream from Lake Chelan in Washington State. It’s another aerial photo — they certainly do make good subjects for this kind of exercise. The heavy equipment looks like Tonka trucks!

Lake Chelan Pumphouse Miniature

Anyway, now that I’ve tried this with a certain amount of success, I think I can get it out of my system. If anyone out there has experimented with this kind of photography — especially using a camera and lens rather than cheating with Photoshop — please use the Comments link or form for this post to link to examples of your work. And feel free to share any tips you might have for folks who are interested in giving this a try.

More Header Images

July 9th, 2007 by Maria Langer

30 new photographs from the past year or so.

This site uses the Random Header plugin to display a random photograph from a pool of predefined photos on my hard disk. Over the past year and a half — since setting up my personal site and blog with WordPress — I’ve been adding photos from my personal collection. The vast majority of photos you see in the header were taken by me. The exceptions are the few that show me — usually in my helicopter.

I realized after my Alaska trip that I hadn’t added any photos for a long time. I spent about a half hour adding a few from that trip. It’s a bit involved because the image must be a certain size and it must have that kind of pukey color border on the left side. I’ve got it down to a science now and can whip one out in Photoshop in about 2 minutes. I also reduce the size of the photo without the border and use that for my About the Photo entries where I describe individual photos in some detail. You can see some of those images here; I’ll discribe them in

Only certain photos are suitable for the 455×200 pixel image size. For example, I can’t use most vertical (or portrait) shots, so I pretty much have to stick with landscape shots. Also, some photos just don’t crop well.

In any case, those new header images have been added to the random rotation and are already appearing online. I’ll create write-ups for some of them in the upcoming months.
