Can a Pseudo HDR Image be as Good as the Real Thing? (Part Two)


Last week I used this bike picture to create an HDR image from three bracketed shots. The image above was created from just the 0 exposure to use as a basic single image to try out the other workflows (this one uses only Lightroom adjustments) and to compare with my own single image workflow. See Can a Pseudo HDR Image be as Good as the Real Thing? (Part One). This week I wanted to explore some of the vast number of workflows that give an HDR feel even though all are single exposure images, and try to decide – can a Pseudo HDR image really be as good as the real thing?

The top image used just a simple Lightroom preset (HDR Strong) furnished by Matt Kloskowski, one of the NAPP Photoshop Guys, that gives a pretty good place to start when just using Lightroom for the effect. It is a more realistic look, but still has that detail oriented feel HDR images present. (In this case, three Adjustment Brushes were used on the image: a Sharpen brush painted over just the bikes to bring out the edges cleanly; a Contrast brush to make the white wall in the background appear more gritty; and a Clarity brush painted on the closer posts and the sitting girl.) In Photoshop, a Curves Adjustment Layer was added along with the OnOne PhotoFrame (see my Tidbits Blog sidebar for website link) – that was it. I believe this gives a nice realistic look to what I saw but not exactly the HDR feel I wanted to.

…..

The image above used Topaz Adjust 5, one of the best and most inexpensive Photoshop plug-ins that can be bought. (See sidebar on my Tidbids Blog for website link.) That being said, I also used Topaz Detail, Topaz Simplify 3 and Nik Viveza 2 on the image. In the image below, you can see a comparison as each filter was brought into the final image. To be honest, I really liked the results even though, once again, the HDR image trumped this one for really sharp detail and color saturation.

You can see that just applying the Spicify preset in Topaz Adjust gives a pretty nice start to the pseudo HDR effect. The other plug-ins each added a little more detail and color toning. It seems logical that by trying different plug-ins together, you should be able to get some fairly good approximations to the real HDR look.

This image used OnOne’s Perfect Effects where filters are also stacked in a similar manner as Nik’s Color Efex Pro 4. The image was processed as above in Lightroom, and then taken into Photoshop where the Perfect Effects plug-in was opened. (The following filters were stacked: Photo Filter -> Blue using a custom blue color of R16G32B136 using a Strength of 39; Movie Looks -> Faux HDR; Landscapes -> Golden Hour Enhancer using the Mask Bug to target the brickwork in top of image and Opacity set to 45%; Color & Tone -> Tonal Contrast with Shadows at 52, Highlights at 92 and Clarity 13 and Strength to 50%; and Detail -> Texture Booster with Blacks at 4.) Image was sharpened and the OnOne PhotoFrame added. This gives a very strong HDR feel but the bikes do not stand out quite as nicely against the brickwork. With a little effort this image could be adjusted  to bring it more in line with the original HDR from last week.

This image gives the closest and cleanest approximation to the true realistic HDR look. It was created using three Lightroom virtual copies of the same image with the exposures sliders set for to 0, -2, and +1.37. Other settings were also adjusted to enhance individual areas of the image. (For example, the 0 exposure image was adjusted to bring out the midtones clearly. The -2 exposure was used to bring out the gritty appearance of the gray back wall and tree. The +1.37 exposure was used to lighten up some of the brick that was too dark and to enhance the silver and white on the bikes. They were all selected in Lightroom. By right clicking on one of the images, select Edit In -> Stack as Layers in Photoshop option in the menu. In Photoshop, they all appeared in one document as individual layers. Now Black Layer Masks could be added (ALT+Click on Layer Mask icon) to the top two layers. With a low opacity brush, carefully paint back in the areas you want exposed at the different levels.) It is a really great way to stretch the tones in an individual image without using any HDR software or third party plug-ins. Create a composite on top and do localized sharpening where needed. I learned this great technique from Harold Davis and am finding I use it a lot to really get great detail in my images. He calls this technique “Hand HDR” and it is described in his book The Photoshop Darkroom. He has a new book coming out Creating HDR Photos: The Complete Guide to HDR Photography that I am really forward to getting.

I created several other iterations of this image with varying amounts of success. Nik’s Color Efex Pro 4 was used following a very helpful recipe presented in a short Nik blog called My Go-To Recipe for Bringing Out Details with Ellen Anon. The single image was also taken into PhotoMatix Pro and the results were pretty good. Both of these examples had to be readjusted in Camera Raw again before I liked the results. Also processing a single image in Nik’s HDR Efex Pro gives some really interesting results although not all a true HDR effect. Several different Adjustment Layers in Photoshop can help get the color and tone in the image. Experiment to find out which ones work for you.

What an advantage to have a real HDR shot for comparison. Based on this, my conclusions on the pseudo HDR look is as follows:

  • I believe it is possible to get that HDR feel with with just one image, but, and this is a big one, how good the results obtained will be depend on the image you are trying to use. Do not expect a huge landscape with a really large dynamic range to have the detail a true HDR is going to have. If the image does not have a large light to dark range, you will probably have some pretty nice results. The image in this blog has an average range of highlights and shadows, but as seen above there is still some detail missing in all the images.
  • Saturation of the colors can easily get messed up with HDR images, much less with the pseudo imaging look. All of my examples had a real problem getting that nice brick color that my original HDR image contained.  The single images required using Camera Raw processing (sometimes twice) since it is the only filter/program in Photoshop or Lightroom that handles the orange tones. Haloing can occur with the saturation shifts and then other steps need to be taken to reduce the obvious shading.
  • Sharpening is an absolute necessity if doing pseudo HDR – otherwise it just does not have that sharp detail look a real HDR has.
  • Watch the gritty look – it occurs a lot with regular HDR images. With pseudo HDR images, it seems to be even easier to get a totally over the top look if you are not careful.

There are several resources that give some great advice. Ferrell McCollough in his book Complete Guide to High Dynamic Range Digital Photography makes a great statement. “…. the choice to shoot a single image rather than an HDR image set should be based on the contrast of the scene. A low contrast scene is easily captured and tone mapped for a single image, but a medium contrast scene can go either way in terms of quality.” RC Concepcion (one of the NAPP Photoshop Guys) has a great book, The HDR Book, that covers single image HDR processing very well and has some great tips on post-processing to get the look.

After comparing all the results, I believe that my best result was with the Harold Davis workflow – it had the sharpest edges and no halos or noise developed by the stacking of the three exposure copies. It also took the longest time to complete since several layer masks had to be created to get the final look. I still like many of the other processes though – I know I will still use my Lightroom preset from last week’s blog, and both Topaz and OnOne have the potential of creating a very good fake HDR look. But this was not just about how the different workflows create the HDR look.

The real question is – is the final result as good as a true HDR. Based on my experimentation, it is not (and to be honest I am not surprised but my curiosity made me look into this). After doing a lot of research and trying many different methods on the same picture (I am tired of this image!), I don’t think any of the results were quite as good as the original tone-mapped HDR image. You can get close, and if you did not have a true HDR image to compare to, you might think several of the single image results were good enough. But bottom line, the detail, color and tonal range is just not up to true HDR standards. I decided the image I liked best is below because it is not competing at all with the original HDR look. It was created by using the Davis Workflow image and adding Topaz Adjust to it. The Curve was changed to Negative and the Adaptive Exposure, Details, and Color sections were adjusted.  The effect was then brushed off the reading girl. I love the colors – it gives a really fantasy look and the bikes show up great!

Maybe the real question is what is HDR? Is it that over-saturated look or that super-detailed look? Or is it a totally different looking image as above that is definitely an HDR look but way out there! My advice is that if you think you want an HDR look, no matter what kind, you need to bracket and take the shots. If you take 5 images, you should be able to get a nice HDR image, even if all the shots are not great. If you could only get one shot, there are some pretty easy ways to get that HDR appearance. It may take some effort to pull the final look together, but at least you got the shot the way you wanted it!

Adding a Texture for Flair!



This week I am going to discuss textures since I suggested using them in last week’s blog on “The Soft, Dreamy Look,” which created a free action to apply to your images. Textures are a very popular effect and can give a totally nice and different look to an image if applied correctly.

Basic Technique

The basic technique involves just adding a texture image (a jpg can be added to a raw, psd or tiff file at this stage) on top of your image. Do this by dragging the texture into your photo as a Smart Object from Photoshop Bridge or just open the texture file and copy and paste the layer onto the photo. At this point I usually rasterize the layer by right-clicking on the Smart Object in the Layers Palette and select Rasterize from the menu. A Smart Object is not necessary unless you are applying a filter to the texture and may want to adjust the settings at a later date. Most texture effects are achieved by changing the layer blend modes and varying layer opacities, then using layer masks to delete out areas where the texture is too obvious. The uniqueness can come from stacking several textures using different blend modes and opacities.  There are many resources available on textures and how to use them effectively. The linked article, called “Tips for Texturing Photographs,” has several great tips – some that I want to share.

  • How do you match your image subject to a texture?  Look for subjects with a soft quality like flowers, misty images, or of simple composition.
  • Figure out what you are trying to do with your picture – fill open spaces, get a painterly look, vintage feel, or grunge look?
  • If the texture does not work, try a different one. Usually match the texture strength with the subject – soft textures for flowers, stronger textures for structures.

If using textures over photos of people, please check out this short video, “Guide to Using Textures with Photos in Photoshop  (must be a member to access now),” to adjust the tone on the people and their skin. It uses the Average Filter in Photoshop instead of layer masks.

Textures can be bought or downloaded for free

There are many beautiful textures that can be bought. Florabella Collections has two very nice sets of textures. I like the Ash Textures that I purchased several years ago, but I just figured out he is no longer selling them. This is a shame since they are really nice textures. Flypaper Textures (blog linked above to Tips for Texturing Photographs) also has some very nice textures for sale. This site also has a lot of good information on textures so take a look.  Caleb Kimbrough has released several hundred textures, some of excellent quality and most are free, at his website Lost and Taken. He has also written a really nice blog entry called “How to Create Subtle Grunge Textures” that shows how to make your own interesting textures by combining several different ones.

The top image uses a very popular effect.  It is made simply by adding a worn-looking board texture at Hard Light blend mode over a flower photo (Curves Adjustment Layer on photo gives the blown out look). This particular texture is one from BittBox, another great free texture site – this particular texture can be downloaded from the Bittbox Flickr site here – just select the size you want, right click on image, and choose Save Image As to save on your hard drive.

This image was created using a brownish Ash texture layer set to Hard Light at 75% opacity and one of Caleb Kimbrough Summer textures, which I really like, set to Overlay at 73%.


The daisy image started with my “SJ-Soft Dreamy Look Action” that I created in last weeks blog. The image can be cleaned up on a layer before applying the action since it does not require a labeled Background Layer to run. An Ash Texture was added using the Hard Light blend mode at 75% opacity, and an OnOne PhotoTools (now OnOne Perfect Effects 3.0 – website link at my Tidbits Blog sidebar) layer using the HDR Enhancer effect and HiKey Color – Cool Fade preset as a second effect layer (I am getting some nice results with its stacking capabilities). The OnOne PhotoTools effect was basically a darkening of the edges and brightening in the middle, a heavy vignetting feel. Finally an OnOne PhotoFrame was added.

Textures can be found in plug-ins

As shown in the daisies above using the OnOne PhotoTools 2.6, this plug-in has many texture options as does its sister application, OnOne’s PhotoFrame, which surprisingly has many textures that can be applied with various blend modes, just like in Photoshop’s Layers Panel.  Even plug-ins like Plugin Galaxy 2.0 have some interesting effects, such as Rain-Short Streaks, Snowflake effects, and  Color Effects section, which can add some interesting textures. You just need to play around with whatever filters or plug-ins you have and start trying different settings with them.

Once again my action was applied to the Scottish home picture which starts you off with a really nice soft look (create a composite layer or CTRL+ALT+SHIFT+E  layer on top of the action layers to apply the plug-in). An OnOne PhotoTools 2.6 Overlay Effect with the Antique Paper preset at Normal blend mode and 100% opacity was added. A similar look could probably be achieved by adding a final Color Fill Adjustment Layer using a golden tone or a Photo Filter Adjustment Layer using a warm color at a fairly high density, and a layer mask to reduce the color in the house area. That is all that was done to get this nice look.

This image does contain a brownish Ash texture, but any darkish brown texture would look good, set to Vivid Light at 38% but the painterly effect of the sky was achieved in Topaz Lens Effects – with the Graduated Color Blue1 preset applied. Then the layer was copied and set to 62% opacity to make the sky bolder.

Textures can be created within Photoshop itself

I want to show that a texture does not have to be some fancy texture that you have to buy or download – it can just be a really nice paintbrush effect on a layer that you create. Then just experiment with the blend modes, layer opacities, and layer masks to get the exact feel you want.

The above image of Scotland has a rather vintage feel to it. This was accomplished by running my SJ-Soft Dreamy Look Action and then creating a New Layer above and using Grungetract Brushes Sample #16 by alex16 at deviantArt at 2500 pixels with a light tan color. The brushed layer’s blend mode was set to Screen, the layer opacity to 66%, and a layer mask was added using a 50% opacity brush to mask out the texture in certain areas.

In the floral photo, a coral colored Mixer Brush layer was created above the other texture layer using a 300 pixel brush, and was set to Soft Light blend mode.  (See my blog “Adobe Photoshop CS5’s Mixer Brushes” for more information on the Mixer Brushes.) It can be quite addictive once you start playing around with the Mixer brushes and create some beautiful textures. I found that the by varying the size and the color of the same Mixer Brush, and actually painting with them by moving slightly, you can get really nice effects. I have included my favorite texture Mixer Brush that can be downloaded here (there area two brushes – same brush at different sizes) and added to your Tool Presets. (Put the file in the User Name -> AppData -> Roaming -> Adobe -> Adobe Photoshop CS5 -> Tools file. Restart Photoshop to add brushes to your Tool Presets – go to the top upper left corner icon under the Menu line and click on down arrow, click on right pointed arrow in upper corner to open fly out menu, and select Load SJ Mixer Brushes Presets. I usually Append the tools and they will appear at the bottom of the list. NOTE: You must have the Mixer Brush selected in the vertical Toolbar to get the Mixer Brush variations to appear in the Tool Preset drop-down.)

This is a very simple example of applying texture that can be done just using Photoshop. First two New Layers were created and the Mixer Brushes I created above were used, the small brush in beige on the bottom layer and the larger one with the same color on the top layer to create an interesting texture. A layer mask was added to the top layer to bring out the center part of the flower. Now here is the neat part, a New Layer was created and a gradient applied with the Gradient Tool . This image used Graphix1 Gradient Muted4 which is a white to yellow beige color, but try out different gradients to see what effect you like. In the Options Bar select the Radial Gradient icon and drag with your cursor from the center of the flower outward to create the gradient. Set the layer blend mode to Soft Light and add a Bevel and Emboss Layer Style (2nd icon from left at bottom of Layer Panel) and double click the Texture option.  This image used the Fractures Pattern Overlay, which is located in the Texture Fill set of patterns that come with Photoshop CS5, and set the Scale to 555% and the Depth to +34. Create a layer mask to darken the center again so the pattern is not as apparent over the center of the flower. That’s it – a texture applied that gives a really different look. Try other patterns – you can find lots of them on the internet.

And don’t forget the nice filters that come with Photoshop to create pleasing textures.  I really like the Texturizer Filter using the Canvas texture set to Relief 3 to add a painting touch to an image.

Conclusion

I have tried to show that adding texture to an image can be done in many different ways and the different techniques can be combined to get some unique looks. Once again, it is just another way the versatility of Photoshop makes it so much fun to use. It is so satisfying to create your own textures that can actually go towards creating your own artistic style. Have fun creating!…..Digital Lady Syd
