WHAT IS GOING ON WITH ALL THE “AI” IN PHOTOGRAPHY SOFTWARE?

This blog is a little “long-winded” but it is something I have been trying to figure out and thought I would share. For the last several weeks I have been getting totally confused by all the new Artificial Intelligence (AI) software/plugins/filters and what qualifies them as AI software. This past week Adobe’s Lightroom/ACR modules gave us a new taste of their AI capability with the Enhance Detail command. I decided to do a quick recap on a few of the AI programs. The final image above used Topaz (see sidebar at my Tidbits Blog for website link) Studio’s AI Clear and AI ReMix. I have used the new AI masking capability in On1’s very recent update and gotten good basic masking results. Also Skylum has two filters, Accent AI Filter and AI Sky Enhancer Filter which are very nice effects on images – check out article on what Skylum’s AI team is doing. Adobe Photoshop has previously used AI to upscale images in the Image Size dialog and in the Quick Select Tool’s Select Subject option and now calls their AI Adobe Sensei. Since these other filters are a little different than these I am showing, I will try to do another blog on their AI Technology. There is so much info on AI that I could create a humongous blog!

WHAT IS THE DEFINITION OF ARTIFICIAL INTELLIGENCE

I found a blog from a C-Net article with this nifty definition -“Enter artificial intelligence — specifically the neural network technology loosely based on human brains’ ability to learn from real-world data, not rigid programming instructions.” In the article Adobe senior research scientist Vlad Morariu said “Using tens of thousands of examples of known, manipulated images, we successfully trained a deep learning neural network to recognize image manipulation.” This may be what started the whole AI software evolution for photographers.

As a good example of how AI is being used effectively in photography software, Topaz Labs ReMix adjustment says on their website that they collected hundreds of classic and contemporary artistic samples; then spent hundreds of hours developing a custom neural network to identify specific artistic styles and replicating the textures, colors, edges and shapes of those styles; and finally the results were put into an adjustment for Topaz Studio. This seems to be the basic process for a lot of the AI software being developed.

LIGHTROOM/PHOTOSHOP’S ACR’S ENHANCE DETAIL VS TOPAZ AI CLEAR

Here is a screen shot of the flower shown above zoomed in to 100% to show a comparison of Lightroom/ACR’s Enhance Detail applied (for LR Develop Module right click and select and in ACR right click on the left strip and select) vs. Topaz Studio’s AI Clear, which was applied with LR as the host program. For a larger view in Flickr, click on image.

Screen Capture of DNG and Tiff file from Topaz StudioThe results to me looks like the DNG file has more texture in it but very similar sharpening – that would make sense since AI Clear has both Noise Reduction which will reduce the texture effect and Sharpening capabilities. All the settings were the same including the Details Panel sharpening and noise before applying the Enhance Detail or AI Clear. (I know, Topaz says do not do this but I do it all the time and it works just fine.) This may be a draw as far as which looks best in this case – the new LR/ACR Enhance Detail works pretty good as well as the AI Clear. But Lightroom/ACR creates a much larger DNG file while Topaz creates a Tiff. I find AI Clear probably the best product out there for subtle sharpening that is needed, especially when hand-holding your camera while shooting. Also Detail Enhance is not available in the Camera Raw filter as far as I can tell, only available when doing your original post-processing. Therefore, if you may want to get back to apply it, definitely open as a Smart Object from ACR or Edit ->Open as a Smart Object in Photoshop from LR. For the Enhance Detail command Julieanne Kost, a PS evangelist, says “I would suggest applying it on an image-by-image basis starting with images that have visible artifacts and which require the highest level of quality (images that will be printed in large format, for example).” Topaz Labs says for AI Clear use it on all kinds of images including High ISO with lots of grain, Nighttime with noisy skies, Action images with some blur, and Telephoto lens shots. My choice at this point is Topaz AI Clear – often my images are just a bit soft and this works wonders – and I can access it as a filter using Topaz Studio in PS on a layer – very easy and quick.

TOPAZ JPEG TO RAW AND TOPAZ GIGAPIXEL

Image of an Old Wooden Windmill in BelarusImage above is the final result after running this file through the various Topaz AI programs – it was from a very old IPhone and had a lot problems already. I do not believe there is an easy way to compare these two standalone packages from Topaz – they each do something that the other does not do, but there appears to be some overlap to me, like in sharpening or noise reduction. JPEG to RAW was specifically developed to take old phone (or current in some cases) and old digital camera jpg images and put them into a RAW format for better post-processing. (See my What Is Topaz’s New JPEG to RAW AI? blog.) I have always loved Topaz AI Gigapixel because it will take a really small image and enlarge it to something that looks pretty nice and detailed. (See my The Best New Software Around-Topaz A.I. Gigapixel! blog for more on it.) Below is a screen capture of how this image actually looked as the original windmill image, then after running running it through JPEG to RAW, then AI Clear adjustment in Topaz Studio, and finally AI Gigapixel (which is at half the zoom since it was doubled in size). This gives a pretty good idea of what is happening here and what basic order to use the software in. For a larger view in Flickr, click on image. The final image was finished up with some Topaz ReStyle effects (not an AI plugin but still one of my favorite Topaz plugins).

Personally I believe that Topaz is setting the standard for implementing AI use in software and it has some of the big giants scrambling. It is amazing to me to see Photoshop trying to emulate some of Topaz’s software and that can be nothing but good for us Photoshop users. The AI technology seems to be breaking open right now and I can hardly wait to see what is coming next! Okay – I am done!!! Hope everyone has a great one!……Digital Lady Syd

WHAT IS TOPAZ’S NEW JPEG TO RAW AI?

Image of some pink daisiesI am with most of you – say what?????? I knew Topaz (see my Tidbits Blog for website link) was working on some new software for JPG’s but this one is a real surprise. I have been working with the stand alone program for a couple of weeks, but it has taken a while for its wonderful capabilities to sink into my head. So this is what is going on…..it is somewhat similar to AI Gigapixel which I totally love and AI Clear which I can’t live without. (See my The Best New Software Around – Topaz A.I. Gigapixel! blog.) JPEG to Raw AI (J2r) uses similar machine learning technology to recover lost detail in jpg files and convert them to a dng or tiff extension. This will open up the Raw Converter in Photoshop or gives better slider capabilities in Lightroom.

There is not a lot of info released on this software yet so their website seems to be the best resource to find out more info and where a trial version can be downloaded. Below is a rundown of what Topaz is saying about their product.

Why Use this Program?

  • Topaz states “There’s also enhanced dynamic ranges as shown by deeper shadows and enhanced highlights.” This is important and to me and is the best way to see results from applying the software. The program basically helps clean up jpg issues from smart phones, especially from some of the earlier versions, and older digital camera shots that just created jpg images.
  • J2r uses the ProPhoto RGB Color Space that Lightroom uses. Most jpg files contain the sRGB color space which has very limited color choices. With the ProPhoto color space there will be better saturation and vibrance without any visible artifacting in your image.
  • When an image is run through the program, it goes from 8-bit mode to 16-bit mode. This removes banding and converts the image from 72 dpi to 300 dpi, which usually results in a more normal sized file. I personally really like this. I hate opening up Image Size in PS to find out my image is at 72 bit resolution and 72 inches tall! Also, changing the resolution and downsizing in PS can be tricky.
  • Artifacts in some jpgs can ruin an image and can be accentuated by post-processing, especially when sharpening. Topaz says “This program will remove these artifacts while preserving natural image features.”

The image above is one of my recent phone shots taken at a local Lowe’s Garden Shop using an older Android phone. Below is a before close-up of the  original out-of-phone jpg on the left and the converted to a dng file on the right. It is a very subtle adjustment, but look carefully at the lower green leaves to see more detail in the shadow areas of the dng file and a little more definition in the bright areas of the lower right petals. Even the yellow centers seem a bit more defined. In PS Topaz Studio’s AI Clear Adjustment was applied (I use it on just about every image). The final post-processing for the image above used a clean up layer, a little fine line dodging and burning (see my The Best Dodging and Burning Technique! blog using John Paul Caponigro’s technique), a Curves Adjustment Layer, and a painted in vignette.Comparison of JPG vs DNG

I have had a bit of a problem figuring out why some of my images improve when run through the program and some not so much. One of the engineers explained in their presentation:  “While it will remove noise/blur and recover some detail, you’ll see most of the benefits when you try to edit the photo. Viewing a well-exposed high-quality JPEG before and after running it through J2r may not show a huge difference, but your editing capacity for that same image will generally go up.” After working with the program quite a bit, I believe this is very true. Since I use PS more creatively, I may not notice color shifts or tone changes as readily as many photographers who are looking to improve many of their less desirable images. Below is another example of what this software will do – this time a Casio QV-2900UX, a 2.1 Megapixel camera with a 8X zoom creating only jpg images, was selected. I was pretty impressed with the results – the image on the right is the original jpg file, the middle is the image after running through AI Gigapixel, it is still a jpg file, and on the left is the dng file. It definitely has a lot more detail – I thought it was a little crunchy for my taste but then realized it was little flowers showing up. Who knew they were there? On the sky to mountain line, there was some fringing going on after AI Gigapixel was applied.
Comparison image of the three programsFor the final image below, the fringing was removed by just painting on a new layer over with a small sized Clone Stamp. There was no fringing anywhere else on the image. A gradient map was added with blue and cream tones set to Soft Light blend mode at 71% opacity, a spotlight effect on a few of bright areas of the telescope domes, and Topaz Studio’s AI Clear at default settings. Overall the image turned out really nice and so much better than when I first post processed it back in 2004. We’ve come a long way!Image of telescopes at Kitt Peak, Arizona

What is the Difference between AI Gigapixel, AI Clear and JPEG to RAW AI?

Here is a quote from Celeste during the software release of their new product and pretty much sums up what Topaz is doing here. “While each of these products uses Artificial Intelligence to improve the quality of your photos, there are a few distinct differences. Gigapixel uses AI to enlarge your photos while preserving detail for printing. AI Clear uses AI to reduce noise and sharpen. JPEG to RAW uses AI for a variety of different purposes – it does reduce noise and sharpen, yes, but it also helps to restore details lost in a compressed JPEG, enhances shadows and highlights that are lost in a JPEG file, prevents banding, and reduces blockiness. There are distinct disadvantages to a JPEG file, and the AI for JPEG to RAW was specifically trained to restore the things that were lost when the JPEG was compressed. While they all have their advantages, JPEG to RAW is going to be the best for improving your compressed JPEG file!”

Below is a screen capture image using Snip It that is from the Old Faithful web cam in Yellowstone National Park on January 31st in the early morning- I had never seen bison in the cam camera before and it looked spectacular! There appears to another geyser erupting in the background and Old Faithful was spewing pretty steadily so there was a lot of mist in the air. The screen shot was run through JPEG to RAW first to create a dng file (_edit is added to the end of the file name so you know this program was used). A Tiff file should have been selected, but I was not sure what I was doing. Then I ran it through AI Gigapixel set to 4 times creating a Tiff – Gigapixel puts the _output suffix on the file name.

Bison grazing at Yellowstone National ParkI will tell you what else I did but it is not pertinent to the new program so skip this paragraph if not interested. Next PS was used to open the image and ACR opened up where some changes were made. No sharpening was done at this point. Then it was opened as a Smart Object in PS and cropped. Lucis Pro was used to sharpen the bison – black mask and just the bison painted back. I imagine I could have added the sharpening in ACR. A Color Look Up table was applied – one I created to just create a sketch effect. Now the real magic came with using Topaz Studio – AI Clear (set to defaults and Exposure -0.08, and Clarity 0.48). Next the Edges Adjustment was used – this can really sharpen up an image and worked great on the bison (Edge Tone Dark, Edge Strength 0.15, Suppress Weak Edges 0.21, Suppress Small Edge 0.02, Edge Thickness 0.16, and Edge Resolution 1.00).  Precision Detail Adjustment was added (Overall Small Detail 0.30, Overall Medium Detail 0.43, and Overall Large Detail 0.36-used a Gradient Mask set in middle of the image so sky was not affected, just the middle ground and foreground); and Impression Adjustment used the default settings (set Number of Strokes to High, Stroke Color Variation set to 0.25 and Spill 0.32). To recreate a better mist effect, on a separate layer a fog brush was used to fill in where the screen shot lacked mist and several Grut Cloud brushes (the best around by far) were used to enhance this soft effect.

Okay, here is the original so you can see what a difference this made – all three programs – J2r, AI Gigapixel, and Topaz Studio – helped create the above.Original image of Yellowstone

Bottom Line

This is definitely a program that you should try out. Be prepared to have a bit of a wait if processing a large jpg through the program. It is not as fast as Gigapixel. I do believe that I am seeing some changes, even though they may be subtle, and I know that Topaz will be adding capabilities to the programming so it will be even better in the future. (Don’t forget, if you buy it, all updates are free forever!) They are definitely the cutting edge leaders in AI technology for photography and they have not let us down yet. So I will be trying out more images with the program and plan to write more as I learn. In the meantime, try out the 30-day trial on some of your images and see what you think. And let the Topaz team know if there are having problems, they are always very interested in knowing about them. In the meantime hope everyone is thawing out after this horrible cold spell that came through the US. Have a good week!…..Digital Lady Syd
