Today (30th April) Adobe released Photoshop CS5 Trial. I grabbed copy early and wanted to try the new features. here is a quick take on HDR Pro feature of Photoshop CS5.

Among all the new features CS5 boasts HDR Pro is one of the most hyped. Till now we needed to go to 3rd party soft wares like Photomatix Pro to get that HDR look we want. This feature is revamped-from-the-ground-up and called HDR Pro. Like the Merge to HDR feature in Photoshop CS4 and earlier, HDR Pro lets you combine two or more exposures of a single scene into an impossibly rendered composite, complete with wide-open shadows and richly detailed highlights. The big difference: Unlike Merge to HDR, which is about as easy to control. HDR Pro offers superb controls and delivers quite a reliable result.

I quickly compared my Photomatix pro rendered HDR which features in my last blog Nir-Laksha Dweepa-Day2-Kalpeni. I used the same set of files and here is the result with HDR Pro. I think there is definite improvement from the CS4 version. But if you want superior control over your HDR then photomatix is still the king. Let us see the results. First is rendered with Photomatix pro and the second using HDR pro. Judge yourself which one you prefer. As you can manipulate any HDR to your hearts content, there is definitely scope for improvement in both the shots. This is what I liked.

Remove Ghosts option is new in HDR Pro. This will eliminate movements when you are shooting multiple images in a busy environment. I had a photograph of Tilakkam island from that trip which I had taken as HDR but was unable to publish as there was ghosting artifact I thought that would be perfect candidate for checking ghosting option and predictably it came out picture perfect with HDR Pro. Here are the results. First one is with Photomatix Pro which produced nice output but with lot of ghosting artifact which is minute but visible on large photo.

Here the same set of photos by HDR Pro which ghost elimination has made it crisper. Even though I like the output Photomatix produces HDR pro is winner here.

Remember that this is not a definitive review or a shootout between this two HDR softwares. It is just a short comparison I did within the short time I had to express my views. I welcome your view on that.

Macro Stitching a Moth - Final Result

This panorama of Oleander Hawk-moth is by using 5 macro photos. In this tutorial I will use Adobe Photoshop CS4 which has greatly improved panorama tools, to produce this macro panorama. This version makes stitching odd photos so much easier than any other program I know of. If you notice these photos are not sequential like the normal pano shots we take. I took this way just to check the capability of Adobe Photoshop CS4 in identifying various segments. You will notice first two shots are of right and left wing, then three shots are of the body from top to bottom. This sort of mixed arrangement stumped most stitching applications out there.

My earlier favorite was PTGUI. When I tried it with these photos it failed miserably to recognize control points. The resulting panorama was a horrible mess. Adobe Photoshop CS4 excels in the aspect of recognition of various segments in the photos.

I was trying to photograph without tripod that day. My Canon EF 100mm f/2.8 USM Macro was not able to get the full moth at 1:1 magnification. I used 20mm Kenko extension tube along with 100 mm and photographed the moth in 5 pieces with the intention of stitching together later.

I had to make sure that background was as clutter less as possible. This was easy as it was quite dark outside and I was using my Canon MT-24EX macro twin light flash so that background would be dark.

Next thing I wanted to make sure that there will be at least 20% overlap of parts in each photo, otherwise Photoshop will find it difficult to stitch them together.

Macro Stiching a Moth - Select Files

Once I imported the photos to Adobe Lightroom I selected these 5 shots and chose Edit in Photoshop as panorama.

Macro Stitching a Moth - Send to Photoshop

After churning out a bit, Photoshop CS4 produced this beautiful image of the Oleander moth all stitched together.

Macro Stitching a Moth - Panorama on Photoshop

I flattened all the layers and filled the transparent area with black around the moth. I also cropped and rotated to get this final result in Photoshop. So what we have at the end is around 100 mega pixel image of moth which is perfectly stitched and exposure blended. You can see this image at the beginning of this post.

If only I had tripod handy that day, I would have used macro focusing rail and could have taken several shots using canon MP-E 65mm 1x-5x macro and produced 1000 mega pixel monster photo ha ha, I was just joking

Anyway it was fun to try this panorama like stitching using macro that too with shots which were hand held. Photoshop CS4 has really improved its method of Photomerge and produces seamless stitching with excellent results. I hope this small tutorial helps many macro shooters out there who find their subject too big to fit in one frame

Focus Stacking Using CombineZ

After trying out the Auto-Blending in Photoshop CS4 I wanted to compare this method with my other favorite focus stacking software CombineZ. There are quite a few tutorials out there on usage of the CombineZ. I highly recommend the great tutorial from Brian at Digital grin. Brian is one of the greatest Macro specialist I have seen. he as also a great teacher you can check his work at http://www.flickr.com/photos/lordv/ & http://www.lordv.smugmug.com

I tried the same set of files which were used for the Auto-Blending in Photoshop CS4 Tutorial. The result was far better with CombineZ. Also the alignment of the various layers was perfect in CombineZ, which in CS4 you need to run auto-align layers separately.

Then I tried manual hand stacking in CombineZ as well as CS4. This is a method which is well explained in CombineZ help file is useful when softwares find difficult to align several layers. CS4 does not provide any such method. If auto-blending is unsuccessful by cs4 there is very little you can do as the masks which are produced by CS4 are quite complicated. Here CombineZ wind hands down.

To conclude CS4 auto-blending is easy and quite fast, where as CombineZ produces far better result. CombineZ also allows manual stacking and to top it all it is free.

The beetle you see with this picture is the same set as my Auto-Blending in Photoshop CS4 Tutorial. Here I have used CombineZ to stack photos compare the photo with the one I posted here
