Shutter Therapy

Leave a comment

Hi all

It’s been a while since I took some photos, and as such I decided to take advantage of the blue sky and exercise my fisheye lens. As this lens distortion is most evident at straight lines, I looked for round objects. The recently rebuilt HaBima theatre in Tel-Aviv was found to be the perfect location.

As it was a sunny day, with bright buildings and dark shades I decided to use 0.7ev bracketing and later use HDR software to refine the result. I used Photomatix Essentials 3.1.1 which I purchased recently, so without any further delay, here are the photos:

and after a gentle HDR treatment:

The 2nd photo has enhanced colors, but aside of it there is no real difference between them.

Here is the front side of the building, starting from the original photo:

and the HDR, which, I think improves the visibility inside the building

and another version, which is more artisitic…

I took photos of a near by small garden, above the underground parking, here is how it looks with a regular lens

Taken with fisheye lens:

and enhanced by Photomatix

Now, let’s see the famous 3-coins statue, partially obstructing the sun (Post processed)

And last, a regular photo of a scooter 🙂

That’s all for today


Sony SLT a55 Firmware upgrade 1st results (updated)


Hi all

I decided to switch over to Blogger, mostly due to the ease of uploading photos to the web via Google+.

On this occasion I also renamed the blog: Zoom Therapy

Here is the link to the new blog:

Firmware Upgrade for A33 / A55 Models

Available beginning June 20th, a firmware update for existing α33 and α55 cameras adds several creative and operational enhancements. Support for the ‘Picture Effect’ function featured on the new α35 model is now offered. High-Speed Synch is supported during wireless operation with a compatible external flash (α55 only). Ergonomics are further improved with revised menus and a new mode that lets users switch shooting parameters overlaid on-screen for clear, uncluttered composition. The a33 and a55camera’s Digital Level Gauge can also be displayed when shooting via the optional CLM-V55 external LCD monitor. Frequently used features can now be custom-assigned to the D-RANGE button for rapid, menu-free access. The upgrade can be downloaded from: (

Photo post processing tools – comparison – part 2


Hi all

As promised (and requested) I tested the capabilities of Adobe PhotoShop CS5 and Corel PaintShop Pro 3.

Adobe CS5 is indeed one of the best SW tools, it opened quickly and easily the Sony Raw files and presented them correctly (which many tools fail to do including Picasa)

However, the current database of CS5 doesn’t support the Sony line of lenses, it supports Sigma and Tamron, but not Sony, so the only way to apply Lens Correction was manual

Corel PaintShop Pro 3 is a nice, cost effective program. It failed to open A55 Raw files correctly, also it doesn’t apply automatic lens correction.

So, as noted in the previous post, the only tool so far capable of automatically opening Sony A55 Raw files and apply lens correction for the 18-250mm is DxO Optic Pro

I suppose this is the down side of selecting Sony line of cameras and not Nikon/Canon 😦

Let’s have some fun: Fake Miniatures – part 1

Leave a comment

Hi all

I am still working on the comparison of the image post processing tools, but in the meanwhile let’s have some fun with Fake Miniatures.

What are Fake Miniatures?

Wikipedia defines it as  a process in which a photograph of a life-size location or object is made to look like a photograph of a miniature scale model. it is done by blurring the upper and lower parts of the picture, simulating a shallow depth of field. In addition the colors are enhances to create a toy like appearance

Others may call it TiltShift photography, as using tilted lens creates the same impact

I obviously took the simpler path of processing the digital image, and the number of options is large. One may do it manually by using image editing tools such as CS5, GIMP or Others may write scripts or use a dedicated plug-in. I found a very nice web based tool that automates all steps required to create a Fake Miniature, and does it quickly and in a simple manner. The tool is called TiltShift Maker, and is located in the following address: You may use it free of charge for limited output resolution, and for higher resolution you need to pay per the picture size.

here is an example of taking a rather dull photo and converting it to a more interesting one using this tool

Before: St. Thomas island in US Virgin Islands

After: the red roof buildings are kept in focus while the other regions are blurred, look at the cars, how seems to be toy cars now

Now, some homework 🙂 can you create your own Fake Miniature, either using this toll or any other and share it?

FYI, there’s a group in Flickr, dedicated to TiltShift fakes:

Photo post processing tools – comparison


Hi all

There are quite a few commercial tools for photo editing, some are free of charge, others may cost from tens of $ to several hundreds. I searched for the tool best matching my needs:

1) Ability to read Sony Raw files (.arw format)

2) Improve image quality, specifically for low light high ISO conditions

3) Ability to fix Chromatic  Aberration and Lens distortion

4) Automatic operation with minimal intervention from my side

I started by testing free of charge tools: Google’s Picasa, Microsoft Windows photo live gallery, Irfanview, Sony’s Image data converter SR, GIMP and Unfortunately Sony Raw format is not common and not supported by most of them! The only tool (obviously) that was able to open and load the Raw files was Sony’s Image data converter SR that was supplied with my camera. However this tool meets only the 1st and 2nd requirements in my list, as it doesn’t fix neither CA nor Lens distortion. GIMP and may support Sony’s Raw files through conversion tools, but it’s not intuitive.

Next I moved to the low cost tools, and the one to be tested was PTLens, obtained from This tool enables you to test 10 times before you need to purchase it for $25. It recognized my camera (Sony A55) and my lens (Sony 18-250) and was able to fix automatically the Lens Distortion. It is also possible to correct manually Vignetting, Perspective and CA, and the results look quite good. Software runs quickly and with no bugs. However – it works only on JPEG files, and doesn’t read Sony Raw files 😦

Next level are the more expensive professional tools of Adobe – Photoshop Elements 9, Bible labs 5.5.2 and DxO Optics Pro 6.5.6. All did a very good job in improving image quality, however the only one that met fully all 4 requirements was DxO Optics Pro standard edition ($169), aside of the relatively long time for initial loading of the SW I wasn’t able to find any issue. The SW identified my camera and lens, was able to read raw files and performed a nice “automatic” correction

Interim summary: Recommended SW tools

Sony’s Image data converter SR

Pros:                                                                   Cons:

Free of charge                                                      Doesn’t fix CA and Lens Distortion

Reads Raw files                                                    Doesn’t have automatic mode


Pros:                                                                    Cons:

Modest cost of $25                                                Doesn’t read Sony’s Raw files

Automatically fixes Lens Distortion                         Other parameters are manually fixed

Fixes CA, vignetting and perspective

DxO Optics Pro:

Pros:                                                                    Cons:

Works on Raw files                                                Costs $169

Automatically fixes Lens Distortion                         Other parameters are manually fixed

Fixes CA, vignetting and perspective

Improves nicely image quality

I am downloading now Corel’s PaintShop Photo Pro trial version, as it finally supports Sony A55 Raw files, so say tuned to next post…
