Interesting panning blur...?

[DamienB]

Spotted on another forum...

This shot taken at 1/750 according to the EXIF:

Impressive amount of panning blur for that shutter speed, no?

And this one taken at 1/500:

I have to admit I'm curious as to the obvious discrepancy here.

I don't see any exif data available. If you mean you saved the photo and checked it out, I wouldn't necessarily trust it since it has gone through processes on this site...

[DamienB]

Install the IEXIF plugin for your browser and you'll see both shots do have EXIF data.

Two possible factors: different approach speeds and different focal length. DId anybody ask the photographer? I have seen weird accusations of armchair photographers in the past...

[DamienB]

I'm not an armchair photographer; I do agree with you there are some silly accusations, but in 15 years of photography I've never seen blur of that extent with a shutter speed that high. My email to the photographer is being 'reviewed' before going to him apparently.

The the focal length is between 100 and 200mm on both shots, insufficiently different to explain the huge blur in such a fast shot, and the speed of the subject isn't going to vary that much either (A-10 take off versus airliner approach?).

Set your camera to 1/750 and a focal length between 100 and 200 and have a play - see if you can get that sort of panning blur without falling over...!

I didn't accuse you to be an armchair photographer, but I have seen quite a few weird accusations on other forums so far.

Again: did anybody ask the photog already on that forum?

email sent!

I'm curious to the photog's response. I don't believe that much motion blur is possible at that (alleged) shutter speed. I would expect the actual shutter speed to be well below 1/200.

You may understand, that we won't post his reply here. If the reply is not satisfactory, the photo will be deleted, that's all you will see.

So, what are we saying here? That the picture is photoshopped in some way? That the EXIF data may be wrong? Or something else?

In my humble opinion the picture looks fine, well taken and the motion blur ok. Of course, I am not an expert in these things. I certainly wouldn't have thought to check the EXIF data to see if the information matched what I could see.

But I am concerned that the whole thing was made public. This is something that the screeners, the photographer and the person bringing the concerns should discuss in private. It is not something to be splashed around the forums in my view.

I am just curious if PS is capable of adding motion blur? I know PS is extremely powerful.

The only extreme manipulation i have ever thought of doing was to "blend" two images taken together (One over exposed and one under exposed). But that seemed like too much work so i gave up on the idea. I'd rather let the camera do all the hard work .

I prefer to think maybe the EXIF data was wrong but someone with PS talent could do the same. In layers you could blur the background horizontally then paste the plane on top of it.

Just to add my 2c worth to this thread:

a) Yes you definitely can create background motion blur effects in Photoshop. You need to be a dab hand at cutting complex shapes out (like with magentic lassoo or similar) but it can be done.

b) Re shutter speeds, for comparison sake this is sitting in the queue but was taken at 1/80 at a 150mm focal length:

You can do anything in PS. I have done motion blur, made aircraft flying when they clearly were not and make it real (except I forgot the elevator!!!) and also the mirror effect on the ground (when there is a puddle) It all depends on how much time you want to waste on a shot and how much your willing to play around with the shot.

Damien I don't see the point of this thread at all....You emailed the photog, no need to make a post. You’re raising a question to the person's integrity and this is not the place for that.
