Artificial DOF - Does This Look Fake?
Back on the laptop now so here is the before and after, I modified the after to remove the graduated filter as some suggested Before: After: I also had a very quick go on Topaz lens effects, this took about 5 mins building the depth map, it would take more time to get it right cos hi...

Artificial DOF - Does This Look Fake?
But this thread isn't about how to do this optically, most of us here know how. It's about whether faking it in post is effective and how well the OP has managed his 'fake dof'... Exactly, and I think it's come off ok. As an aside, the graduated filter in lightroom works well for this, as you c...

more ff rumors part 2
I don't really need one. I want one of course. It will be interesting to see the specs. as they come out and what new features filter into the next aps-c top end camera. I believe that eventually nearly all cameras will be mirrorless.............but in the meantime.

Anyone had any experience with SRS?
Hi guys, Long story short, lent my k-500 to a friend with a 50mm for a car show. Finally got it back with a scratched to hell lens and a big gash on the sensor :( How does anyone manage to 'gash' a sensor? If there was only one lens with it there'd have been no reason to remove it. Perhaps it's ...

Anyone had any experience with SRS?
Yes, but the sensor is still covered by the filter. I wonder how he would know it was there 'before' you loaned it. He could only check immediately 'after' you loaned it to him of course. But why would he? Anyway - my mind is wandering away with me here :D Enjoy your new K3II !

Hi, am fairly new to the k3, at the moment i have the aa filter switched off what difference is it going to make for me if i use it Regards Dave

The AA filter is used in digital cameras to slightly blur the image. This means that the chance of intereference patterns (moire) being seen in fine detail is reduced. A simple example of moire is the shimmering of a herringbone jacket on a TV screen. However, many cameras are much higher resolut...

It's interesting, isn't it, that the 'AA Filter Simulator' (a function using the sensor shake technology) was introduced with the K3, the model immediately after the two K5II / K5IIs models. These offered a clear choice ... But you either had a (real) AA filter or you didn't....too late once you'd ...

The question is, how often do we get moire? When I reviewed the K-3 models I found it quite difficult to find a subject that would induce moire.

So its not a feature you would recommend specifically paying for then ? Although, interestingly, we did have to, because the K5IIs was MORE expensive ! Now perhaps the cost is very little .... ? Out of interest, we seem to have left the era of aa filters on our digital sensors (I believe both the K...

We paid more for the K-5 IIs presumably because it was a variant that was expected to have a smaller production run. No doubt it was an experiment to see how it was taken up. IIRC all the subsequent cameras where there is just the one model have the AA simulator, so the choice is built in and we ...

Certainly then its a good example of a high end feature coming into the next models down extremely quickly. As such they offer amazing value really. It's just a question of whether users would find a practical and reliable method of assessing the actual need when in the field.

Personally I see it as a gimmick, intended to offer a point of difference. I expect it to almost never be used on most cameras with the function. As John mentions the cameras are now pretty darn good, so moiré doesn't appear to be a common problem as much any more. And as Nigel points out, it's...

Thanks for the replies, so if I am taking images of deck chairs its going to be in my best interest to use it Dave

I don't think deck chairs will be a problem Dave. I presume you're thinking of the pattern in the cloth, but I suspect it will take more than that to show any moire effects.

Sometimes, I wish I could install a real AA filter on the K3. The simulator doesn't work with shutter speed above 1/1000 sec.:( P.S. Sometime, when reviewing image on the rear screen, some moire will show up because the screen resolution isn't high enough. It doesn't mean moire will show up...

P.S. Sometime, when reviewing image on the rear screen, some moire will show up because the screen resolution isn't high enough. It doesn't mean moire will show up on the picture. Exactly. And vice versa I presume. I expect you'd need to zoom to 100%, if that is an option on the rear screen? (-...
