iso:1250, JPG mode, Zeiss 21

 

Never seen this before. It doesn't look exactly like a lens flair, any ideas?

 

[blakley]

It's certainly flare; you've shot directly into the sun - my guess would be that the top of the window has a beveled edge, and is refracting the sunlight into your lens, which is flaring.

 

Still, I've never seen anything exactly like this either. Mind you, I've never shot the sun at ISO 1250 with any camera....

You know it is not going to be long before someone pours tomato juice into the back of their M8 to see how image quality fares in that instance.

Of course you expect weird things shooting into the sun. However we all need to shoot into the sun or bright light source sometimes.

 

What accounts for the red to purple fringe around the windows and the red to purple halos around the lights? That looks like a pretty bad chromatic aberation to me. Maybe this is due to the use of a Zeiss lens and the M8 therefore can't perform any optimizing on it. I also see something that looks like unusual color or image below the clothing well down below the sunlight. Does sunlight flaring into the camera cause all of this? Does it happen all of the time in similar situations? E.g. how bright a light source do you need to trigger it?

1) The flare overall is likely plain old flare - the coloring could be a prismatic effect of the micro lenses, or from the window glass, or some kind of diffraction-thingy (since the sun looks to be centered right on the window edge, which might be acting as a knife-edge)

 

It also looks the saturation is fairly high (from the colors of the shaded clothes on the rack by the window) which would make the rainbow more obvious, also.

 

2) The purple edges are "blooming" or electron spill from the vastly overexposed windows and sky - which are also introducing ye olde M8 magenta bands below the sun-lit window. If it were lens CA it would be purple on one side of the window and green on the other;.

Like Andy, I tend to suspect the window here. It certainly isn't made Leica glass It looks like the same effect you get from a prism. I have seen such things on occasion with my 5D as well.

Seing this picture of ISO 1250 against the sun, I think we should open a new thread and call it.

 

"Anything a photographer would never do but still does so he can demostrate his camera is failing!"

 

Just a few ideas to start with:

 

Shot from inside a microwave oven

Underwater photography with no waterproof case

Take a piece of rope and plunge your camera into a volcano crater with lava

Do not format SD cards, it is more fun to short circuit them

....

 

by the way your post title is wrong, it is NOT "crazy rainblow flai"r but more something like:

 

"crazy photographer's rainbow flair"

How about we title it: "take a look at the crazy vertical streaking that's clearly visible across the entire image but can most clearly be seen under the clothes rack"

 

or

 

"here are some clearly visible green blobs at the bottom of the picture reflecting the windows at the top, but everyone pretends they're not there anymore, because there's supposed to be a 'fix'-thread"

 

or we could call it: "don't dare say anything negative about the M8 again, or people will start writing abusive posts about your photographic technique"

[jaapv]

This is very likely a prismatic effect from the window pane.. It would pay you to replace your windows by B&W filter glass. Btw, I get the feeling you did not use an IR filter here, as the window ledge shows some purple edges, which may well be IR chromatic aberration. That would have taken care of the green IR reflections as well.The banding is the well known thing that has been corrected on the new ones and will be fixed on the current ones.

and what's about... let's stop looking for faulty pics until we can try an updated M8? so we stop speaking about something we all know and has been described and criticized in 200 threads in this forum? but of course I am sure there is still enough room for a couple of post so you can show us purple colors on black fabrics, just in case some people are not aware of the problem.

 

Or simply consider what other readers have thought, it maybe a problem with the window glass pan and not so much the camera....

Some would say: "garbage in, garbage out" a fair physical law.

i was actually taking exception to the fact that whenever a possible problem with the camera comes up, there's an armada of people who dive in simply to abuse the photographer - as you tend to do as a general pattern.

 

Let's be accurate - your post said: "crazy photographer's rainbow flair". Other more thoughtful responses included the probably correct diagnostics of a window prism effect.

I felt that the photograph was actually a perfectly legitimate attempt to capture an atmospheric shot inside a store. You likened it to:

 

Shot from inside a microwave oven

Underwater photography with no waterproof case

Take a piece of rope and plunge your camera into a volcano crater with lava

 

Your knee-jerk abuse is as tiresome as my attempt to balance it.

[jaapv]

We can try to capture anything, but it is not guaranteed that it wil work. Sometimes we get so enthusiastic that we try to do the impossible. There are occasions that it even works, but this was not one of them. However, digital capture has gotten to a level that we expect miracles on a regular basis. Sometimes we should go back and ask ourselves how this shot would haved looked on film. I have a feeling- a lot worse. Not to get into the film vs digital argument again-talk about tiresome- but to realize the limits of our technique.

While i agree that this isn't a particularly beautiful shot (with apologies to mike), i think that a pattern has definitely developed on this forum, that anyone raising any possible new question over the outstandingly brilliant and nigh-on miraculous wonderfulness of the M8 (barring some tiresome 'bugs' that are effectively already 'fixed'), gets a heavy dose of abuse from the other members.

 

I personally don't think this shot is anything like taking a rope and plunging "your camera into a volcano crater with lava" as a matter of fact. Or even shooting from inside a microwave.

 

That sort of knee-jerk abuse is simply symptomatic of the religious fanaticism that's taken hold - often the case when a faith is under attack by fact.

[jaapv]

I agree, but it also seems to be a knee-jerk reaction to blame the camera for anything that happens. Sensor flare in this situation happens to be very well surpressed and this kind of shot is what this camera is very capable of. Sorry to repost this one, but it seems appropriate:

I see no problem in raising NEW problems. But honnestly how many posts have we read about green bulbs, rainbow things and purple colours? with this post you are just hamering on the same nail time after time again and again!. While you PERFECTLY know that Leica has come up with a solution and NO ONE seems to have the new M8 version yet to check if blending / lighting / rainbowing has been fixed.

 

So instead of coming up with NEW problems all you do is showing the same ones post after post after post etc. Who is a fanatic about showing the orginal M8 faults? why don't you wait for updated version to see if it is faulty?

 

I am not a Leica fanatic, I just think your attitude is unfair! showing things that have been shown knowing they are being fixed!!

 

Would you like to be remembers as the one who failed an exam or as the excellent professional you are today?????

 

So who is the jerk here???? me????????? sorry my crazyness sentence and easy play on word. But for the rest of my post I stand for it!

If you look at the sun refracted through a prism, you just see one colour - which changes as you move your eye. Here you have a complete spectrum.

 

I suspect the problem may be some very fine misting on the front element or filter, if there was one. You could get this sort of rainbow effect from small droplets diffracting the light.

 

Question: had you just come indoors from a cold exterior?

You only need the slightest amount of almost invisible smearing where a lens or filter has been cleaned with a cloth to produce this sort of flare.

I think it's time for your medication again.

 

oh - and btw - your signature: "let's not forget that the best pictures are always made by the photographer.... sometimes by the camara!"

Would be great if you could change that spelling to "camera" :-)

Hallo,

Look here: Interesting Leica gear

[mike prevette]

Wow, I didn't think that such a basic question would have raised such intense mudslinging. Alas it is the internet.

 

I didn't post this under the auspice of "discovering a new m8 problem" I just wanted to point out a possible quality the camera has. Knowing how the camera reacts is the only way to garunte being able to deliver exactly what I want when I need to.

 

I assure you this was an "actual photographer" making an "actual photograph". I make my living photographing things and I quite often shoot directly into the sun and other very bright things. I accept flair, and actually enjoy it when used to accentuate a scene. The antiseptic, sterile quality of some photographs are just not my thing.

 

This frame was only one out of a series of frames made from sitting in the same place, and It was the only one that exhibited this issue. So It is more than likely just my position in relation to the window glass that changed subtlety.

 

As far as any artistic intent, well I was sitting in a friends shop chatting and was struck by the glowing clothes to the frame right, and the contrast of the table to the floor. It was nothing more than a snapshot.

 

Also as to the asshatery regarding me shooting at a high iso into a sun filled shop- Why do you use tri-x? why do you use a polarizer? why do you shot velvia? why do you have your head so far up your ass?

 

It's just a choice, I like the texture, hell It was supposed to be a BW image, but I was shooting DNG's for conversion later and I thought the flare was an interesting possible quality of the camera.
