Panasonic GH2 Raw hot spots/dead pixels trouble

Hi,
Like explaining in this link , I have bright green spots on my picture in Lightroom.
My old camera Panasonic G1 didn't have this problem.
How these spots is removed by Adobe raw processing ?
Is it a problem with the raw file from my camera (something wrong or missing inside) or a problem with Adobe raw processing for this file ?

Hi,
As this is a User forum, Adobe are not guaranteed to see this post (although they DO look through from time to time).
I suggest you raise this with Adobe directly, submitting a bug report for at the following address;

Panasonic gh2 raw now subtle pink?

So the recent update has fixed the obvious vivid green darkening of gh2 raw files. Hurrah!
Except that the images, whilst vastly improved, now have a slight pink cast compared to the in-camera jpegs and to files developed into tiffs using the Silkypix program supplied with the camera. And initial views suggest that the Silkypix images are generally superior - both sharper and less noisy - although I haven't spent time fine tuning the raw settings in Aperture yet. Of course, having to use Silkypix is annoying as it wastes time and disc space and I lose all my image metadata.
Before sending a bug report I thought I would ask if anyone else is experiencing this problem or if they feel that their gh2 raw images are now acceptable. It would be great to hear from anyone who has both aperture & adobe raw and can make a comparison between their processing.

Same problem with the latest RAW update (3.6). Instead of being greenish now it's reddish.
The treatment of Panasonic GH2's RAW file is not good as it should. Unfortunately, I will have to continue to use SilkyPix to deal with RW2 RAW files instead of Aperture.
Apple need to work a little bit more to fix the problem

Panasonic GH2 RAW files go deep green with latest update

I updated my machine yesterday for the RAW updates. There is an issue here as far as I can tell with the Panasonic GH2 precessing. GH2 RAW files thumbnails look fine but Aperture, iPhoto and Preview all show a dark deep green image. Silkypix shows the correct image from the same file.
Is anyone else seeing this?

Same issue here. Have posted to Aperture feedback and included a link to an example. I was shooting raw + jpeg until the camera became supported, so it's very blatant the raw processing isn't working. I tried using a range of camera settings to see if some of the intelligent DR features were tripping it up, but always the same result, even with all the advanced features all turned off.
What would be interesting is to hear if anyone is NOT experiencing this problem with GH2 raws.
Here's a link to the sample:

Dead Pixels/Dark spot?

I was just working on some homework on my macbook pro and all the sudden I noticed this dark spot/dead pixel in the right center of my screen. At first I thought my screen just got dirty, but that was not the case. Can anyone tell me what this is... and if apple will cover this?

****... well here is the weird thing... there hasn't been any sort of blunt force or anything even close to that, that happened to my laptop. I make sure that if I ever take it out that it is gentally set down. I have the laptop sleeve as well as a laptop bag.
The only thing I can think of is that maybe when I sent my Macbook Pro into Apple to get the logic board replaced that somehow some sort of pressure was applied to the screen to cause this. Would the problem that I'm having appear several days/weeks/months after the actual day when some sort of pressure is applied to the screen? I think this whole dead pixel or whatever it is happened sometime within the past 3-4 days in which my laptop has been sitting here on my desk with nothing stacked on top of it.

Hot / dead pixel elimination in later versions of Camera RAW

Hi!
I was wondering if we could get some under the hood info on how Camera RAW handles hot / dead pixels. The standard answer 'Camera RAW eliminates these automatically' does not apply I'm afraid. I've seen more and more of these stuck pixels in my final output over the last few CR versions. Now, it could be my camera showing its age, but I'd like to know more about how Camera RAW maps stuck pixels.
I've just re-developed a set of some stage performance from last year, Canon 5D Mark II, high ISO and pushed, yes, but thats my whole niche. There's stuck pixels in all of them in the same spots. So I wondered how camera raw handles the whole mapping / processing of hot pixels. The set of images are here, and there's access to full size images also: http://www.flickr.com/photos/mvejerslev/sets/72157627732199199/ (I did clone out the stuck pixels on just a few of them though). It's a mix of processing version 2010 and 2012. Did not make a difference to the stuck pixels.

Well, the issue with higher ISO images is: what's a hot pixel vs. what's a result of salt & pepper noise–those are different artifacts...
When you start ramping up the ISO (and use PV 2010 or 2012 without luminance noise reduction) the likelyhood of random bright (more or less) pixels (or subgroups of pixels) goes up.
The hot pixel fix is still in LR/ACR...but it becomes a battle between what's a hot pixel vs what's a result of camera noise...and ACR/LR tend to be very conservative when it comes to mapping out a hot pixel (or dead or constantly a certain color pixel).
ACR/LR can really only estimate what constitutes a hot pixel because there's no way of recording the XY position of a single pixel and telling it how to handle the mapping. It's an auto thing and as such it's subject to sometimes not working perfectly...
To really determine the issue, one (or Eric) would need an actual raw file–not something that's already been processed and resample. The more examples of ACR/LR not doing an optimal result the better the likelyhood somebody will look at doing something about it.

Dead pixel surrounded by white spots

I have had my Powerbook G4 for about 3 months and have noticed a dead black pixel in the lower, center portion of the screen. I believe this deadpixel is abnormal because a cluster of white light surrounds it making the area appear larger than just the dead pixel (the white cluster is most apparent under greens, blues, dark colours). The white spot surrounding the dead pixel appears to be increasing in intensity and size.
Does anyone familiar with this problem? Could the dead pixel be affecting the pixels surrounding it? Will Apple replace my screen?
Denise.

Hi Denise & Welcome to Apple Discussions --
Take a look at the following Apple Kbase article, if you haven't already: http://docs.info.apple.com/article.html?artnum=22194
You also might find this web page to be of interest: http://forum.notebookreview.com/showthread.php?t=11976
Sometimes, you can get rid of dead pixels by very, very gently massaging the are of the dead pixel with your thumb -- this doesn't always work, of course and you need to rub very, very gently.
Bottom line: if you're unhappy with how the screen looks because of the dead pixel(s), you need to take it in to have Apple look at it to determine what can be done. No one on here can make that call or can accurately predict what Apple will say.
Good luck.

PS You may have heard that some PowerBooks suffered from a known problem of faint white spots in the display, see http://docs.info.apple.com/article.html?artnum=86632 But, as you can see, this issue was with PowerBooks produced a while back (and at least 2 or 3 revisions ago, and to the best of my knowledge the problem has been resolved.

Dark spot (not sure if it is a dead pixel).

I have a dark spot in my menu bar. I'm not sure if it is a dead pixel... it almost look like if there is dust inside my screen. Do you have something to recommend to take it away?

If you have not already solved your monitors problem, you can try PiXel Check, to see if you have any dead or stuck pixels.

Dead pixel spot

I just bought an iPod Nano a week ago.
I imported all the CD's I had into iTunes, and when I connected the iPod to the computer (Windows XP), a black spot the size of a laser pointer appeared.
I went back to the Apple store from where I made the purchase, but they told me that this happened because water got inside, and they could not help me.
I only took the iPod out of the case when I connected it to the computer, and it did not come in contact with water.
Could someone help? It was supposed to be a birthday present.

Sounds like you've got dead pixels. Just call support, and tell them your situation. They generally won't replace anything for 1 dead pixel, but for a spot the size of a laser pointer, they should. Especially with the size of the nano's screen. Also, the water(possibly) could have gotten in during shipping. Just tell the support guys everything.

Slightly ligher spots on black screen? NOT dead pixels...

This is my 3rd MB after a series of exchanges for other problems. So far this thing is flawless.
However, I noticed that on a BLACK screen, there are two small oval-shaped sections near the center that appear SLIGHTLY lighter than the rest of the screen. It is really only noticeable when the entire screen is black. The areas simply look like there is a finger print on the screen, but us BEHIND the plastic. I tried using a microfiber towel to clean the area and it is not externally.
I know I'm being picky, and the spots are not visible at all on any other colors and looks smooth; it is only on a black screen.
I really dont feel like taking this in a 3rd time (for a 4th computer). Should I just live with it? It's still better than the other previous MB's as far as issues. My only worry is that my exchanged computer or screen will have a dead pixel, which would be worse than this honestly.
Your thoughts? Is this normal? Is some color discrepancy normal on pure black colors? Thanks!

I think everything has flaws; it's just whether or not they're visible. The irony is you could have one that has one or two cosmetic defects and it lasts you 10+ years; however, could have one that is cosmetically perfect, but go through two or three logic boards in its lifetime. Anything is possible.
I can't say that you are or are not having problems that are "normal" b/c computers are almost synonimous w/ cars these days as far as defects, warranties, and repairs.
My first blackBook had a slight bulge in the bezel, next to the isight--took it back to Apple three days later, they exchanged it no problems. The new Blackbook they replaced it with had a bad Return key (the scissor was broken). They replaced they key, no problems so far and I'm very happy w/ it. I have AppleCare not b/c Apple would tell me to buy it, but b/c I plan on keeping the computer for 3 years at minimum and don't want to deal w/ repair cost (if any).

Dead pixel - worth the trouble to exchange?

Will Apple give me a new iPhone since mine has a dead pixel, or is it not worth it to try?
iMac Core Duo, eMac G4 Mac OS X (10.4.10) And an 8GB iPhone!

Can someone explain this to me? I have what appeared to me to be about 20 dead pixels on my screen. I took it to genius bar and they said I only had 3 and this was normal and that everything else I saw was natural "bleeding" that would "go away in time." The dead ones and the "bleeding" ones look exactly the same to me. Now I'm reading here that people have just one dead pixel and apple is honoring their exchange? Why not me? I have what looks like 20!

Power down your Jetpack while it is not in use, at least until you get your usage problem under control. Bring your PC to a different area and see if you can let it sit connected for a while to complete whatever it is struggling with.

Having trouble using hot spot on my Lenovo Windows 8

I have called tech support at verizon. I was able to use my hot spot with my new computer a couple of times but now it does not recognize my hot spot. Are there any good solutions out there?

Never mind - it turns out that just installing synaptics fixed everything :-)

Ipad hot spot connection trouble

I connect my ipad to the internet via a hot spot on my iphone. Worked perfectly for months and suddenly it won't connect. My phone says there is 1 connection and ipad says connected but the ipad never shows a check beside the iphone hotspot. Any suggestions?
Thanks!

If the hotspot you are trying to connect to is a "captive portal" type of hotspot, which are commonly found in public locations, such as hotels, airports, cafes, etc. If you are connecting to this type of public hotspot, you may be required to complete an additional step before you will be allowed to access the internet. This may be to login/register for an account, acknowledge terms of acceptable use, pay for access time (if its not a free hotspot), or some other similar action. If this is the case, you will be redirected to a login page in your browser after you connect to the WiFi network using the steps that @Weth listed above.

[Solved] Dead Pixels GE70

Would like to know if warranty covers dead pixels? I have one blue dot on my GE70 screen. Laptop is still quite new.

Quote from: Syrellaris;111265
Well first you need to know what pixels are. You got 3 different types. Stuck, dead, and hot pixels.
A dead pixel is always off, there easy to spot against a white background.
A hot pixel is always on. They are mainly very bright white pixels and are easy to spot against dark backgrounds.
A stuck pixel is mainly blue, yellow, green or red but sometimes a light dark.
Stuck pixels can be fixed most of the time. There's several ways to do this.
1) use a program that quickly flashes different backgrounds in various colors. Try using jscreenfix or something similar. (sometime it can take a few hours of continuous flashing the screen)
2) rub it uusing a stylish and a damp paper towel, apply a gentle pressure over the effected area.
3) tap it. Cover something up and rapidly tap the pixel.
(option 2 and 3 can have obvious risks, so be careful)
Thanks for the suggestion mate! My pixel is blue so it's probably a stuck pixel. Gonna try your suggestions after this.

How can I use my iPhone'hot spot to send email from my computer ?

Hi,
My land line is dead ... so no phone nor internet at home. But I can use my iPhone'hot spot to get on the web from my iMac. Great ... it works !
Oups ! I cannot send email from my computer using my iPhone's hot spot with Mail.
How do I do that ?
Regards.

Hi iCare,
Thanks for helping ... All that configuration is already done. I am able to surf the web from my computer using my iPhone's hotspot.
When I want to send an email from my computer, I get a message asking me to select the the SMTP server. Then I select my usual ISP server, but the message comes back telling me it does not work.
Is there any other configuration to do ?
