Hot Pixel Test - PLEASE HELP with results!

[brian_calif]

I did the Starzan Dead/Hot pixel test for my new Canon EOS 20D with 18-55 lens cap on in a dark room. Noise Reduction = Off, Mode = M, Set to MF. No Dead Pixels (using default setting of 250). I have hot pixels (using setting of 40).

Here is the Hot Pixel list:

I have one day to take the camera back and exchange it. What do you guys think? Do I have a bad camera?

BTW...thank you all for the guidance on how to do this!.

Also is there a way to print out a test report using Starzan?

THANK YOU!!!

 

[brian_calif]

Can someone give me a critique my Hot pixel test results (below).

I need to return it early tomorrow. Just wanted some thoughts from those in the know.

THANKS!!!

You can exchange it at best buy, but you won't get much better than what you have. In fact there is a good chance you will do much worse. The hot pixel test is generally done at the default setting of 60. Why did you choose 40?

Chet,

I read many other threads here and many said to rerun it at 40 instead of 60.

I reran it at 60 as you suggested and here are the hot pixels...

ISO100 (1 at 8 seconds, 2 at 30 seconds).

ISO200 (1 at 4 sec, 1 at 8 sec, 2 at 15 sec, 5 at 30 sec)

ISO400 (1 at 2 sec, 2 at 4 sec, 3 at 8 sec, 7 at 15 sec, 20 at 30 sec)

ISO800 (2 at 1 sec, 1 at 2 sec, 2 at 4 sec, 5 at 8 sec, 18 at 15 sec, 37 at 30 sec.

ISO1600 (11 at 1 sec, 4 at 2 sec, 5 at 4 sec, 20 at 8 sec, 20 at 8 sec, 44 at 15 sec, 77 at 30 sec.)

THIS STILL SEEMS TO HIGH FOR ME. ANY FINAL RECOMMENDATIONS FOR ME?

I really think that you are well within the limits of having a good camera. You certainly have the option of exchanging it, but I would be willing to bet you would not get a better one. If you shoot in raw, and convert to tiff using photoshop cs you will find it automatically removes most of the hot pixels. DPP and EVU do not do this. In fact, DPP usually shows one or more hot ones than does EVU. The ultimate test is to take a picture and see if you can actually see a hot pixel. You can view them in the dead pixel test program, but when you do a 100% enlargement they are generally very hard to find. Best buy usually has a demo camera. Take your card to the store and take some pictures with the lens cap on (and regardless of what some say, with the viewfinder shielded) and go home and run the test. Also, make sure the camera is in a dark place because light will definitely leak in around the lens cap and interfere with the pixel test. Set the camera in manual focus and manual mode and close the lens down to f22 or whatever the smallest is. I have what I consider a good camera, and at the moment I can't find the paper I wrote my results on. When I do I will show you what mine did, but it is very close to your results. Many people are publishing their results here, but no one seems to be doing it the same way. Also, if they have converted from raw using photoshop, the results are completely incorrect.

I read many other threads here and many said to rerun it at 40
instead of 60.

I reran it at 60 as you suggested and here are the hot pixels...

ISO100 (1 at 8 seconds, 2 at 30 seconds).

Hi Chet, remember me? I couldn't get my images onto my PC? I was given an exchange after the Canon UK Techie who talked me through the procedure over the 'phone couldn't get my PC to recognise RAW. I'm very pleased now with the new 20D although the card reader still cannot be used. Thank you for your help!

Sure, Katy, I do.

I was thinking only earlier today about you and your problem and wondered what happened. I was going to do a search for the previous thread to see if it had been resolved. Can you now get the raw images from the camera using EVU or DPP? Did exchanging the camera solve this problem?

Yes, I love using DPP, and EVU recognised my RAW images. BUT, I was so used to my card reader and it was so simple, now I have to DRAG and DROP every single image into a folder! It's very time consuming, but it's worth it because the 20D is certainly an UP GRADE from the 10D,

all the best Katy

Don't know how to do that. Please tell me how,

[Chester Cox]

When you are in EVU or DPP, click on a picture you want. Hold down the control key (Ctrl) and click on all the rest of the ones you want. Then drag the whole mess to the folder you wish to place them in. I believe this is what the prior post is referring to. There are other ways to select, but this is probably the best to selectively choose the ones to place in your folder. I still do not understand why your card reader will not function properly. I know you are using windows xp. Do you have any of the service packs installed (sp1 or sp2). Also, can you click on control panel, open up the 'system' icon, select the 'hardware' tab, select 'device manager' and tell me if you have anything with a yellow thingy in front of it (now there is a descriptive word). I don't have any so I don't remember if it looks like a question mark or possibly an exclamation mark. Let me know what you find.

Well at least you have no yellow thingys. Just for fun you can try the same procedure by using evu and clicking on your folder that contains some pictures without the camera. Select a bunch of them using the procedure outlined and simply put them in another place of your choice. Do one first, dragging and dropping it to the new folder just for practice. Then try using the ctrl key (you must hold it down each time you select a new picture, or just keep holding it down) Select several at random, and drag them to the new folder. All of the selected items will transfer. If you want all of the pictures, go up to the 'edit' menu, click on 'select images' and choose 'select all' Then drag and drop, and they will ALL go where you put them.

I know of Select all! So if I do that I just need to drag and drop only one image to chosen folder and the rest will follow as long as I'm holding down the ctrl key ? Is that right? If so sounds simple enough!

Well at least you have no yellow thingys. Just for fun you can try
the same procedure by using evu and clicking on your folder that
contains some pictures without the camera. Select a bunch of them
using the procedure outlined and simply put them in another place
of your choice. Do one first, dragging and dropping it to the new
folder just for practice. Then try using the ctrl key (you must
hold it down each time you select a new picture, or just keep
holding it down) Select several at random, and drag them to the
new folder. All of the selected items will transfer. If you want
all of the pictures, go up to the 'edit' menu, click on 'select
images' and choose 'select all' Then drag and drop, and they will
ALL go where you put them>

I know of Select all! So if I do that I just need to drag and drop
only one image to chosen folder and the rest will follow as long as
I'm holding down the ctrl key ? Is that right? If so sounds simple
enough!

When you are in EVU or DPP, click on a picture you want. Hold down
the control key (Ctrl) and click on all the rest of the ones you
want. Then drag the whole mess to the folder you wish to place
them in. I believe this is what the prior post is referring to.
There are other ways to select, but this is probably the best to
selectively choose the ones to place in your folder. I still do
not understand why your card reader will not function properly. I
know you are using windows xp. Do you have any of the service
packs installed (sp1 or sp2). Also, can you click on control
panel, open up the 'system' icon, select the 'hardware' tab, select
'device manager' and tell me if you have anything with a yellow
thingy in front of it (now there is a descriptive word). I don't
have any so I don't remember if it looks like a question mark or
possibly an exclamation mark. Let me know what you find.

I have no new images so far today, but when I do I will try your advice on uploading more than one pic.

thanks again chet, regards Katy

If you use select all you don't use the ctrl key. The ctrl key allows you to select only the images of your choice, for example image 1,2,4,5,6,19 etc. There may be images on your camera that you don't want to waste the time of downloading to your folder. After the images you want are transferred you can format the card in your camera. This is really very fast, quite possibly as fast as your card reader was, and you don't have to remove the card. When you click on your first image, it will highlight. Then hold the ctrl key and click on only the ones you want. They will also highlight. Now you simply point your mouse at one of the pictures and drag it where you want it. All of the selected one will go with it. If you click on a picture and fail to drag it, it will nullify the whole procedure and you will be back to square one with only one picture highlighted. Try it with a folder with picture in it. Drop them on your desktop. They will stay in the folder as well, and you will have copies on your desktop that you can later drop in the trash.

Your results are fine.

A true hot pixel would show up at any (e.g., 1/100 sec) shutter speed.

The numbers below are just noise effects, which are a function of focal plane thermal noise and so on.

Your results are similar to my own and no reason to consider returning the camera.

Phil

I did the Starzan Dead/Hot pixel test for my new Canon EOS 20D with
18-55 lens cap on in a dark room. Noise Reduction = Off, Mode = M,
Set to MF. No Dead Pixels (using default setting of 250). I have
hot pixels (using setting of 40).

Here is the Hot Pixel list:

Shutter/hot pixels

ISO 100:
1/100 0
1/50 0
1 0
2 0
4 0
8 1
15 2
30 4

ISO 200:
1/100 0
1/50 0
1 0
2 0
4 1

It is as easy as you suggested!! Took 12 pics of birds and squirrels in the garden, connected camera to XP, selected all, then dragged and dropped one image and all the twelve were transferred, BRILLIANT!! Just as quick as the Card Reader. I always FORMAT anyway.

Love you Guys,
Katy

Brian, I responded to your earlier post on this subject.

I too have a new 20D & my first outing with it was at night taking moon & star shots. I was dissappointed to find a bright red dot center frame with others smaller ones elsewhere on the frame but not so objectionable.

I went onto DPReview to research hot pixels & that is weher I read your post amongst others.

I ran the Starzen test on some black frames on my camera.

I decided just to try at 100 ISO & 1600 ISO with test shots at 1/10th, 1, 5, 10 & 30 secs with NR off & to run with threshold at 20,40 & 60.

I decided these settings based upon other users figures with Starzen that I found on DPReview......figures on their own are meaningless - I needed a base to compare my camera against.

I found other users quoting the following with threshold at 60:

iso 1 sec 5 sec 10 sec 30 sec
100 0 0 0 0
100 0 0 na 1
100 0 6 11 27 (mine!)
1600 0 3 1 2
1600 1 3 na 41
1600 22 44 51 113 (mine!)

Same again but at threshold 40:-

iso 1 sec 5 sec 10 sec 30 sec
100 0 0 0 0
100 0 0 na 2
100 1 11 20 31 (mine!)
1600 0 7 2 7
1600 1 5 na 61
1600 38 54 70 229 (mine!)

.......& you really don't want to see my results at threshold 20! (743 at 1600 & 30 secs!!!)

I also decided to test my camera at 1/10th & 1600 - a reasonable low light handheld setting with a wide angle lens I felt, rather than an 'excessive' long exposure on tripod at hi iso which I will not reguarly do.

At 1/10th sec & 1600 iso i got the following:

60 threshold 6
40 threshold 10
20 threshold 32

Comparing my results to the others i felt I had a relatively 'bad' camera which justified a visit back to the shop. What really clinched it for me was that I had a cluster of up to 9 pixels (ajoining) which lit up bright red center frame. I know better than to expect a 'perfect' sensor - but I felt mine was on the wrong side of acceptable - Yes, I know I can touch up in photoshop or use NR or dark frame subtraction - but I would prefer to start with a better base before employing such methods.

I used "alt PrtSc" keys to screen dump from Starzen into an Excel (could have used Word or writepad etc) sheet the results from Starzen along with the DPReview texts that I compared to & printed this info off (along with dark frame pics on disc) & took them into the shop today - I calmly & politly explained my position & enquired if they could do a camera exchange. The shop in question was really good & although they did not have any 20D's left in stock they have promised to get a couple in in the next day or two & will allow me to perform the same test on them before deciding which to keep. The shop in question was Jessops in the UK (Hedge End nr Southampton), this is my first significant purchase from them & they have so far been excellent regarding customer service.

I hope this helps you to decide your position Brian - I noticed the hot pixels on shots which first alerted me to investigate further, rather than testing for the sake of testing & then being dis-satisfied.

Thanks everyone.

And Thanks PC Wheeler. I decided to keep it for now and see if I have problems in real life shooting when I have time. I bought the 4 year plan at Best Buy so if there is a problem, it will be fixed. Of course if it is within 90 days of purchase, I can still get Canon Irvine to fix any problems without incurring any labor fees.
