ISO settings

[Kelly Grannell]

I didn't take this picture, but WOW! ISO 12,800 using Canon 5D with NO noise reduction.

Holy good god...

That's HIGHLY impressive.

I still love my Nikon though. I have to post process with NeatImage on some shots, but it's not bad.

 

[Kelly Grannell]

yeah, according to the photographer, he hardly can see the object because the lighting condition was virtually nonexistent.

After reading the post from Fred Miranda about a guy pushing his 5D to ISO 12,800, I'm applying his method to my oldest dSLR, the 300D / dRebel.

out of camera, as is:

after noise reduction:

Looks good.

How is this accomplished other than underexposing if you've set your camera for the highest ISO is has?

The 5D only goes to ISO 3200, where are you getting 12,800 from?

 

[calvinjtodd]

I just looked this camera on the canon web site, it has a 12.8 MP sensor, maybe this is the answer to the possible confusion as it does quote a high of 3200 ISO.

 

[Kelly Grannell]

This was done using Wasia hack to get ISO3200 plus 1 stop underexpose.

 

[Kelly Grannell]

nope, he set the exposure to -2 (2 stops under expose) then boost the level back up.

The camera itself can do ISO6400 under "boost mode".

Kelly I think your wrong on this, the camera cabn only go to 3200ASA. I'll going to look into this though.

 

[Kelly Grannell]

My apology, 3200 under boost mode. The rest of the info is correct, he boosted the ISO by underexposing the shot by 2 stops and re-boosting the EV by playing with the level.

What is Wasia Hack?

What is Wasia Hack?

The original Digital Rebel or 300D as it is know outside of the US was an identical camera hardware wise as the Canon 10D but many of the features were disabled by the firmware that ran the camera. The Wasia hack was new firmware developed to allow the all the hidden features of the Rebel to be used by the owner. This was done by a Russian without Canon's consent so it is known as a "hack" of the original firmaware. Any changing of the firmware also voided the Canon warranty but many have said on other boards that Canon repaired their Rebels even after the hack was installed.

Here are the changes to the camera after installing the hack:

Enter Flash Exposure Compensation using SET button

SET button function when shooting

Shutter release w/o CF card

Flash sync speed in Av mode

RAW+JPEG rec. Sets the quality of embedded JPEG

Mirror Lock up

Selects the autofocus mode: AIfocusAF, ONEShot

ISO 3200

Great examples Kelly (though the subject is questionable )

This is one of the thing I want to do with the upcoming full moon. I originally had my ISO at 1600 because I didn't use the tripod at first and wanted to try and cut down on the hand shaking. Then I got the tripod and forgot to change the ISO. I'm still hoping the snow storm will be gone by Sunday night. I'll try ISO's of 200, 400 & 800 to go with my 1600.

I can assume same f/stop. Funny, the higher the ISO setting, the more the floor or counter or whatever that stuff is sitting on loses it's texture. Also, I cannot see any more graininess in the higher ISO setting. Interesting...

Any chance of getting them all the same size?

 

[Kelly Grannell]

I'll try to do that tomorrow but currently I'm using a PC with no resizing software. The images were uploaded directly from my CF card.

The carpet is losing its texture basically because the carpet it somewhat sparkly, the higher the ISO, the less sparkly-vs-non-sparkly ratio which causes the effect of lesser texture.

The graininess is virtually undetectable because of two things: 1. It's a Canon dSLR, they are famous for lower than average digital noise (dSLR themsleves tend to have lower noise to begin with thanks to their larger sensors. 2. It's smaller in size. You WILL see the noise when you print around 8"x12" at ISO800 or higher. You WILL see digital noise even at ISO400 when you're using a point and shoot camera, or in many cases, even at ISO100 when you're using Kodak point and shoot (I've never seen grossly perceivable digital noise at ISO100 with any other camera than Kodak).

Important note: not all pictures will show digital noise. Pictures with more saturated colours or pictures with more black/dark colours will show digital noise using the same ISO as pictures with lighter colours.

 

[Kelly Grannell]

oh, and to asnwer the other question, yes the aperture are identical too.

 

[Muushka]

Very interesting..... thanks
