Heading back to Minnesota and Iowa next month to visit family so I asked for a "micro" camera for Father's Day. This Canon is smaller than a pack of Marlboro box and boasts 7.1 megapixels and a 3x optical zoom.

It's taken some great family snapshots, so thought I would try a few wrist shots Saturday of my Alpha. Here are two "keepers."

Hi Tom,

that's a great little camera as "carry everywhere" - and a great macro capability too. Actually I considered that ELPH (called "IXUS" here) when I bought my new toy.

Looking at your wristshots your cam appears to be superb regarding "image noise" (sheer envy here...!). Though I prefer mine due to it's wideangle capability, I have to admit the noise generated by my cam's sensor is much more apparent than that of your's (envy again!). Congratulations on a great cam!hand6.gif

And wristshots done with it:

Nice Lumix. I don't see the "noise" though. I'm anxious to try out the Canon with my light box, maybe later this week.

Here's a shot of my youngest, Alex, that I took right out of the box with the Canon. Went to his Little League team post-season swim party.

Great pics! hand6.gif

I plan to replace this Sony 3.3 mp camera I have had for 4 to 5 years this Fall.

Plan to go for something 7x mp or better. Maybe another Sony but not sure. Allot of great cameras out there now. ;)

Hi Tom,

First, I am spoiled, because I mainly shoot with my DSLR and there is no noise problem.

And trying to explain sensor noise ain't easy. Your pictures nearly show no noise, while mine show quite a lot.

All pocket digicams do have a noise problem, some more, some less - it's caused by the tiny sensors used in these cameras. Your ELPH with 7.1 MP and roughly the same sensor size as my LUMIX with 10 MP must have a superior noise performance. Just because the single pixels on your sensor are larger, and not as much signal amplification is required.

The effect of sensor noise is about same as the "grain" we had on film.

2 crops from my wristshot above in 100% size (as from the cam) will do the explanation of "noise":

1. with noise, see the grainy appearance in the unsharp areas, so the noise performance of my LUMIX ain't particular great.

2. same shot without noise (removed with Paint Shop Pro X):

Though the advertising campaigns of the camera industry do suggest the opposite, in fact more megapixels do not automatically give better images. Too much other factors are incolved.

P.S.
And as we are just showing off our small ones, here's my son, greeting all of you while riding a peacock:

(And yes, this shot was denoised before posting)

That is one cute guy there, Markus! You must be very proud of him.

Thanks for the lesson in noise and sensors - - I'm a "beginning intermediate" in digi-cams, if that. I also use PSP X. A couple questions:

Where do you filter out the "noise" as you did?
How do you compress image file sizes in PSP without significantly degrading the image quality?

Thanks in advance. BTW, I'm about to try a few pics outdoors of my Seagull!

Hi Tom,

Thanks - he is cute!

1. Noise removal in PSP:

I use the "Digital Camera Noise Removal..." dialog, can be found in the "Adjust" menu:

When changing the settings (higher number = stronger effect) you get a preview in the right of the two small windows. You can change the area of preview by just grabbing the contents of the right window with the mouse and pushing them.

2. JPG settings in PSP:

Use the "Save as..." dialog from the "File" menu. In this dialog you can change the general JPG options by clicking on the "Options" button, the following dialog will appear:

After setting your options and clicking OK, you have adjusted and saved your general JPG options. These will be used every time you save just using the "Save" icon (Small disk symbol). Note that I generally use the lowest compression (value = 1), because every saving of a JPG file with compression will degrade image quality.

In the above dialog box is another button named "Run Optimizer". This can be used to temporarily change the JPG settings for the current saving process, a preview of the loss of image quality is provided. Here again the preview area can be selected by grabbing and pushing the right image:

I nearly always use the "Quality" tab, rarely the "Download Times". The "Use Wizard" button is useless (for me), tried it once, found it unsatisfactory.

I rarely use a compression value higher than 35.

Leave the "Save Exif data" checked if you want to preserve the additional information your camera stores inside the image file (Exif data contains: Date taken, Camera settings, Camera make and model and much more - a huge amount of useful data). Uncheck this option if you save for web posting and do not want others to know what camera you have used. I save my files always with Exif data, also for web posting, because my DSLR allows me to store a copyright remark inside the Exif data.

Cheers, hope this was helpful,

Markus

Markus...you da MAN! I'll try out your suggestions.

In the meantime, I went outside and took a few shots of my Seagull with the new Canon, plus a few inside. Here are four that came out best.

Photography is for sure not even close to a strong point for me. But gave it a go outside. :D

Tom,

I'm trying to decide between the Canon SD1000 and the Casio EX1050. Are you using one of the programmed settings on your Canon to take those shots?
