Question about DRebel in-camera sharpening

[lmelendez]

Hi there
I was playing last night with my DRebel and I found the setting to change the in-camera sharpening. So, I put the camera in a tripod, put the 50mm lens and took some shoots (using the timer and mirror lock to avoid movement) to see if I could see a difference in the sharpness...

Well, I didn't see any differences...so I have two questions:

1. What's exactly that setting doing? are the pictures really sharper?

2. I read in another post that if you change those settings to the minimum you can store more pictures in your CF card... would you do that?

Thanks for your comments and advice!!!

This setting only applies when shooting Jpeg. Yes, the images will be sharper because the camera sharpens them according to the level of sharpening you want.

I shoot RAW, and prefer to sharpen my images in PhotoShop... sometimes I don;t want sharp images.

Don't do any in-camera sharpening. Your little LCD won't tell you a thing.

Do it in post processing so you can determine your actual (if any) needs.

DSLR cameras are NOT setup to give you that crisp/saturated "snapshot" look anyway. Most of us print larger than 4x6 and the dynamics change quite a bit.

Hi setprime
I was not using the LCD to see the differences... I was uploading the pictures in PS. But you do have a point... if I'm shooting in Raw, then I can decide if I want to work on the picture later...

Thanks!!

I'm not an expert in that matter, but somebody mentioned (and he sounded very authoritative in his knowledge) that canon's in-cam sharpening is a lot better than sharpening in PS (something to do with algorthems..bicubical vs. something else, or something like that).

It's actually the other way around. The in camera processor has alot to do in a little bit of time. Your PC CPU is better suited to do the job and the software available gives you much more contol over what parts of the image and how much gets sharpened. (PS CS/USM, Focal Blade, Nik Sharpener , etc.)

The 2 reasons you would want to use the sharpen settings:

1 - if you only want to download your images and do no editing to them.

2- if you want to print directly from your camera of CF card.

You are only sharpening the image AFTER it is taken and it does nothing to how it captures the image.
