the second way


I take a photo with bigger view than I want , thin I crop ( 100% ) to have the view I want (500x375 pixels )


as you see in the photo down ( the green Square is to show you where I am gonna crop 100% after taking the photo .

so which way is right is right to have a good sharping photo ?



by the way I found the photos in the internet

fill the frame with the clock and get you exposure correct - both shots are underexposed above. Then just resize the image in PS or other editing program

Not sure without trying it myself. I would think that photographing the clock closer then resizing down would be best. The focal length you use could also play a part in sharpness. I'm assuming that the f:stop would remain the same either way. It's also possible that using your two approaches you might not see much difference at all since you're not planning to make the final pix very large.

+1 for this method.

Also, the images above are not equal in ISO or SS. If you really want to compare, have everything equal then check it.

The first way.

Gee, with digital it costs nothing to conduct a simple 'try it both ways and decide which is best'.

It's a funny looking clock, but it's all I have handy:

294483

I cropped the lower picture to 600 X 600 pixels, then cropped the upper one square and resized it to 600 X 600.

294484

No sharpening was applied to these pictures.

The fine print, blown up to 200%:

294485

A bit of sharpening makes the difference more obvious:

294490

So we can see it's best to crop as closely as we can in the camera rather than crop a large image in post processing.

Over-thinking it much?

At 500 pixels wide it probably doesn't matter at all since even if you crop you are reducing the resolution by 75% in each direction.

You also want to factor in a good familiarity with your lens' "sweet spot". Many "affordable" lenses get soft at the extreme zoom ranges. For example, some hypothetical 70-200mm lens may be less sharp at 200mm than at 100-150. If you're using some "L" glass than just ignore this rant. ;)
