is this right or wrong?? :shrug:

I am slightly confused and seam to be going in circles.

I am dyslexic so that dose not help. some times I do need thigs spelt out for me.. :cuckoo::cuckoo:

sorry and thank you
 
You can just goto Image and click on resize canvas, put in whatever dimesions you want. This will change the size of the image that would be saved but without downscaling the original image. Then you can just drag the image around to the part that you want, only what you can see will be saved not the whole image.

Output file has smaller resolution but the image used in it has not been downsized at all so would be a 100% crop.

I believe that is correct, someone please correct me if i am wrong.
 
What you are doing will give you a 100% crop, but is there any particular reason why you want a 100% crop that exactly fits your monitor?
 
No I just guess that what you had to do use the settings that your monitor was set to

I have got that wrong then

So what can you have them set to

Thanks Jamie
 
In CS5 (I expect elements is the same) go to the 'Zoom' tool, select 'Actual pixels' then select an area (rectangular Marque tool) and under the 'edit' tab select copy.

Select NEW from the 'file' tab, it will display the size of your selected area I usually change it to 1024 x 768 or 800 x 600 then rename and press ok

When NEW area has opened under 'edit' tab press paste, job done.
 
hmmm.... stil :thinking: over this

why is a 100% crop different to just cropping a shot?

is it because it's not reducing the amount of pixels in the crop????????

<I know, dumb question, please bear with me>

I keep seeing folk ask is it a 100% crop... and think, how is that different to a crop :help:

Lets say you start with a picture 3000 x 2000 pixels from the camera. You decide to crop it to 1500 x 1000 pixels. That is a crop. You then upload it to somewhere like facebook or a web gallery that has a max of 750 pixels on the longest side. When you upload, it will resample your 1500 x 1000 image to 750 x 500. You are now looking at a smaller number of pixels than your original crop (of 1500 x 1000) so you are seeing 1 pixel for every 4 that was in the original crop - the software has thrown away 75% of the information in your original crop. 1 pixel on screen is representing 4 out of the camera (2 across and 2 down).

When you're trying to judge things like lens sharpness, you need to see the data as it has come off the sensor (or as close to it as you can get). Let's take the example above. You've linked to the picture at 750 x 500 and questioned whether it is sharp. Someone has come back and said it looks OK, but they need to see a 100% crop to really make a judgement.

What you then need to do is go back to the original 1500 x 1000 image and crop out an area of detail that is 750 x 500 pixels. When you then upload that to your fave image hosting site, the software doesn't change any of the pixel dimensions and just uploads the file direct. Now when you link to the picture, you are seeing it without any software throwing away pixels - you are seeing it on the screen - one pixel on the screen represents 1 pixel out of the camera. You're seeing it at 100% (1:1) hence 100% crop. In reality "100% crop" is shorthand for "an uploaded picture that gives me 1 pixel on screen for 1 pixel from the camera". If you have web hosting that doesn't limit pixel dimensions (e.g. Flikr Pro), 100% crop could just be the original image itself.
