ICloud email size of photo?

Question

Using Mail online when attaching a photo there does not seem to be a way of choosing the size
small, medium, large etc
Is that right?

Answer 1

No most jpeg file you save will be much  smaller then 10MBytes.  The exception would be if you stitch a lot of images together and create giant giga Pixel images. Your image is only 10Mega Pixel.   Using a high quality jpeg setting like 10 will produce a file size well under 10Meda Bytes. Jpeg uses data compression.  Look at my files I shoot with a Cannon 1d mark 4, Its a 16Mega Pixel camera. I shoot RAW and my RAW file sizes are in a range of 30MB down to 18MB cannon uses a loss less compression in its RAW files. When I process these raw files in Photoshop the PSD files I save range from 500Mega Bytes to 30 Meg bytes in Size.  PSD files are Layered files Jpeg does nor support layers so If I open one of me 300 Meg Byte PSD file the Image is still a 16 Megs Pixel image. When I save a Jpeg image from the document Photoshop is editing from my 300 Meg Byte PSD File at quality 10. The largest Jpeg file I see for not stitched images are smaller the 7Mega Bytes.  When you save Jpeg images they should all be smaller then 10Mega Bytes unless you interpolate you images why up in Pixel size.   I have had an image printed on canvas for me.  The Canvas size was something like 6' by 8'.  When image are printed that large they do not need to be printed at a 300doi resolution.  I interpolated my image up in size to print at 100DPI  6x12x100=7200 Pixels by 8x12x12=9600 that made the image pixel size 7200x9600=69,120,000pixels. Near 70Mega Pixel. I just open a new document that size rendered clouds sharpened and save a jpeg image quality 10 is save at 7.5MB in size.
