Colours - is it just me?

[KateW]

I've noticed that when I click on a posted image to view it large, the colours look very different. In the case of Fuji's gerberas, the original looks almost red, but the enlarged version looks quite yellowish orange. Is it just me, or do other members find this? My monitor is calibrated with Huey, but that shouldn't make a difference.

Not sure about colour change Kate but the images look much brighter to me In Fuji's Gerberas

.... the colours look very different

And when were you last at the opticians?

Seriously though, my monitor isn't calibrated and I can't say I can see a difference in colours.

It's my ......Magic Processing.......done through my brand new supersharp eyes Kate ;-)

Ah, that must be it, Fuji!

I can't say I've noticed any difference, I don't have a calibrated monitor though.

we had a calibrated monitor at school, poor lad had rickets

Checked on the iPad and the colours are identical - ill have a gander later on the Mac to double check.

ive noticed that images look brighter and more colourful on some and not on others not sure why

I guess the old " Calibrated Monitor " issue may hit here again, but also when you starve an image in compression, then the enlarged version will be over starved, so colour detail may suffer...

[Heather]

i actually find the colour and details are better when you look at the larger picture

[KateW]

Steve, you may have a point there. I never thought of compression being the reason.

[stevedevil]

I could bore you all in " Compression " but it will alter the colour in a Jpeg, and then once enlarged the results do suffer..

Whether your monitor is calibrated or not may make a difference to the colour and detail you see compared to the colour and detail revealed on another persons monitor, but it will not make a difference to the colours from the small to enlarged version on the same monitor I do not think, that must be down to some other factor. I too do not see any significant colour difference between the small image and the enlarged one.

That's what I was thinking, Dave. I can only think that, as Steve says, it's to do with the compression.

Hi Kate,

The more you compress the image, the software in the compression looks at each pixel, and say you have 10 near black pixels in a row, then the data is stored as black x 10, so imagine the whole image having these rules set, the more you compress, or starve the image of bytes, the more the colours are blended into the next pixel..

All Jpeg images are stored this way, so when you open a jpeg and re=save it the image loses data, so there is a loss somwhere, maybe not to our eyes as there are millions on pixels now on newer camera's, but I always save in TIFF as this has no compression on pixel data.

Hope this helps

I only use JPEGS for posting to Forums or emails.

Otherwise I work on TIFFS OR PSDs........my CS3 doesn't take SONY RAWS straight from camera, so I have to use Photoshop DNG Converter and use DNGs fir processing then they are saved as PSDs......if that makes sense?

Thanks Steve.
