I don't claim to be the source of ALL the $60 billion Apple have in the bank but I have made a good contribution!!! :lol:

Hi Rich-

I haven't seen one yet...and won't be looking for as long as I can wait :-)

I bought a new iMac when they had the last upgrade about 6 months ago - I just lusted for the fusion drive, lightening cable, faster wifi and bit the bullet a touch too soon (:

I've been updating Macs at intervals more than twice as long as I used to do with PCs (making them actually cost a lot less :-)

but I will have a short cycle with my present one once I see the retinal screen, I'm afraid.

I've also come to the conclusion that mac pro is not for me. I thought it would be and then they took so long to update it that I've gotten pretty (no, VERY) happy with iMacs. And they are still so much less expensive that they are real value and you can upgrade them as need be.

Waiting to hear how long you go until you are back gushing about the retina screen :-)

!!!

Tom

Hi Rich, I think there are arguments for and against ultra high definition screens.

The usual viewing distance from a screen tends to be around 600 to 700mm. At that distance I can't 'see' the detail that the extra definition provides, except the image looks crisper. I did take a look at these in the Apple store recently. My retina iPad which is viewed from much closer, say around 400mm seems pretty crisp.

What I am asking myself is when do I NEED to see that detail during processing?

The only time I really need to get down to pixel level editing is when I am cutting through layers to reveal other layers beneath, for example with the 'Oakdale' IR image which has about six layers. When I erased the top layer to reveal underlying layers around the rigging of the boat I did have to zoom in close, right down to maybe 400% or closer to keep the edit clean, other than that I don't think ultra high definition helps but even then I would have to blow it up even more just to see the image pixels.

Other than that I like to see the entire image at a reasonable size and assess the effect of any adjustments I am making across the entire image. Whether seeing the individual pixels at 1:1 helps that I don't know, I guess it can't do any harm, it's probably good when sharpening. I tend to sit right back when making adjustments so I see the entire image rather than focusing on the detail.

The ultra high def certainly produces a crisper image but for close in pixel level editing I don't see it as a solution, I would still need to zoom in to very high levels of magnification.

Other than that the iMac is a very capable machine for image editing, especially with a decent amount of RAM and a Fusion Drive.

I feel far more important is to have a second (cheap, smaller and low res) monitor for the tool pallets and other 'clutter' which otherwise obscures the image, no matter how large the main screen may be. This is a breeze with an iMac, a £25 adaptor and an old PC monitor does the job perfectly. Most households have old unwanted 17" screens lying about, they can get a new lease of life and become an inseparable companion for the main screen.

I'm thinking of actions like sharpening where you need to view the image at 100% to see the effect, otherwise the internal resizing for the view gets in the way. This would allow you to do that whilst still seeing all the image on screen (at least up to 14MP - a D800 will still be more than 1 screen).

If we had bought Apple shares in the mid 1990"s would have been sunning myself by now even after capital gains.

Yes but back then computers were a stupid geeky device which caused frustration and mayhem wherever they were employed.

Remarkable how the focused developers minds eventually produced a device which has evolved into what we have today. We have a way to go yet, I doubt anybody can foresee where this journey is taking us but I am enjoying the ride! :thumbsup:
