So my question is are u saying that that film which u gave a link is as good as Apple stock antiglare screen?
Thank u
My background: I'm a pro photographer with over thirty years experience. I wear glasses that have been fine-tuned for computer use; otherwise I don't need reading glasses. I am very particular about the quality of my displays. My images are published in a wide variety of formats, some of which are quite demanding when it comes to image quality. I'm not just posting images online or making 4x6 prints.
All I am saying is that when I compared the displays I could not see a marked difference in how images were rendered on the them.
I have also read myriad anti-glare film reviews and user reports. Some films have relatively poor reputations; they also tend to be the less expensive options, natch. I went with a relatively expensive film that had some very good reviews. I have used it on both my iPad and MBP and I am quite satisfied with the quality.
Having said that, none of the portable Mac displays are great for color-critical work. There are inherent limitations in the type of LCD panels Apple uses and that includes the high-res anti-glare panels. But after calibrating and some experience using a portable display it is reasonably easy to obtain very good results. But for really critical work I use a high-end NEC display. Doing a lot of image editing on even a 15" is not much fun... I've never considered a 17" because of its size, cost and the quality of its display. For the same money you can get a 15" MBP and a very nice LCD display that will beat the pants off the 17" screen.
Like someone mentioned display preferences and what is "good enough" is very subjective. The only way that you will know for sure if a particular film will work for you is to buy it and try it.
In my case I wanted a more portable MBP with an anti-glare display and I wanted to try a less expensive option before I sent the MBP to Tech Restore for a matte display replacement, which costs around $200 for a 13" MBP. Spending $35 was a small amount of money to see if the Power Support film would meet my needs. It has and I saved some money.
