Hi everyone, I'm a hobbyist event photographer. Currently I'm getting professional projects so I'm planning to replace my 2-yr old notebook for a speedier photoshop and lightroom workflow. Currently the specs I'm working with is 1.4 Ghz AMD-E1 32 bit. I don't have problems with Jpeg files. I edit 10-15 images on lightroom (then exporting files to photoshop, if needed) in one sitting and my unit does the job in 30 minutes, although it's really slow. But lately, since I've been getting more and more pro projects, I will have to work on raw files and I want to speed up my post-processing time. I wonder if MacAir 13" 4 gb will suffice. Below will comprise my workflow. 1. import more or less 50 raw files (32mb each) into Lightroom, use global adjustments to each file (or VSCO preset) and, if needed, edit some files in photoshop as an external editor. In photoshop, I use maximum 10 layers (Viveza 2, Topaz Detail 3, Exposure 6 Blur tool, etc..).... and then save it as Tiff for future adjustments. (I have an allowance of 10 hours to finish all of them) 2. I want to learn video editing... I look forward to working on 3-6 minute video 1080p files. I don't want to incorporate intense filters. I may be using basic transitions, add some music, and texts. I prefer a minimalist approach. 3. (This is also important) I work part time for an advertising company, and I use Google services (adwords, drive, docs, calendar, analytics). I usually open 2 browsers with 7 tabs each at the same time. Do you think the Air can handle all these 3 requirements I have with only 4gb ram? I live in the Philippines, so buying a BTO 8gb unit takes a month or two (I called the power mac center here) before I can get it. I cannot wait due to some project deadlines. I'm planning to get one next week if any answer will solve my problem. Note: I really want to own an Air for travel and longevity concern. I see myself doing humanitarian work in the next three years, so weight is also a major factor. I have been using windows laptops for 6 years now and I replace my unit every two years. So changing brands may be cost effective in the run up. If the 4 gb ram can't handle the requirements, I will consider buying another windows' So, your help will really help me.
