You will find most of the interiors are dark so a wide angle lens with a large aperture and a decent tele-zoom will be all you need. I did the Amsterdam to Budapest tour on Tauck and loved it have fun.
I have it and love it. I have good contrast, sharp images and I take them up to 16x24 with no problem. It is perfect as a carry around lens when you do not want to carry a bag. It is my go to lens when I am traveling and have limited space to swing my bag around to get a different lens. I have a D810 and I calibrated the lens to it and have no complaints.
Just wondering....anybody use the Nikon 85mm f1.8 for indoor basketball on a dx camera?
I have not shot sports since the film age but I covered HS, DI and DII basketball back then and I found my 1.8 85mm an excellent lens for basketball. Since I was able to roam the sidelines and behind the basket with my press pass it gave me everything I needed in the way of reach to get good full frame shots.
From the looks of your info you have something using up a lot of the memory before PhotoShop starts running. 4GB of RAM is the minimum memory that windows 10 likes it is preferable to have 8 to 16 or more. My PC has 24GB of Ram and even I run into problems when I open large files. You best bet is to buy more memory.
Another place to look is to start Task Manager right click on the toolbar and find "Task Manager". Once you get there click on the startup tab and see what processes are running. Usually you can find 2 or 3 processes using up memory and you do not need them running all of the time. Things like "Apple Push", "Java Update Scheduler" and such can be launched manually by you and therefore disable them so they are not running in background constantly.
You have to remember that Windows uses both physical RAM (memory chips)and Virtual RAM (Hard Drive space). You might want to check you physical hard drive space available. Open Windows Explorer and right click on the hard drive in question C:, D: etc. and then click on properties. That will tell you used and available space on that drive. If the drive space is low you can then go to the web page https://support.microsoft.com/en-us/help/4026616/windows-10-disk-cleanup and follow the instructions to clean up the hard drive. You can do this for any physical drive on the PC. The other step would be go to your favorite computer shop and buy additional memory chips to increase the physical memory on the PC. Memory is cheap and usually fixes a myriad of issues in Windows.
The other place to look is in the control panel under the System icon and then then the Advanced tab click on the Settings button and then again on the Advanced Tab. You can adjust the amount of drive space that is assigned to the system by clicking on the Change Button. Most of the time Windows does a good job of assigning the proper amount of virtual memory but if your drive was low on space it sometimes does not adjust back after cleaning up the drive.
As a former photojournalist (1972 to 1982) the best lenses in my bag were 28mm 2.8, 50mm 1.4, 85mm 1.8 and a 80-200 push-pull zoom used on an Photomic F and an ancient non-metered Nikkormat with a potato masher flash. The 2 lenses that rarely left my camera were the 28mm and the 85mm as they gave the views for the subject matter my editors expected, i.e. close-ups with lots of depth of field and lots of detail in the background, and "head-shots" with good modeling. The zoom was used for all of the sports that I covered with and without the flash. I started with small-town newspaper and moved on up to the regional papers but the editors that I worked with considered photographers as a necessary evil and did not want the photos to overshadow the text.
I took a Caravan Tour of Nova Scotia last year. My wife and I had a wonderful time the guide was a local and had great stories to tell and knew the area well. We flew into NS and caught the bus to our hotel the NS Airport has great transportation to anywhere in the city. We then rode on a tour bus and got to meet new people and places everyday for 2 weeks. Great sites, great food good company not much else to ask for.
"Spies in the Sky" by Taylor Downing looks like what you may want. There is also the book "Flight, Camera, Action! the History of U.S. Naval Aviation Photography and Photo-Reconnaissance" by Douglas Campbell tha might help. I remember reading a book on the US reconnaissance operations but I do not remember the title. It was written by a military officer that was deeply involved in AR from WWI until the Vietnam war it was extremely well written and very informative. I will look in my library and when I find the title I will post it. I worked as a photographer for a Photogrammetric company, hanging on in the back end of single and twin engine aircraft taking stereoscopic images for mapping and then developing and printing the images I took. It was a lot of fun.
I am looking for a book with more technical aspects perhaps with examples. To explain dynamic range, histograms, light metering, white balance, exposure compensation. With both examples of how they work and how it affects the photo and or photos being taken. Any suggestions thank you and in advance hogs.
The New Zone System by Minor White may help based on your list of requirements. It was written way before digital photography was available but it still fills the need. The other books are all by Ansel Adams, "The Negative", "The Print" and "The Camera" again way before digital but the principles still matter.
