  1. Geological feature ID

    Very useful. I've not been on the BGS site for some time. Will check that out.
  2. Geological feature ID

    If the vertical face is definitely part of the same dyke, then it is just chemical weathering.
  3. Geological feature ID

    Sorry I didn't explain what I meant about the conchoidal fractures very well. I wasn't talking about the linear and sub-linear joints or cracks - these may be cooling joints and the horizontal ones may have formed if overlying rocks were eroded which often results in sub-horizontal joint formation depending on the rock. What I really mean was the appearance of the fresh rock surfaces (pink and yellow) which look extremely smooth and fine-grained (probably originally glassy) and which might fracture conchoidally if hit with a hammer (which might be illegal here). Some of these fresher exposed surfaces look like they have that type of fracture but no I wouldn't use that in the description. It is best to avoid interpretation anyway without detailed study. From experience I would think it is rhyolitic which essentially means a fine-grained or glassy igneous rock with high silica content which could have extruded as a lava flow or lava dome or it could be a high-level intrusive rock which cooled very rapidly. But it could be a weathered basalt as you infer if it is the same dyke as the dyke is so dark that I reckon it must be basaltic or thereabouts. Without seeing it in the field I would hesitate to say anything further about the rocks really but I was thinking that the second picture was of the rock that the dyke intrudes. Without understanding the field relations and detailed study it would be impossible to say which is where the BGS description and the scientific literature come in. However, I would think such pics are unlikely to sell as they are too generic and vague. The dyke is different - that appears to be a good example of a generic basic or mafic dyke. But I think the market for geological images is probably very small. Finally identifying rocks and their relationships is a lot different from identifylng biological identification. If I was studying that I would want to see it under a microscope and get a chemical analysis before I would say anything much about composition
  4. Geological feature ID

    I'm a former professional geologist (not sure if it was me that geogphotos was referring to as there is at least one more who occasionally frequents the forum). I've never been to Skye but it is famous geologically for its igneous rocks. That is definitely a dyke, almost certainly a basaltic dyke. The rock it is intruding looks to be a lot more silicic, possibly (probably) a very fine grained or glassy rhyolite (looking at the second image which I presume is a side view of the same rock). Glassy rocks like rhyolite break with a conchoidal fracture which is what this rock is exhibiting but I am not sure offhand how you would describe the entire surface. Check out the BGS (British Geological Survey) website as they were (and presumably still are) publishing online geological maps so you can check the geology if you know exactly where you were. These rocks are relatively young (around 60 million years or so) for Scotland and have not undergone any deformation such as folding. All the igneous rocks of this age in Scotland and Northern Ireland (Giant's Causeway) are related to the opening (formation) of the North Atlantic Ocean.
  5. We are probably at cross purposes here and probably not going to get anywhere fast in continuing this discussion as we are using different printers and maybe different operating systems - I use an Epson printer with a Mac. I have a Colour Munki Photo which I use to get specific profiles for my workflow and using full color management is my preferred option (nowadays in Lightroom which is better than Photoshop for printing). I am too busy right now to test out any other options so will have to leave it there - each to his own as they say .
  6. I'm sure most of what you said is very good advice but this is definitely not good general advice in 2018 ( nor would it have been any time since Adobe introduced proper colour management back in the late 90s). The printer is just a machine and has no idea what you want it to do. Colour management is all about consistency. The only time I ever turn off colour management when printing is when I occasionally use Epson's black and white printer driver for mono printing but even then I normally use colour management. As for Jill's problem, if all Photoshop settings are the same, I'm guessing that there must be something in the printer driver on the laptop that is changing things for the sublimation paper and ink but I have no idea what.
  7. Adobe PS CC and the alternatives

    No mine is simpler, no subfolders . I just do it by year and country which is not too many as I don't travel that much. The only reason for making folders at all is for ease of back up which I do manually by copying entire folders which could be several hundred GB to extrenal drives. I am a backup luddite - I don't trust backup software. I never shoot JPEGs so want to render the raws as quickly as possible. The article by Victoria Bampton is very interesting I think.
  8. Adobe PS CC and the alternatives

    I have a very simple folder structure. For my landscape and pictorial work, I just go by the country and the year. So everything I have done in England this year goes into an England18 folder. I use the metadata to keep track of the images. The Lightroom databases is lightening fast.
  9. Adobe PS CC and the alternatives

    First of all the speed of generating previews in the Develop module is way faster now than it used to be and for me that is probably the most important thing. I can't remember exactly when this happened but I think it was in LRCC and not in the standalone version. So when you click on an image in the Develop module and check it at 1:1, it generates the preview within a few seconds and also responds very quickly to any subsequent changes (and I'm talking about 36-46MP files). This used to be a very slow process in earlier versions. Secondly, for the purpose of quickly checking and culling a batch of newly imported images, Lightroom 7 introduced the Embedded and Sidecar previews option which is way faster than it used to be. This needs to be checked in the Import dialog before the import. Something I wasn't aware of but read a while back on the Victoria Bampton (Lightroom Queen) website is that generating 1:1 previews does not affect the Develop module. See the following excellent article Lightroom Performance - Debunking Myths
  10. Adobe PS CC and the alternatives

    Yes I understand. I went from Mac to Windows around 1997 or so and then back to Mac early 2009 when Macs went Intel. I installed a full version of Windows XP on a separate partition and used it while I transitioned. The only program I really missed was Access as I had a number of databases but it was too much of a hassle going between the two and I bought Filemaker Pro which was good enough for most of what I needed and very easy to learn. I stopped using Windows completely after a while. PSCC should run a lot faster than an old version of Elements as it is 64bit. Also it can take advantage of your RAM beyond 2GB which can be very significant. I noticed this going from PSCS4 to PSCS5, most especially when creating panoramas in Photoshop because fo the file sizes (I now use Lightroom for pano creation). I would definitely advocate using LRCC as it has had some major advances over the standalone version - speed and numerous features. The standalone version is now significantly inferior in fact and it is unlikely that you would even want to use it anyway once you try out the new one. If you ever did decide to stop the subscription, then you can reinstall the standalone if needs be. Preview building has moved on a long way in recent versions as well so much faster than it used to be. I can't remember at what point this happened anymore but do try it.
  11. Adobe PS CC and the alternatives

    One man's simple is another man's nightmare...Using Windows on a Mac is not simple to my simple mind and the OS file system is very limited in comparison to Lightroom. The Ligthtroom database is extremely good and the whole import process has been speeded up massively. For example, it is important to be able to see if an image is in focus by viewing at 100% and that is way faster than it used to be in the Develop module which is also fully colour managed. Syncing in LR is also way faster than opening images in ACR. In other words. with Lightroom everything is in one place and very neatly laid out. But each to his own I guess.
  12. Adobe PS CC and the alternatives

    Great. Glad you found it useful. I wouldn't use ACR over Lightroom though. Although the results are the same for a raw conversion, I think the Lightroom environment is much easier to work with for so many things than the Adobe alternative which is Bridge/ACR/Photoshop.
  13. Adobe PS CC and the alternatives

    BIG TIP: I've posted this here before and it would seem timely to do so again. There is no need to worry about Adobe default settings as it is very simple to change the default settings for LR and ACR. This is above and beyond any import or development presets and is well worth knowing about. It is surprising in fact how many users, even experienced ones, don't know how to change default settings. In the Develop Module in Lightroom, select an image and then set the defaults you would like to use from now on. For example, select Adobe Standard as your Profile and change the Sharpening to what ever you like (back to the previous setting for example). You might also say want to change the default Noise Reduction. When you have things the way you want them, hold down the alt key and hit the Reset button at the bottom right of the Develop Module. You will be asked if you want to update the default settings to your current settings. Hit that button hard and don't worry. There is also an option to go back to Adobe Default Settings so no harm can possibly ensue. Now even better than that, there is an option to set defaults that are specific to a particular camera (identified by serial number) or to specific ISO settings. To do this, go into LR Preferences, select the Presets tab and you will see these options at the top of the dialog box. There is also an option there to reset all default Develop settings. So no worries, no complaints about what Adobe is doing to its default settings. I'm guessing Adobe is making these changes to make things easier and to appeal to a wider non-professional market as seems to be the case at the moment. But if you are a serious photographer, you should be setting your own default prefs as a matter of course really if you want to control your software rather than have it control you . This tip can be a real time saver. EDIT There is a similar process for ACR defaults but doing this in LR will change the ACR settings as well.
  14. I agree more or less . However, I have to say that there are very few if any upgrades I have made in the last several years that I have not been very happy with and that have not improved or greatly enhanced my workflow and my photography. For example to name a few, the move from USB2 to USB3 represented a massive improvement in backup times and meant buying a new Mac which is still performing very well. The move from 32 to 64 bit was wonderful and totally seamless on the Mac as there were no separate operating systems to worry about or purchase and represented an absolutely massive speed improvement for me, particularly noticeable when processing panoramas which used to take ages at the 2GB of RAM limit. The incremental improvements in Lightroom over the last 4 years have meant massive improvements in functionality and speed. And I won't even begin to talk about why my recent purcahse of the Nikon D850 represents DSLR heaven and well worth the expense for what it can do.
  15. Hi, John from Clare Ireland.

    Hi John, welcome. I love County Clare as well as many other places in the west of Ireland. Make sure you caption and keyword accurately. For example you have misspellt monastery in your keywords. The captions are important so something like Lighthouse is not adequate. The location field is not searchable so it is a good idea to put the location in the caption and in the keywords as well. Your monastery shot could be a seller at some point as there are very few of Scattery Island on Alamy so if somebody searches for it you will not have too much competition. Compare that with Cliffs of Moher for example. You might even make the price of a pint or two eventually. Best of luck.
  16. That has something to do with Adobe licensing, not the LR application itself so I would guess it is nothing to worry about. You can get information about installed apps by going About This Mac, then System Report - dig around in there and you can see what apps or components are 64 bit for one thing..
  17. I disagree. Software needs to be updated to take advantage of developments in hardware and operating systems for performance reasons. In some cases older software may not even work on newer operating systems or new hardware. A really important example here is the advent of 64 bit Photoshop taking advantage of essentially unlimited RAM whereas older versions (pre-CS5 in the case of the Mac and pre-CS6 I think in the case of Windows) could only use a maximum of 2GB. This had/has very significant performance effects. Another would be the use of graphics acceleration in PSCS6 and later and in more recent versions of Lightroom. Again the performance enhancements are very significant. This is particularly noticeable if working on large files. So if software is no longer supported, then it is likely to be effectively the end of the road although it may be a long road until it no longer works or works well enough to be useful. In the case of plugions for Photoshop or Lightroom, then of course it is going to be important to keep up with developments. And none of that even directly considers new cameras and improvements in raw converters. This may not be directly relevant to the Nik collection but will certainly be very important for DxO users if their raw converter software was to be discontinued.
  18. Time is the problem with that for me I'm afraid. I'm too busy to start trying out something new when what I'm using is certainly more than adequate for what I do, moreover testing a set of tools that haven't been updated for some time and may be at the end of the road (perhaps Adobe will buy them). For me the integeration between Lightroom and Photoshop (which I have been using for more than 20 years) trumps just about everything and there is no other single package that has a combined DAM and top quality raw converter as well as a whole lot of other functions (such as Lightroom's print and soft proofing). I'm certainly aware that a lot of photographers swear by the Nik collection so it must be good. The only reason I interjected here was to point out that Lightroom has a lot of new and excellent functionality in the last four years or so that maybe some Nik or DxO users are unaware of. I wasn't offering an opinion on it or a direct comparison with Lightroom.
  19. New Tesco

    Do you mean an unlikely rational debate between the stallholders then as to whose stall was better or a certain gullibility in not regarding the photographer with suspicion? I would not consider either to be specifically Irish qualitites myself.
  20. I have to say I've not used the Nik collection so can't directly compare but there are some very advanced local adjustment tools now in Lightroom. I used to use Photoshop for a lot of my local adjustments but I now do most of my local adjustment work in Lightroom as it means I am working mostly on the raw files with some final stuff in Photoshop if necessary. I must check out the Nik collection at some point but too busy right now (which is good).
  21. New Tesco

    What does very Irish mean?
  22. Lightroom has had all that for years now. The instant CA removal in LR/ACR has been around since 2014 and works very well. There are various auto transform and distortion control options as well.
  23. UPLOAD

    Open a second browser window or use a different browser.
  24. Which Shooting Format

    I know.It's how I have learned almost everything I know about photography. I have made every mistake known to man (and woman). The trick is not to learn from them and not to keep making them I hope you didn't think I was being nasty to the spaceman. I was just teasing him and I have no doubt he can take it. He has actually picked up and used quite a few of the suggestions I've made over the years which is great - it makes it worthwhile passing on my hard-earned knowledge if somebody acts on it and benefits .
  25. As far as I know, the thing with the scratch disk is probably only important if you are working on very big files and Photoshop starts to use the scratch disk which really slows things down. This used to be an issue before PS became 64bit and could only use limited amounts of RAM but if you have plenty of RAM in the first place and are using a modern 64 bit OS then it is probably irrelevant as long as there is room on your main drive if it does need to use the scratch. I am a Mac user so not up to date on Windows though. PS - you didn't really need to reinstall I'm guessing, resetting the prefs should have been sufficient.
