Dude... I never write comments on youtube. But you earned that. You are so astonishingly great at explaining technical backgrounds in an easy, understandable and yet precise way. Very well researched and simply great tought. Your channel is so underrated and not even close to the appreciation you deserve. You should have 2.800.000 followers, not only 28.000...
THANK YOU for your work and efforts!
Wow! Thank you, Andy! That's probably the best feedback I ever got 🤗! VERY much appreciated. Best wishes to what I think is our neighbour in the east (considering the name 😉).
@@wolfamri neighbour in the west, actually, I'm from Switzerland. 😄
Have a nice day.
Geeez. How could I get that wrong. of course I meant Switzerland! 🤦♂️🤦♂️🤦♂️
I am also similar to you Andy, and this videos are extremely helpful to find clarity in all the photographic world's complexity!
Thank you so much, Frank. Really appreciated feedback 🙏🙏
After experimenting 100 hours with soap bubbles I still discover totally new colours and shapes in your video, I need to get back to that topic:D
😂 I have to agree. It’s addictive. I’ll make a soap bubble video and will link to your videos for the tech specs. Can’t beat the soap bubble king 😂
It’s always fun to finally learn what a number means! Now on to figure out the details behind GN and Watt Hours! Awesome video, thank you!!!
Thank you, Jason. 😂 yes, that’s on my list 🙌
Huge thanks! Practicing a lot sometimes makes theory fade away... Your videos help recover what was learnt and bring everything in order again 🙂👍 Can't even imagine how valuable they are to the novices (which we all once were)! 😎🤘
Thanks again, Paul! Great to get this kind of feedback!!! Спасибо! 😉
YES. A Soap bubble vid would be great.
Thanks, William! 🙏🙏
Brilliant!! Thank you for making complicated terms easy to understand!
Thank you Yanni 🤗🤗
Very nice and easy to understand video is such a complicated term. Thank you and yes a soap bubble tutorial would be highly appreciated 🙏
Thanks, Vinayak 🙏🙏
Awesome video!!! Very well explained. Yes to the soap tutorial!
🤗🤗😘
Great base (core technology), the foundation is required before you can build anything! KEEP UP THE FIGHT!
A great CRI with diffused 5,000 Kelvin lighting, heavy drapes on the windows, a neutral gray work environment, a color calibrated work flow, makes editing easier, faster and more profitable! Emphasis on quality and profit! Yes I have one ugly room in my house which is my editing studio, however it pays for everything else!
What amazes me is that 25 years ago the print industry paid 1.6 million dollars studying this and developing standards that nearly everyone ignores. This process is best thought of like a mosaic, the more pieces you adhere to the easier the repeatable quality.
Thanks for the video.
Thanks, David. I guess I have to make a video about color calibration and consistency once. But to be very honest with you, I am a bit sloppy in this regard. I don't do much for print and when targeting peoples monitors, you are on lost playgrounds. Every display is so different, that it might be better to adjust colors for an iPhone rather than make a correct calibration. Not even talking about different browsers on the same computer showing the very same youtube video differently.
@@wolfamri Color calibration is easy. Having the dedication to serve the client is something else. I calibrate my display and control my editing environment. You end up with a file for print correction, I then create a web image and post it to hidden web siite to view on different devices. As 2 base core web destinations I find that images on touch screens and non touch screens look different. However most clients pick the image for touch screens today.
What this has evolved into is that purchasing images on the web for projects has become problematic. I regularly get projects where I bill more to correct poor web purchwsed images then what they paid for the images in the first place.
In general the ability to view images through browsers is awful. An issue that has no resolution that protects the rights of the image owner.
The worst stuff I've seen is making camera profiles.
Great to have such an expert on board. Do you know, is there a way people could calibrate their smartphones and tablets without using a dedicated device? I have two ipad minis and one 10". They all have different colors and brightness levels. I don't care much, but I wonder what would be the best approach in regard to monitor calibration to overcome this issue with e.g. clients.
@@wolfamri There's the answer that works and then there's marketing.
The real answer, No!
Marketing will say anything to milk your money.
Because of the multitude of displays and software the very best you can do is to work with a calibrated system in a controlled environment to create your web or GDI output file as an sRGB file.
Place the files on line and view on different platforms, adjusting for destination.
Pro image editors are color managed, browsers say they are but regularly fail. For forums, blogs Facebook and others they are significantly unreliable.
The one core issue is that any display is only calibrated for 1 very specific lighting conditions. I know that there are devices that monitor those changing conditions but if you watch them work you may be disappointed.
From a color grading or correcting perspective color is about what you like. Color management is about getting repeatable results that you like.
I work as 16 bit Prophoto RGB for a multitude of reasons. I then save as required.
@@wolfamri Color management is not that complicated and is just as important for web as it is print.
Calibrate your workstations, edit for your destination. My friend decided all his web mages will be done for cell phones. Assuming you have quality display systems. Once your systems are calibrated you can run the same presets on all machines and get good results.
We urgently need a bubble video!!!
If need be, I'll make it for you only, dad 🤣
Always easy to understand 😊
Thank you, Martin 🙏🤗🙏
Awesome and easy to understand
Thank you 🙏🙏🙏
Nice and well-explained video! Could you please also make a video about camera filters, including types of camera filters and how to choose good quality filters. Thank you in advance!
Thank you 🙏🙏. That is on my list. In fact I already filmed a part in summer 😉
@@wolfamri Perfect! Thanks for the update!
Thank you, & it's a yes please from me for the soap bubble
Thank you, Tony 🙏
Nice name. Better than before
Thank you! People started recommending the channel by my name, and nobody found it. Then I decided it was the right time to even shorten my real name and make it easier for native English people 🤣.
@@wolfamri good for you brother. i feel you wish our effort will payed off soon with youtube algorithm.
Thanks so much!!!!!
Thank YOU, Angelo 🙏🙏
Sir, I am really interested in landscape photography. A movie explaining the crucial aspects of landscape photography like composition, lenses etc will be highly appreciated including editing tricks...
Thanks for your idea, Pranjall. I have planned a video about composition, but it is a good idea to make a complete video about landscape photography.
@@wolfamri sir I have also left my first decent landscape image for you to critique, on your instagram. Please find some time and help me improve my images by critiquing my photo. I will be going to the same location again soon so please tell me how I can improve my shot. Your advice will be crucial as I have learned all my photography from your course only. Thank you.
Hey can u please make a video on how and on which website we should publish our photographs.
Thank you for your great help via youtube videos
Thanks, Siksha. I’ll consider that, but I’ll have a long list of videos to do 😬😂
@@wolfamri Thanks for the quick reply.Thank u verrrrrrryyyyyyyyy much.
But u will make video on what i have reuested n?????
What's your take on Fuji X-T200? Is it a better option over Nikon d3500/d5600?
I can’t tell about the x-t200, but the 100 in my test (have you seen that?), was rather disappointing.
And yes I want a soap bubble tutorial
Noted 😉. 2000 more and I’ll do it 😂😂😂j/k
@@wolfamri 😂
@@wolfamri Here's one more on the soap bubble video. So Yanni now we only need 1999. How is it I never saw this video until now? Did you hide it?
Hahaha love it
Thanks, Cody 🙏🤗
GOOD MORNING,GOOD AFTERNOON,GOOD EVENING,GOOD NIGHT SIR,whenever u r reading my this comment.
Sir i have a small request to u.
Sir i have shot some images with my camera.
Sir can u please have a look at it and please give review on that images.
Also notify me about the corrections that i should make in my shooting for better images and editing.
Sir please have a look at my images.
THANK U SIR.
Good morning. Let me recommend posting it in my facebook group and tagging me. But please don’t forget to read the rules first 😉
@@wolfamri Sir i dont have a facebook account.
Sir can i send on your gmail account personally.
Sir please
Siksha, I‘m afraid I don’t want to publicly show ky email because I would get flooded. Beside that I like to do it on public places. First because photography is subjective and getting diverse feedback is better than one guy. Second: because then always multiple people can learn from one person asking. We can only be strong together 😉.
@@wolfamri okkk
@@wolfamri sir i will not misuse ur gmail
Only i will send the images
And u review on it
Sir pleaseeeeeeee
